DJI Agras T100 Tutorial: How to Install the Lift System Dual Battery Version- FAA Part 107, FAA 137

🇺🇸 U.S.A. FIRST — DJI Agras T100 Dual-Battery Lifting-System Conversion, Power Distribution & Motor-Cover Installation

The DJI Agras T100 Lift System Dual Battery Version changes more than the number of batteries carried by the aircraft. The conversion introduces a new front top shell and power-distribution-board fixing bracket, changes how the lifting flight platform connects to the T100 airframe, requires deliberate routing for both dual-battery and single-battery operation, and replaces the upper cover on every motor before the aircraft is returned to service.

The propeller work is especially exacting. Each affected assembly must be removed with a 13 mm wrench, the new motor upper cover must be installed with four M2.5 screws, and the propeller must be rebuilt with the lower spacer protrusion facing upward and the upper spacer protrusion facing downward. DJI’s tutorial then calls for blue adhesive on the motor shaft and a recommended tightening torque of 150 kgf·cm, approximately 14.7 N·m, before the process is repeated for the remaining seven motor covers.

This Ares Acres tutorial expands DJI’s installation video into a complete technician-facing workflow. It preserves the demonstrated sequence while adding power-isolation boundaries, hardware organization, connector verification, single-battery storage logic, spacer-orientation checks, torque discipline, firmware-upgrade precautions, troubleshooting, and U.S. regulatory context for large T100 lifting operations.

Quick Answer: How Do You Install the DJI T100 Lift System Dual Battery Version?

The four most consequential errors are energizing the aircraft during open electrical work, failing to seat the power-distribution connector until it clicks, reversing either propeller spacer, and tightening a propeller fastener without the specified blue adhesive and verified 150 kgf·cm torque.

Standard vs. Dual-Battery DJI T100 Lifting Systems

DJI publishes different ratings for the standard lifting system and the dual-battery lifting system. The dual-battery configuration should not be described as an automatic payload-capacity increase.

DJI T100 specification	Standard lifting system	Dual-battery lifting system
Listed system dimensions	805 × 764 × 669 mm	805 × 960 × 669 mm
Listed load capacity	100 kg	80 kg
Standard lifting-cable length	10 m	10 m
Recommended cable length	10–15 m	10–15 m
Listed operating temperature	0–40°C	0–40°C
Emergency escape mode	Refer to current configuration documentation	Cable fuse disconnection and escape
Aircraft weight in DJI specifications	65 kg with lifting system	90 kg with dual-battery lifting system
Listed maximum takeoff weight for lifting	165 kg	170 kg

These figures describe published system limits under DJI’s stated conditions. The DJI Agriculture app can recommend a lower loading weight based on aircraft condition, environment, altitude, temperature, battery state, and task. Never exceed the lowest applicable aircraft, system, authorization, manual, site, or operating limit. Review the current official DJI Agras T100 specifications before configuring a mission.

Why the Dual-Battery Installation Includes Motor Upper Covers

The installation is not limited to attaching a second battery path. DJI’s procedure replaces the front top shell, adds a power-distribution-board fixing bracket, revises cable storage near both battery sliders, and installs a new upper cover on every motor.

The motor-cover conversion must be treated as an eight-position aircraft-wide modification. Completing only one or several covers and then powering the aircraft creates an inconsistent configuration that has not followed the demonstrated procedure.

The propeller must be removed to access each upper cover, which means every motor position also becomes a propeller-installation task. Spacer direction, propeller position, clamp placement, blue adhesive, and final torque all become flight-critical verification points.

Installation Components & Required Tools

Components Identified in the DJI Procedure

• DJI Lift System Dual Battery Version;
• replacement front top shell;
• power-distribution-board fixing bracket;
• new motor upper covers for all eight positions;
• associated lifting flight platform and payload connection;
• required mounting hardware; and
• the approved blue adhesive or threadlocker specified by DJI.

Confirm the exact contents against the kit packing list. Do not begin installation if one motor cover, bracket, fastener, locating feature, or connector component is missing.

Tools Identified in the DJI Procedure

• 13 mm wrench for propeller fasteners;
• torque-capable 13 mm tool for final 150 kgf·cm tightening;
• M2.5 screwdriver for motor upper-cover screws; and
• the correct driver for power-distribution-board cover and top-shell screws.

