🔧 Component Overview

The DJI Agras T100 / T70P Original ESC Module is a core flight-critical component responsible for regulating power delivery between the battery system and the propulsion motors. Every takeoff, climb, turn, and payload-loaded maneuver depends on precise ESC performance.

When an ESC fails, the aircraft does not "limp along" — it grounds the mission entirely. For commercial operators, this is not a part you replace reactively. It is a required spare for protecting uptime and revenue.

The first question on any propulsion fault is whether the problem follows the position or follows the part. Note which arm the aircraft reports, then move the suspect module to a known good position, or move a known good motor onto the suspect arm, and fly or bench test again. If the fault stays on the arm after the motor has been changed, it is upstream of the motor. If the fault travels with the module, you have your answer without guessing. Do this before ordering, because a motor short and a controller failure produce near identical complaints from the cockpit.

Clear the motor before you condemn the controller. With the aircraft powered down and the phase leads disconnected, turn the motor by hand and feel for notchiness, drag, or grit, which is a bearing telling you it has ingested dust and chemical. Then compare the three phase leads against one another for balance and check each of them against the motor case. A phase that reads plainly different from the other two, or any continuity between a winding and the case, condemns the motor. Fitting a controller to a shorted motor destroys the controller, often on the first loaded flight.

Read heat rather than absolute numbers. Every position on the aircraft is doing similar work, so the useful signal is the spread between them at the same throttle and the same moment, not whether one figure looks high. A single position that consistently runs above its siblings under the same load has either a compromised heat path, a partially shorted motor drawing more current, or a switching stage on the way out. All four positions running hot together on a heavy tank in July is the machine telling you about the day, not about a module.

Look at the module and its connections with the arm open. Brown or black discoloration around a terminal, a chalky or scorched smell, melted insulation at the phase leads, a swollen or vented capacitor, or a board that has been sitting in dried spray residue all point at where the energy went. Pay particular attention to the phase and power connections themselves, because a loose or corroded joint builds resistance, then heat, then a failure that looks exactly like a controller fault while the controller was only ever the victim.

⚙️ Functional Purpose

The ESC module manages:

• Motor speed control under heavy payload loads
• Smooth power modulation during spray, spread, and hover operations
• Thermal regulation under sustained high-current draw
• Communication between the flight controller and propulsion system

Treat the power side as live until you have proved otherwise. Batteries out, and give the aircraft time before you go into the arm, because the bus capacitance on a heavy lift propulsion system does not discharge the instant the pack is unplugged. Never let a tool bridge a power terminal to structure. Then photograph the arm exactly as it sits, and label the phase leads before a single one comes off, because motor rotation direction depends on how those three land and getting it wrong is discovered at spin up with propellers fitted.

Support the arm and lift the module by its body, not by its wires. Note every fastener, spacer, and clip as it comes out and which face of each sat against what. If the module seats against a heat sinking surface with a pad or compound between them, that path is the only way it sheds heat under sustained current, so note what is there and plan to renew it rather than reuse a torn pad or a face contaminated with dust and dried chemical. Wipe both surfaces clean before anything goes back together.

On refit, restore the factory routing exactly and keep every conductor clear of clamp edges and moving structure. Seat each connector until it latches and then tug lightly on the housing rather than the wire to prove it. Bring fasteners up evenly to the DJI figure for your airframe with a calibrated driver, since a module that is bolted down unevenly does not make full contact with its heat path and a module that is crushed down cracks its own board. You know it is right when the module sits flat, nothing is pinched, and no lead is under tension.

Verify in stages before you trust it with a tank. With the propellers off, power up and confirm the aircraft arms without a propulsion or communication warning, and watch that the motor accelerates smoothly rather than stumbling as it comes off zero. Confirm the direction of rotation matches what the original did before the blades go back on. Then work up through a light hover to a loaded test, watching the temperature spread across positions rather than one figure, and listening for any position that sounds different from the others.

⚠️ Common Replacement Indicators

• Motor desync or hesitation
• ESC overheating warnings
• Inconsistent thrust output
• Sudden motor shutdowns under load

When these symptoms appear, replacement is not optional — it is operationally necessary.

One motor stutters or hesitates as it comes off idle but pulls cleanly at working speed: a timing or commutation problem at low rpm, where the controller has the least information to work with. This is a classic early controller symptom and it tends to get worse in the cold, which is why operators notice it first on an early morning start.

The aircraft holds a consistent yaw or drifts to one side under load and needs constant correction, with no propeller damage and no obvious mechanical fault: one position is not producing the thrust that is being asked of it. The flight controller compensates and hides it until the compensation runs out, usually with a full tank in wind.

A thermal warning on one arm only, on a mild day, on a job the aircraft has flown many times: this is the module telling you its heat path or its switching stage has changed. Do not clear it and carry on. A thermal event is a symptom of current going somewhere it should not, and the next stage of that story is a shutdown in flight.

