DJI Agras T20 OEM Battery Interface Board

The DJI Agras T20 OEM Battery Interface Board is the aircraft-side circuit board that the flight battery connects to on the DJI Agras T20 and T16 spray aircraft. It is the aircraft's half of the battery connection: the battery's connector mates with the board's row of large power contact pins, power passes through the board to its three square metal terminal pads, and a short multi-wire lead carries the signal side of the connection into the aircraft. It belongs to the power system, it is identified for the DJI Agras T20 and T16, and it is supplied brand new as a single black board, as shown in the product images. Operators usually look for it as a T20 battery interface board, a T16 battery socket board, a T16 T20 battery connector board or an Agras T20 battery port after a battery that will not seat or will not be recognised, a power cut on landing or take-off, or a burnt or damaged contact in the battery bay. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × DJI Agras T20 OEM Battery Interface Board, with its attached multi-wire signal lead, as shown in the product images

One board. The board is the aircraft half of the battery connection. It is not a battery, not a charger, and not a battery connector plug for a pack.

What is part of the board: the black circuit board, its row of large power contact pins in their moulded shroud, the three square metal terminal pads, and the short multi-wire signal lead with its small connector. These come with the board because they are the board.

Not included: the flight battery, the power cables that fasten to the terminal pads, terminal screws or nuts, mounting screws, the battery bay housing or latch, and any other circuit board in the aircraft. Each of these is a separate part or stays with the aircraft.

Nothing is included because it appears in a photograph. If an image shows anything not named above, it is not part of the board.

🔧 Component Overview

Every flight on the Agras T20 and T16 starts at one joint: the battery sliding into its bay and its connector meeting the aircraft. The battery interface board is the aircraft side of that joint. Every amp that lifts the aircraft passes through it, and the battery's signal connection reaches the aircraft through it.

As shown in the product images, the board is a black circuit board with three working areas:

• The contact-pin row — a row of large power contact pins inside a black moulded shroud, where the battery's connector mates
• The three terminal pads — square metal pads, each with a central hole, where the aircraft's power cables fasten to the board; one carries a printed polarity mark
• The signal lead — a short bundle of fine wires leaving the board and ending in a small connector

The board also carries small components, printed markings and mounting holes at its edges, where it fixes in the battery bay.

Where it sits and what it touches:

• Position: the battery bay, facing the battery's connector
• On one side: the flight battery, through the contact-pin row
• On the other side: the aircraft's power cables at the three terminal pads, and the aircraft's electronics through the signal lead
• System: power, between the battery and everything the battery feeds

A battery interface board on a spray aircraft is plugged and unplugged more than almost any other part on the aircraft. Over a season it sees:

• Hundreds of battery insertions and removals, often in a hurry between sorties
• Full flight current through its pins on every take-off with a loaded tank
• Heat at the contacts when a battery is not fully seated
• Dust, sand and chaff carried into the bay on battery cases
• Spray residue and rinse water that find their way into the battery bay
• Side loads when a battery is rocked or forced into the bay
• Vibration through the frame on every flight

Boards in this position are usually replaced for one of a handful of reasons: pitted, burnt or heat-darkened contact pins, a cracked shroud or a pin pushed out of line, a damaged terminal pad, a damaged signal lead, or corrosion after liquid has reached the battery bay.

---

⚙️ Functional Purpose

The board's engineering role is connection. It gives the battery a fixed, aligned set of contacts to mate with, carries flight current from those contacts to the aircraft's power cables, and passes the signal side of the battery connection into the aircraft.

In the power system it:

• Receives the battery's connector in its contact-pin row
• Carries flight current from the pins to the three terminal pads
• Holds the aircraft's power cables at fixed, bolted points
• Passes signals between the battery and the aircraft through its multi-wire lead
• Holds the contacts in line so every battery meets them the same way

Because every amp passes through it, the board's condition shows up as the aircraft's condition. A contact that has lost its grip or its surface does not always stop a flight. It shows up as heat, as a battery that is reported oddly, or as a power interruption at the worst moment: under the load of a take-off with a full tank.

What the board does not do matters as much:

• It does not store energy; the battery does
• It does not charge the battery; the charger does
• It does not decide whether a battery is healthy; the battery reports its own state
• It does not distribute power to the motors on its own; the aircraft's power wiring beyond its terminals does
• It does not latch the battery in place; the battery bay and its latch do

🔍 Diagnosis — one aircraft with every battery, or one battery with every aircraft

A battery fault is reported as a battery fault. The pack will not be recognised, the reading looks wrong, or power drops under load, and the obvious move is to blame the pack and set it aside. Packs are the expensive item, and they are the thing the operator handles, so they take the blame first.

But the battery connection has two halves. The pack carries one. The aircraft carries the other, on this board. A worn, burnt or misaligned contact on the board produces the same symptoms as a failing pack, and it does it with every pack you put in.

Cross the fault before you condemn anything. Most operators run several packs and many run more than one aircraft. That makes the test free:

• One battery faults on every aircraft: the battery is the problem
• Every battery faults on one aircraft: the aircraft side of the connection is the suspect, and this board is the first part of it
• One battery faults on one aircraft only: look at both halves of that pairing, the pack's connector and the board's pins

Signs that point at the board:

• Pitted, darkened or heat-marked contact pins
• A pin that sits lower, higher or out of line compared with its neighbours
• A cracked or melted shroud around the pin row
• Heat at the battery bay after flight that other aircraft do not show
• A battery that has to be pushed or rocked before it is recognised
• Corrosion or residue on the pins or terminal pads after liquid has reached the bay
• A damaged, pinched or chafed signal lead

Clear these first, because they imitate a bad board:

• A battery not fully seated or latched: a partly inserted pack makes poor contact on a healthy board
• Debris in the bay: sand or chaff on the pins holds the battery off its contacts; clean and retest
• A loose terminal fastening: a power cable that is not tight at its pad behaves like a failing contact
• The signal lead unplugged or loose at its far end: the battery can seat perfectly and still not be recognised

Cross the fault first, while that information is still cheap. Two batteries and a minute of swapping tell you which half of the connection to replace.