Recommended Work-Control Materials

• eight labeled motor-position trays or bags;
• labels for propeller position and orientation;
• clean protective coverings;
• calibrated torque tool capable of approximately 14.7 N·m;
• DJI-specified blue adhesive or threadlocker;
• non-permanent marker or position labels;
• inspection light;
• lint-free cleaning materials; and
• the latest DJI installation and service documentation.

Do not substitute generic glue for the specified blue product. “Blue adhesive” in the source procedure should be treated as DJI’s specified removable thread-retention material and applied only at the location and quantity shown in the current instructions.

Before You Begin: Power Isolation & Propeller Safety

Aircraft State

• Land and stabilize the aircraft on a level service surface.
• Power the aircraft off completely.
• Remove every installed flight battery.
• Keep batteries away from the work area until all eight propeller assemblies are complete.
• Do not perform open-connector or propeller service with a battery installed.
• Prevent another technician from energizing the aircraft during the job.

Propeller Area

• Treat each propeller as position-specific unless DJI explicitly states otherwise.
• Mark the motor position and propeller orientation before removal.
• Keep hands and tools clear of propeller edges.
• Support the propeller so removing the fasteners does not bend or strike it.
• Never rotate a powered motor during installation.
• Inspect every propeller for cracks, delamination, deformation, impact marks, and contaminated mating surfaces.

Hardware Control

Use a separate labeled tray for each motor position. Keep its:

• two 13 mm fasteners;
• propeller clamp;
• upper spacer;
• propeller;
• lower spacer;
• four M2.5 cover screws; and
• original motor cover

together until that position is rebuilt and independently verified.

U.S. Regulatory Context: Part 107, Section 44807, Part 91 & Part 137

Installing the lift system does not determine the legal authority for the eventual flight. Aircraft weight and mission purpose matter.

Part 107 Does Not Independently Cover a T100 at or Above 55 Pounds

The FAA’s Part 107 guidance applies to small UAS weighing less than 55 pounds at takeoff. DJI’s published T100 weights are well above that threshold before a lifting load is added.

A Part 107 Remote Pilot Certificate may remain a pilot-qualification element in a specific exemption or authorization, but the aircraft is not converted into a Part 107 small UAS merely because the pilot holds that certificate.

Large T100 Operations Can Require Section 44807 and Part 91 Authority

The FAA explains that operators seeking to fly an aircraft above the Part 107 weight threshold may need authority under 49 U.S.C. §44807, together with the applicable exemption, registration, Part 91 conditions, COA, and operating limitations.

The operator must verify that the specific T100 configuration, dual-battery system, maximum weight, lifting mission, and aircraft identification are covered by the actual authorization.

Part 137 Depends on the Mission

Part 137 governs covered agricultural aircraft operations, particularly dispensing economic poisons or other agricultural materials and related operations within its definitions. Installing a lift system does not automatically make every lifting or delivery mission a Part 137 operation.

A lifting mission may instead implicate other large-UAS, external-load, cargo, hazardous-material, airspace, or operating requirements depending on what is carried, why it is carried, whether property is transported for compensation, and how the flight is conducted. The operator should obtain mission-specific regulatory guidance rather than treating “Part 107” or “Part 137” as a universal label.

This tutorial covers hardware installation, not legal authorization.

Step 1 — Unpack and Inventory the Dual-Battery Lift System

Take out the DJI Lift System Dual Battery Version and inventory its supplied components.

The source procedure specifically calls out:

• the replacement front top shell; and
• the power-distribution-board fixing bracket.

Also verify that the required new motor upper covers and related hardware are present for all eight positions before aircraft disassembly begins.

Compare every component with the packing list. Stop if there is shipping damage, a bent bracket, cracked shell, missing cover, damaged connector, or incomplete hardware.

Step 2 — Confirm the Aircraft Is Powered Off and Remove All Batteries

Before removing covers or touching the power-distribution board, power the T100 off and remove all installed batteries.

Physical battery removal is the electrical-isolation boundary. Do not rely solely on the power button while the power-distribution connector, payload cable, top shell, and propeller assemblies are being serviced.