A motor that shuts down and restarts in flight, or that cuts under a hard climb with a full tank: a protection trip or a loss of sync under peak current. The aircraft may recover and finish the pass, which makes it tempting to treat as a glitch. It is not a glitch, it is the highest severity warning this component gives before it stops giving warnings.

A burnt or acrid smell around an arm after a flight, or fine soot deposited inside the arm: something has already overheated in there. Find it on the ground rather than in the air. A module that has been through a thermal event has stressed semiconductors and solder joints whether or not it still functions, and it will fail again at the worst possible moment.

A replacement module that fails again within a few flights: the original cause was never found. Look hard at the motor on that position for a shorted winding, at the phase and power connections for a high resistance joint that builds heat, and at the propeller for damage or imbalance driving vibration and current spikes back into the controller.

📐 Specifications

• Component Type: Electronic Speed Controller (ESC)
• Function: Motor power regulation & control
• Compatibility: DJI Agras T100 / T70P
• Installation Area: Aircraft arm / propulsion system
• SKU: BC.AG.SS001022.01
• Condition: Original DJI OEM component

Inspect before installation:

• Keep the ESC in its protective packaging until installation
• Inspect the motor, arm wiring, and connectors — a failed ESC often has an upstream or downstream cause
• Check for heat marks or burnt smell at the old ESC's mounting area

After installation:

• Verify solid connector seating and correct wiring per factory routing
• Power up and confirm no ESC communication or thermal warnings at idle
• Run an unloaded hover test, then a loaded test, watching thrust symmetry and temperatures

Voltage range, continuous and peak current, switching frequency, and thermal limits: Not published by DJI in the public parts documentation for this module. Do not select or substitute by electrical rating. Match DJI material number BC.AG.SS001022.01 against the label on the module you removed or the parts diagram for your airframe.

Motor: Not included. The controller and the motor on a position fail together often enough that both should be judged before either is ordered, and a motor with a shorted winding will take a new controller with it.

Thermal interface material: Not supplied as a separate item. If the module seats against a heat sinking surface with a pad or compound, plan on renewing that interface rather than reusing a pad that has been compressed, torn, or contaminated.

Repair options: None. A controller that has been through a thermal event, taken water, or shows a scorched terminal is replaced. Reflowing a joint or cleaning a board restores appearance without restoring the semiconductors that were stressed.

Substitution: Do not fit a general purpose or hobby grade speed controller. The module communicates with the flight controller, reports its own status and temperature, and is matched to the propulsion set, and none of that survives a substitution that merely spins the motor.

🧰 Fitment Verification Before You Order

This listing is DJI material number BC.AG.SS001022.01. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T100. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the ESC Module is easier to fit correctly when you can see how the original sat.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

This ESC module is necessary inventory, not optional stock, for:

• Commercial drone pilots operating under FAA Part 137
• Farms running multi-field, high-payload spray missions
• Contractors with revenue-dependent uptime requirements
• Service centers maintaining Agras T100 / T70P fleets
• Operators who cannot afford aircraft-down events mid-season

Experienced operators do not wait for ESC failure. They stage replacements in advance.

Recovering a propulsion position that has thrown desync, thermal, or communication warnings, where the aircraft is technically still flying but is doing so with one channel that has already told the operator it is unreliable under load.

Rebuilding a propulsion position after a motor failure, where the winding shorted and took the controller with it, and where replacing only the motor leaves the damaged half of a matched pair still installed on the aircraft.

Restoring thrust symmetry on an airframe that has started fighting the operator with a full tank, where the flight controller has been quietly compensating for one position that no longer delivers the thrust it is being asked for.

Holding a staged spare for a fleet flying heavy payload work in hot conditions, where thermal cycling is the dominant wear mechanism and the failure, when it arrives, arrives at the peak of the season rather than in the quiet months.

💡 Why This Part Matters

ESC failure is one of the highest-impact single-point failures on an agricultural drone. It can:

• Instantly ground an aircraft
• Risk secondary motor or avionics damage
• Cause missed spray windows and lost contracts

Replacing the ESC early preserves motor health, battery efficiency, flight stability, and long-term fleet reliability. This is a protect-the-asset component — not a convenience purchase.

Regulate the power. Steady the thrust. Stage the spare. Never lose a season to one controller.

Heat, not hours, is what ages a speed controller. Every switching device inside it expands and contracts with each load cycle, and heavy lift agricultural work is an unusually punishing duty cycle: sustained high current at low airspeed, high ambient temperatures, dust that insulates surfaces meant to shed heat, and a full tank on every takeoff. That is why two identical aircraft can show very different controller life, and why the operator who keeps heat paths clean gets more seasons out of the same part.

This is a component where the failure mode matters more than the failure rate. Most parts on an agricultural aircraft degrade in a way that gives an operator options: reduced flow, shorter flights, a warning to work around. A propulsion channel that drops under load does not offer that. It changes the aircraft's controllability in a moment, with a payload aboard, usually at the point in the pass where the aircraft is working hardest, which is exactly why this is a staged spare rather than a reactive purchase.