Step 3 — Remove the Four Dustproof-Cover Screws

Unscrew the four screws securing the power-distribution-board dustproof cover on the T100 airframe.

Support the cover while removing the final screw. Place all four fasteners in a labeled tray and inspect them for damage or contamination.

Do not allow a screwdriver to slip into the power-distribution board or wiring area.

Step 4 — Remove the Power-Distribution-Board Dustproof Cover

Lift away the dustproof cover.

Keep the exposed power-distribution area clean and dry. Do not place loose screws, tools, threadlocker, or debris on the board. Inspect visible connectors and wiring for damage before continuing.

The cover must be reinstalled or replaced as required by the completed configuration before the aircraft returns to service.

Step 5 — Remove the Front Top-Shell Screws

Unscrew the fasteners securing the original front top shell.

Record screw locations if lengths or types differ. Do not assume every shell screw is interchangeable. Keep the shell hardware separate from the four dustproof-cover screws and all propeller hardware.

Step 6 — Remove the Original Front Top Shell

Remove the front top shell carefully.

Lift it without snagging wiring, connectors, brackets, or airframe features beneath it. Observe how the original shell seats and where its edges, tabs, and fasteners align.

Inspect the exposed area for:

• pinched wiring;
• damaged insulation;
• loose hardware;
• chemical contamination;
• dust or debris;
• cracked mounting points; or
• signs of heat or arcing.

Correct any abnormal condition before installing the replacement shell.

Step 7 — Install the New Front Top Shell

Reinstall the new front top shell in the reverse or specified assembly sequence.

Seat the shell evenly. All tabs, edges, holes, and interfaces should align without force. Do not use the screws to pull a misaligned shell into place.

Start the fasteners in their correct positions, then tighten them using DJI’s sequence and specified torque if provided. Confirm no wire is trapped beneath the shell.

Step 8 — Install the Power-Distribution-Board Fixing Bracket

Install the supplied power-distribution-board fixing bracket.

The bracket should sit in the intended orientation and support the connector arrangement without loading the board or wiring. Confirm:

• mounting holes align;
• bracket is fully seated;
• no wire lies underneath it;
• connector movement is not obstructed; and
• the dustproof-cover area remains compatible with the final assembly.

Step 9 — Position the Flight Platform on the Dual-Battery Lift System

Place the flight platform onto the DJI Lift System Dual Battery Version.

Support the platform during positioning. Do not allow its weight to hang from the payload cable or power-distribution connector.

Align the platform with the middle frame before closing any latch. A platform that is not fully seated can place abnormal load on the latch and cable interfaces.

Step 10 — Lock the Middle-Frame Latch

Close and lock the middle-frame latch.

Verify that it reaches the fully locked position and physically retains the platform. Do not accept a partially closed latch or one that requires excessive force because the platform is misaligned.

Step 11 — Connect the Payload Cable Interface

Connect the payload cable interface.

Align the connector and engage it fully. Handle the connector body rather than pulling or pushing on the wires.

Inspect for:

• bent or recessed pins;
• damaged seals;
• chemical residue;
• broken latch features; or
• wire strain.

Step 12 — Snap the Payload Cable Into Its Latch

Secure the payload cable interface in the dedicated latch.

The cable should be supported and restrained without being crushed, sharply bent, or held under tension. Confirm the latch is fully closed.

Step 13 — Insert the Power-Distribution Connector

Insert the power-distribution connector into the power-distribution board on the airframe.

Push it into the intended interface until it clicks firmly into place.

The click is an important engagement cue, but it should be paired with a visual and light pull-check. Do not pull on the wires. Confirm the connector housing is square, fully seated, and retained.

Dual-Battery Connection Check

Check	Required condition
Connector orientation	Matches the board interface without force.
Engagement	Connector seats completely and clicks.
Retention	Connector housing remains secure during a gentle verification.
Wire path	Wiring does not cross a battery-slider interference zone.
Bracket support	Fixing bracket supports the installed path without bending the board.
Dust protection	Final configuration restores required protection around the board.

Step 14 — Configure the Power Connector for Single-Battery Operation

When the aircraft will be used in a single-battery configuration, securely snap the power-distribution connector onto the landing-gear crossbeam as shown by DJI.

This is a storage and retention position. A loose connector can move, vibrate, strike another component, or interfere with the aircraft during flight.

Do not leave the unused connector hanging from its wiring.

Step 15 — Align Both Locating Pins

Confirm that both locating pins at the crossbeam storage position are fully aligned.

DJI specifically identifies correct pin alignment as a way to minimize the risk of connector disengagement during flight.

Verify:

• both pins enter their intended locating features;
• the connector sits flush;
• the retention mechanism is fully engaged;
• wiring is not twisted; and
• the stored connector cannot move freely.

Step 16 — Loosen the Power-Distribution Wiring Screws on One Side

Unscrew the designated fasteners on the power-distribution-board wiring so the wiring can be repositioned and will not interfere with insertion of a single battery.

Do not remove or loosen unrelated board hardware. Maintain battery removal and power isolation throughout this step.

Step 17 — Route the Wiring Behind the Battery Slider

Move the wiring behind the battery slider as demonstrated.

The goal is to clear the single-battery insertion path while protecting the wiring from pinch, abrasion, and slider movement.

Check that the wire:

• remains behind the intended slider area;
• does not cross a sharp edge;
• is not tensioned at the board connector;
• cannot enter the battery rail;
• does not obstruct the latch; and
• retains enough controlled slack for the approved configurations.

Step 18 — Repeat the Wiring Adjustment on the Other Side

Perform the same power-distribution wiring adjustment behind the battery slider on the opposite side.

Both sides must provide clear, symmetrical battery-insertion paths. Inspect the complete battery bay with no battery installed before continuing.

Single-Battery Clearance Inspection

Area	What to verify
Left battery slider	Wiring is behind the slider and outside the insertion path.
Right battery slider	Opposite-side wiring matches the intended routing.
Stored connector	Both locating pins are aligned on the crossbeam.
Battery rails	No wire, connector, screw, or bracket enters either rail.
Board connection	Wiring remains secure and is not pulled sideways.
Latches	Battery and platform latch areas are unobstructed.

Step 19 — Select and Label the First Motor Position

Begin the motor-cover conversion at one position and label it clearly.

Before loosening the propeller fasteners, record:

• motor position;
• propeller orientation;
• clamp orientation;
• upper-spacer direction;
• lower-spacer direction; and
• visible fastener arrangement.

Complete one motor before opening the next whenever practical. This reduces the risk of mixing propellers, spacers, clamps, and screws between positions.

Step 20 — Remove the Two Propeller Fasteners With a 13 mm Wrench

Using a 13 mm wrench, unscrew the two nuts or fasteners securing the propeller assembly at the selected motor position.

Hold the assembly securely and prevent unintended propeller rotation. Use the approved counter-hold method without loading the motor, shaft, or blades incorrectly.

Place both fasteners in the labeled tray for that motor.

Step 21 — Remove the Propeller Clamp

Lift off the propeller clamp.

Note its installed face and orientation. Inspect it for cracking, distortion, thread damage, fretting, or contamination.

Do not reuse a visibly damaged clamp.

Step 22 — Remove the Upper Propeller Spacer

Remove the spacer located above the propeller.

Record that this spacer’s protrusion must face downward when the assembly is rebuilt.

Keep it clean and inspect the mating surfaces. Do not invert or mix it with the lower spacer.

Step 23 — Remove the Propeller

Remove the propeller and keep it associated with the original motor position.

Inspect:

• blade surfaces;
• hub and mounting holes;
• leading and trailing edges;
• carbon-fiber condition;
• signs of impact or heat;
• deformation; and
• contamination on the mounting surfaces.

If the propeller is damaged or its position cannot be confirmed, stop and use the correct OEM replacement and DJI installation procedure.

Step 24 — Remove the Lower Propeller Spacer

Remove the spacer beneath the propeller if it has not already remained on the motor assembly.

Record that the lower spacer’s protrusion must face upward during reassembly.

The two spacer orientations oppose one another around the propeller:

Stack position	Required protrusion direction
Lower spacer, installed before propeller	Upward
Propeller	Installed in its correct motor position and orientation
Upper spacer, installed after propeller	Downward

Step 25 — Remove the Four Motor Upper-Cover Screws

Using an M2.5 screwdriver, remove the four screws securing the motor upper cover.