The controller also protects everything around it. It manages how current is delivered to the motor, which sets how hard the motor windings and bearings are worked and how much ripple the battery pack sees. A controller that is drifting out of tolerance quietly raises the cost of every flight elsewhere on the aircraft, shortening motor and pack life while the operator is still calling the aircraft serviceable. Replacing it on evidence rather than on failure keeps that hidden bill from being paid.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 / T70P ESC Module? It is the electronic speed controller that regulates power delivery between the battery system and a propulsion motor on the DJI Agras T100 and T70P — managing motor speed under heavy payload, smoothing power modulation during spray, spread, and hover work, regulating its own temperature under sustained high-current draw, and carrying communication between the flight controller and the propulsion system.

What is motor desync on an agricultural drone? Desync is when the controller loses its lock on the motor's rotation and can no longer time power delivery correctly — it shows up as hesitation or stutter under command, or a sudden motor shutdown under load, and it is one of the clearest ESC-side symptoms on this module's replacement-indicator list.

What are the signs a DJI Agras ESC needs replacing? Motor desync or hesitation, ESC overheating warnings, inconsistent thrust output, and sudden motor shutdowns under load.

What should be checked before installing a new ESC? Inspect the motor, arm wiring, and connectors on that position — a failed ESC often has an upstream or downstream cause — and check the old ESC's mounting area for heat marks or a burnt smell. Fitting a new controller without finding what stressed the old one risks repeating the failure.

How is a new ESC verified after installation? Confirm solid connector seating and factory wire routing, power up and check for no ESC communication or thermal warnings at idle, then run an unloaded hover test followed by a loaded test while watching thrust symmetry and temperatures.

Does this ESC have a DJI part number? Yes — BC.AG.SS001022.01, a DJI official SKU used across Agras heavy-lift platforms, supplied here as a single OEM module with factory-spec connector interfaces requiring no modification.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T100. Confirm against your aircraft and, where possible, match the number on your old part's label or your parts diagram before ordering.

How do I know my esc module needs replacing? The indicators operators most often report are: motor desync or hesitation; esc overheating warnings; inconsistent thrust output; sudden motor shutdowns under load. Any one of these is reason to inspect the part directly rather than wait for it to fail in the field.

Where can U.S. operators buy a DJI Agras T100 / T70P ESC? Ares Acres LLC, a U.S.-based authorized DJI Agras reseller, stocks the original ESC Module (BC.AG.SS001022.01) with free, fast shipping for all U.S. customers and same-day shipping with tracking on in-stock parts.

Is this a genuine DJI OEM ESC Module?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T100. Confirm by matching DJI material number BC.AG.SS001022.01 against the label on your original part or your model's DJI Agras parts diagram. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the ESC Module myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

How do I tell an ESC fault from a motor fault on the same arm?

Separate them mechanically before you separate them electrically. Turn the motor by hand with the phase leads off and feel for notchiness or drag, then compare the three phase leads for balance and check each against the motor case for a short. A bad motor usually reveals itself right there. If the motor checks out and the fault stays on that arm after swapping a known good motor onto it, the controller is what is left.

My replacement ESC failed within a few flights. What did I miss?

Almost always the thing that killed the first one. The usual candidates are a motor with a partially shorted winding, a loose or corroded phase or power connection building resistance and heat, a compromised heat path where the module sheds its heat, or a damaged or unbalanced propeller driving current spikes. Fit a controller to any of those and the new part inherits the same fault. Find the cause before the second module goes in.

One arm runs hotter than the others. Does that mean the ESC is failing?

It means something on that position is doing more work or shedding less heat than its siblings, and the module is one of three or four candidates. Check the heat path first, including the mounting faces and any interface material, then the motor for extra current draw, then the propeller for damage. If those are clean and the position still runs hot at the same throttle as the others, the module itself is the remaining explanation.

Can I finish the season with an occasional desync or shutdown warning?

This is the one warning not to schedule around. A loss of sync or a protection trip is the component reporting that it lost control of the motor under load, and it happens at peak current, meaning heavy tank, hard climb, or a turn at the end of a pass. Occasional means it is intermittent, not that it is mild. Ground the aircraft, find the cause, and fly it again once the position has been proved.

Does an ESC failure damage the motor, or the other way around?

Both directions happen, which is why they are inspected as a pair. A motor with a shorted or degraded winding presents an abnormal load and can destroy a controller, and a controller that is switching badly can overheat windings and hammer bearings. Whichever failed, examine the other before ordering, and expect that a position that has had a hard failure needs both parts rather than one.

Is there anything to configure, calibrate, or bind on a replacement module?

There is no throttle range calibration to perform in the way there is on hobby equipment; the module talks to the flight controller as part of a matched propulsion system. Follow the DJI service documentation for your airframe, and if it calls for a firmware check or a propulsion self test after a module is replaced, run it and treat a check that will not complete as a real finding rather than a software annoyance.