Apply the driver squarely to each screw to avoid stripping it. Keep all four screws in the labeled motor-position tray.

Do not allow loose screws to fall into the motor.

Step 26 — Remove the Original Motor Upper Cover

Lift away the original motor upper cover.

Inspect the exposed motor area without introducing dirt or metal debris. Do not touch or contaminate bearings, electrical components, or internal surfaces unnecessarily.

Compare the original cover with the new one before installation. Confirm the new cover matches the required position and kit revision.

Step 27 — Install the New Motor Upper Cover

Place the new motor upper cover onto the motor.

Align all four mounting holes and confirm the cover sits flush without force. The cover should not trap a wire, contact a rotating component, or rock on the motor housing.

Step 28 — Tighten the Four Motor-Cover Screws

Using the M2.5 screwdriver, reinstall and tighten the four motor upper-cover screws.

Start all four correctly before final seating when the design allows. Tighten in an even pattern using DJI’s specified method and torque if supplied.

Verify the cover is stable and evenly seated.

Step 29 — Install the Lower Propeller Spacer With Protrusion Up

Install the first or lower propeller spacer.

The protrusion must face upward toward the propeller.

Pause and verify the direction visually and by touch before placing the propeller over it.

Step 30 — Reinstall the Correct Propeller

Return the original verified propeller to its correct motor position and orientation.

Align it with the spacer and mounting features without force. Do not substitute a propeller from another position merely because it appears similar.

Step 31 — Install the Upper Propeller Spacer With Protrusion Down

Install the second or upper spacer above the propeller.

The protrusion must face downward toward the propeller.

The correct stack is:

1. lower spacer—protrusion up;
2. propeller;
3. upper spacer—protrusion down; and
4. propeller clamp.

Both spacer protrusions therefore face inward toward the propeller.

Step 32 — Install the Propeller Clamp

Place the propeller clamp over the upper spacer in its original orientation.

Confirm that the clamp sits flat and the propeller remains centered. Do not use the fasteners to pull a misaligned stack together.

Step 33 — Apply the Specified Blue Adhesive to the Motor Shaft

Apply the blue adhesive or thread-retention product to the motor shaft at the location shown by DJI.

Use only the specified product and amount. Avoid excess material that could migrate toward bearings, spacers, the propeller, or other surfaces.

Do not apply:

• generic permanent adhesive;
• an unknown-strength threadlocker;
• contaminated or expired product; or
• more material than the current DJI procedure specifies.

Step 34 — Reinstall and Tighten the Propeller Fasteners

Install the propeller fasteners and use the 13 mm tool to tighten them.

DJI’s tutorial gives a recommended torque of 150 kgf·cm, which is approximately 14.7 N·m.

Use a calibrated torque tool. Tighten with the correct approved pattern and counter-hold method. Do not estimate final torque by feel.

Torque Conversion

Original DJI value	Approximate SI conversion	Application
150 kgf·cm	14.7 N·m	Propeller mounting fasteners in the demonstrated installation

The original DJI value remains the controlling reference. Confirm current service documentation in case a later kit or hardware revision specifies a different method.

Step 35 — Audit the Completed Motor Position

Before moving to the next motor, verify:

• new upper cover installed;
• all four M2.5 cover screws present;
• lower spacer protrusion up;
• correct propeller installed;
• upper spacer protrusion down;
• clamp seated correctly;
• blue adhesive applied as specified;
• both propeller fasteners installed;
• final torque recorded; and
• no tool or loose hardware remains near the motor.

Mark the position complete only after this audit.

Step 36 — Repeat for the Remaining Seven Motor Covers

Repeat the complete propeller-removal, motor-cover replacement, propeller-stack reconstruction, adhesive, and torque process for the remaining seven motor covers.

Do not shorten the process after the first position. Each motor requires the same independent verification.

A useful control sheet contains eight rows:

Motor position	Cover screws ×4	Lower spacer up	Propeller verified	Upper spacer down	Blue adhesive	150 kgf·cm	Inspector
1	□	□	□	□	□	□	□
2	□	□	□	□	□	□	□
3	□	□	□	□	□	□	□
4	□	□	□	□	□	□	□
5	□	□	□	□	□	□	□
6	□	□	□	□	□	□	□
7	□	□	□	□	□	□	□
8	□	□	□	□	□	□	□

Step 37 — Perform a Complete Eight-Motor Propeller Audit

After all positions are complete, inspect the aircraft as one system.

Confirm:

• eight new motor upper covers are installed;
• 32 upper-cover screws are present if the demonstrated four-per-cover arrangement applies to all eight;
• every propeller returned to its correct position;
• every lower spacer faces up;
• every upper spacer faces down;
• every clamp is seated;
• every required fastener received the specified blue product;
• every propeller-fastener set was torqued to the current specification; and
• no propeller contacts a cover or adjacent component during careful unpowered inspection.

If any motor position cannot be positively verified, reopen and inspect it before battery installation.

Step 38 — Reinspect the Power-Distribution and Battery Areas

Before installing a battery, return to the central frame and confirm:

• new front top shell is secure;
• power-distribution-board fixing bracket is installed;
• dustproof protection is restored as specified;
• lifting platform is fully seated;
• middle-frame latch is locked;
• payload cable is connected and latched;
• dual-battery power connector is fully clicked into place when used;
• single-battery storage connector is secured to both locating pins when applicable;
• wiring is behind both battery sliders; and
• neither battery insertion path contains a wire, fastener, bracket, or connector.

Step 39 — Insert the Battery

Insert the approved battery configuration only after every battery-removed inspection passes.

Observe the battery slider and wiring while inserting. Stop if the battery contacts, pushes, or traps a cable. Do not force the battery past resistance.

Confirm each installed battery is fully seated and latched according to the current DJI procedure.

Step 40 — Power On the Aircraft

Power on the aircraft in a controlled service area with all people clear of propellers and the lifting mechanism.

Watch for:

• power-distribution errors;
• payload communication errors;
• battery recognition errors;
• motor or ESC warnings;
• lift-system alerts;
• unexpected heat, smell, sound, or vibration; and
• firmware-update prompts.

Power down immediately if the installation produces an abnormal electrical or mechanical condition.

Step 41 — Upgrade Firmware Through the Remote Controller App

Follow the prompts in the remote controller app to upgrade the required firmware.

During the update:

• use batteries with adequate charge;
• keep the aircraft and controller powered;
• maintain the required communication or network connection;
• do not disconnect the payload cable;
• do not remove a battery;
• do not close or interrupt the app; and
• wait for confirmed completion on all required components.

After the update, restart components only as directed and confirm the controller no longer reports an incomplete upgrade.

Step 42 — Complete Post-Installation Recognition and Function Checks

Verify that the aircraft recognizes:

• the intended battery configuration;
• the lift system;
• the flight platform;
• the payload interface;
• the power-distribution system; and
• all updated firmware components.

Do not attach a lifting load for the first power-on check. Complete DJI’s required calibration, no-load inspection, and functional test before a loaded operation.

Single-Battery vs. Dual-Battery Connector Configuration

Operating configuration	Connector position	Critical check
Dual battery	Inserted into power-distribution board on airframe	Fully seated with a firm click and supported by the fixing bracket.
Single battery	Snapped onto landing-gear crossbeam	Both locating pins fully aligned so the connector cannot disengage during flight.
Either configuration	Wiring behind both battery sliders	No wire can interfere with battery insertion, rails, or latches.

Do not change between configurations by memory alone. Use the current DJI procedure and recheck the connector, locating pins, wiring, battery rails, and app recognition every time the configuration changes.

Propeller Stack Orientation Guide

Installation order	Component	Direction or check
1	Lower propeller spacer	Protrusion faces upward.
2	Propeller	Correct original motor position and rotation orientation.
3	Upper propeller spacer	Protrusion faces downward.
4	Propeller clamp	Sits flat and centered.
5	Blue adhesive	DJI-specified type, quantity, and location.
6	Two 13 mm fasteners	Tightened to recommended 150 kgf·cm using calibrated tooling.

The spacer protrusions face inward toward the propeller. This simple verbal check can prevent an inverted stack, but it does not replace visual comparison with DJI’s current diagram.

Common Dual-Battery Lift-System Installation Mistakes

1. Working With a Battery Installed

Open power-distribution and motor work requires physical battery removal, not only a powered-off display.

2. Leaving Hardware Inside the Power-Distribution Area

Account for every cover and shell screw before closing the aircraft.

3. Pulling the New Top Shell Into Alignment With Screws

The shell should seat naturally. Correct wiring or tab interference before tightening.

4. Omitting the Power-Distribution-Board Fixing Bracket

The bracket is a required component of the demonstrated conversion.

5. Failing to Lock the Middle-Frame Latch

Platform placement is not complete until the latch is fully locked.

6. Connecting the Payload Cable Without Securing Its Latch

The connector and cable-retention latch are separate checks.

7. Assuming the Power Connector Is Seated Without Hearing or Feeling the Click

Insert it fully and verify retention at the connector housing.

8. Leaving the Single-Battery Connector Loose

Snap it onto the landing-gear crossbeam and align both locating pins.

9. Routing PDB Wiring in Front of a Battery Slider

Move the wiring behind both sliders to avoid battery-insertion interference.

10. Mixing Propellers or Spacers Between Motors

Label every motor position and complete one assembly at a time.

11. Removing Propeller Fasteners With an Incorrect Tool

Use the specified 13 mm tool and an approved counter-hold method.

12. Dropping an M2.5 Screw Into the Motor

Control each fastener and account for all four at every position.

13. Installing Only Some of the New Motor Covers

The demonstrated procedure repeats across the remaining seven after the first—eight total positions.

14. Reversing the Lower Spacer

Its protrusion must face upward toward the propeller.

15. Reversing the Upper Spacer

Its protrusion must face downward toward the propeller.

16. Applying the Wrong Adhesive

Use only DJI’s specified blue thread-retention material.

17. Allowing Adhesive to Reach Bearings or Mating Surfaces

Apply only the specified quantity and location.

18. Estimating 150 kgf·cm by Feel

Use a calibrated torque tool capable of approximately 14.7 N·m.

19. Failing to Record All Eight Torque Checks

An eight-position checklist prevents an unfinished assembly from being overlooked.

20. Inserting a Battery Over Misrouted Wiring

Stop at resistance and inspect both slider paths.

21. Interrupting the Firmware Upgrade

Maintain power and connection until the controller confirms completion.

22. Testing First With a Suspended Load

Complete recognition, firmware, calibration, and no-load checks first.

Troubleshooting the Dual-Battery Installation

Problem	Likely cause	What to inspect

FAQ: DJI T100 Lift System Dual Battery Version Installation

What does the dual-battery installation change?

It adds the dual-battery lifting configuration, replaces the front top shell, adds a power-distribution-board fixing bracket, changes battery-area wiring and connector storage, and replaces the upper motor covers across all eight positions.

Does dual battery mean the T100 can lift more weight?

Not according to DJI’s published specifications. DJI lists 100 kg capacity for the standard lifting system and 80 kg for the dual-battery lifting system. Use the current app recommendation and the lowest applicable limit.

What is DJI’s listed dual-battery lifting-system maximum takeoff weight?

DJI lists 170 kg maximum takeoff weight for the dual-battery lifting configuration under its stated conditions.

Should batteries be removed during installation?

Yes. Remove every battery before opening the power-distribution area, moving wiring, connecting the payload, or servicing propellers and motor covers.

How many screws secure the PDB dustproof cover?

Four screws secure the dustproof cover in the demonstrated procedure.

What shell is replaced?

The original front top shell is removed and the new front top shell supplied for the conversion is installed.

What bracket must be installed?

Install the power-distribution-board fixing bracket supplied with the kit.

What secures the lifting flight platform?

Place the platform on the dual-battery lift system and lock the middle-frame latch.

How is the payload cable secured?

Connect the payload cable interface, then snap the cable or interface into its dedicated latch.

How do I know the power-distribution connector is seated?

DJI instructs the installer to push it into the power-distribution board until it clicks firmly into place. Pair the click with visual and retention checks.

Where does the connector go during single-battery operation?

Snap it securely onto the landing-gear crossbeam and fully align both locating pins.

Why are the locating pins important?

DJI states that full alignment helps minimize the risk of connector disengagement during flight.

Why is PDB wiring moved behind the battery sliders?

The new routing prevents the wiring from interfering with insertion of a single battery. Perform the adjustment on both sides.

What tool removes the propeller fasteners?

Use a 13 mm wrench with the approved counter-hold procedure.

In what order is the propeller removed?

After removing the two fasteners, remove the propeller clamp, upper spacer, propeller, and lower spacer while preserving the position and orientation of each component.

What tool removes the motor upper cover?

Use an M2.5 screwdriver to remove its four mounting screws.

How many motor upper covers are replaced?

Eight total—the first demonstrated position plus the remaining seven.

Which way does the lower propeller spacer face?

Its protrusion faces upward toward the propeller.

Which way does the upper propeller spacer face?

Its protrusion faces downward toward the propeller.

Where do the spacer protrusions point?

Both point inward toward the propeller—lower spacer up and upper spacer down.

What is the blue adhesive?

Treat it as the DJI-specified blue thread-retention product for the motor-shaft or propeller-fastener assembly. Do not substitute unknown or permanent glue.

What torque does DJI recommend?

The tutorial specifies 150 kgf·cm, approximately 14.7 N·m, for the propeller mounting fasteners.

Can I tighten the propellers by feel?

No. Use a calibrated torque tool and the current DJI specification.

Should I power on before all eight motor covers are complete?

No. Complete and audit the entire conversion before battery installation and power-on.

What happens after the battery is installed?

Power on in a controlled area and follow the remote controller app prompts to upgrade the required firmware.

Can I interrupt the firmware upgrade?

No. Maintain adequate power and the required connection until the app confirms completion.

Should the first test use a suspended load?

No. Verify recognition, firmware, calibration, motor condition, and lift-system behavior through DJI’s required no-load checks first.

Does FAA Part 107 alone authorize this T100 configuration?

No. Part 107 generally applies to UAS weighing less than 55 pounds at takeoff. A T100 lifting configuration requires the large-UAS authority applicable to the aircraft and mission, which may include Section 44807, Part 91 conditions, registration, and a COA or other approvals.

Does every lifting mission require Part 137?

Not automatically. Part 137 applies when the mission meets its agricultural-aircraft-operation definitions. Lifting, transport, or delivery can implicate a different or additional regulatory pathway depending on the cargo, purpose, weight, compensation, and operating concept.

What should be checked before the first flight?

Verify all eight propeller stacks and torque records, motor covers, front shell, PDB protection, bracket, platform latch, payload connector, selected battery configuration, locating pins, battery-slider wiring, firmware, aircraft warnings, lift-system calibration, rigging, load, operating area, and authorization.

Final Takeaway

The DJI Agras T100 Lift System Dual Battery Version is an aircraft-wide conversion, not a simple battery accessory. The front top shell and power-distribution area are modified, the lifting flight platform and payload connection must be locked correctly, and the connector and wiring must support both dual-battery use and the designated single-battery storage arrangement.

The motor-cover portion is equally important. All eight upper covers must be replaced. Every propeller stack must be reconstructed with the lower spacer protrusion facing upward and the upper spacer protrusion facing downward. DJI’s specified blue adhesive must be applied correctly, and the propeller fasteners must be tightened to the recommended 150 kgf·cm—approximately 14.7 N·m—with calibrated tooling.

Only after an eight-position audit, complete power-distribution and battery-slider inspection, controlled power-on, firmware upgrade, component recognition, calibration, and no-load test should the aircraft be considered for a lifting operation. The eventual mission must also fall within the operator’s actual large-UAS, airspace, cargo, external-load, and—when applicable—Part 137 authority.

Installation and regulatory note: Kit contents, motor-cover design, fasteners, torque values, thread-retention material, connector routing, firmware, calibration, and supported battery configurations can vary by hardware revision, aircraft configuration, DJI Agriculture app version, firmware, and region. Verify compatibility and follow the latest official DJI installation and service documentation. Keep all batteries removed during mechanical and electrical work unless an official diagnostic procedure explicitly requires otherwise. A Part 107 pilot certificate does not by itself authorize operation of a T100 at or above 55 pounds. Verify the specific aircraft, battery configuration, payload, cargo, rigging, exemption, registration, Part 91 conditions, COA, airspace, Part 137 applicability, state and local requirements, and all operating limitations before flight.