⚠️ Common Replacement Indicators

Replace the battery interface board when inspection confirms one of these:

• Contact pins that are pitted, burnt or heat-darkened
• A pin bent, pushed back or out of line in its shroud
• A cracked, melted or deformed shroud
• A terminal pad that is damaged, lifted from the board or heat-marked
• A signal lead that is cut, crushed or pulled from the board
• Corrosion on the pins, pads or board after liquid has reached the bay
• Every battery faulting on this aircraft while the same batteries work on another

Inspect these first, because they produce similar symptoms:

• The battery's own connector, for damage or debris
• The battery bay and latch, for anything stopping full seating
• The power cable fastenings at the three terminal pads
• The signal lead's far-end connection
• Debris or residue on the contact pins

There is no published service interval for this board. It is replaced when its contacts, pads or lead are damaged, not on a calendar.

🛠️ Installation & Maintenance

Before installation

• Remove the flight battery and power the aircraft fully down; the board carries full flight current and must never be worked on with a battery in the bay
• Cross the fault with more than one battery so you know the board is the part to change
• Rinse and dry the battery bay area, then let it dry completely
• Photograph the old board in place from above, with each power cable at its terminal pad and the signal lead's routing in view
• Note which power cable goes to which pad, including the polarity mark
• Lay the new board beside the old one and compare outline, pin row, pad layout and lead

During installation

• Unplug the signal lead by its connector body, never by the wires
• Unfasten the power cables from the terminal pads one at a time and mark each as it comes off
• Unfasten the board at its mounting holes and lift it out square
• Inspect the bay for residue, corrosion or heat marks and clean it
• Seat the new board so its pin row lines up with the battery's path into the bay
• Fasten the mounting points evenly; no torque figure is published for these fixings, so snug them without stressing the board
• Refit each power cable to its marked pad, observing polarity, and tighten so the cable cannot move on the pad
• Plug the signal lead in fully and route it as it was, clear of sharp edges and the battery's path

After installation

• Check every terminal fastening and the signal lead before a battery goes near the bay
• Insert a known-good battery fully and latch it; it should seat without force
• Power up and confirm the battery is recognised and its readings look normal in the app
• Repeat with a second battery
• Make a short, light test hover, then check the battery bay for heat after landing
• Record the replacement in the maintenance log

Maintenance between jobs. Wipe battery cases before they go into the bay, look at the contact pins whenever a battery comes out, and never force or rock a pack into place. Heat at the bay after flight is the earliest warning the board gives; a battery connection that runs warmer than its neighbours on other aircraft is worth a look before it becomes a burnt pin.

🚜 Necessary For

This board is for operators and technicians who have traced a battery problem to the aircraft side:

• DJI Agras T20 operators whose every battery faults on one aircraft
• DJI Agras T16 operators (identified fitment)
• Commercial spray applicators running several packs per aircraft through long days
• Agras service centres and repair technicians clearing power faults
• Fleet managers with an aircraft whose battery bay runs hot
• Growers flying their own aircraft after a battery bay has taken in liquid

This is not the part you need if:

• One battery faults on every aircraft; the battery is the problem, not this board
• The battery is not fully seated or latched; clear the bay and seat it properly first
• Sand or chaff is sitting on the pins; clean and retest
• A power cable is loose at its pad; tighten it and retest
• You need to charge batteries; this board is part of the aircraft, not a charger
• You fly an Agras model other than the T20 or T16; this board is identified for those two only

💡 Why This Part Matters

Battery faults are blamed on batteries. That is natural: the pack is what the operator handles, the pack is what the app reports on, and packs are the item that wears out on a schedule everyone already expects.

But the connection has two halves, and only one of them leaves the aircraft. When the aircraft's half wears, burns or corrodes, every pack that goes into that bay inherits the fault. The operator sees a run of bad batteries. Good packs get set aside, sometimes replaced, and the fault is still there with the new one.

That is the case for this board, and for testing before buying it. A fault that follows the battery from aircraft to aircraft is the battery. A fault that stays with one aircraft whatever battery goes in is the aircraft side, and the battery interface board is the first part of the aircraft side the battery touches.

When it is the board, a new one gives every battery a clean, aligned set of contacts again. Fit it with each cable on its marked pad, plug in the signal lead, seat a known-good battery without force, and check the bay for heat after the first flight.

If you are unsure which board you have, send us a photograph of the one you removed and we will match it for you.

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 battery interface board? It is the aircraft-side board the flight battery connects to. The battery's connector mates with its contact pins, flight current passes through it to the aircraft's power cables, and a short lead carries the signal side of the connection.

Which aircraft does it fit? It is identified for the DJI Agras T20 and T16. Pick the variant for the aircraft you fly.

Is the T16 board the same as the T20 board? The board is identified for both aircraft. The variant records which one you fly, and we compare it with the board you removed if you send a photograph.

Is it a battery? No. It is part of the aircraft. It holds the contacts the battery plugs into; it stores no energy and charges nothing.

My batteries keep faulting. Is it the board or the packs? Cross the fault. If one battery faults on every aircraft, it is the battery. If every battery faults on one aircraft, the board is the first suspect.

The battery has to be pushed before it is recognised. Why? Look at the board's contact pins for wear, heat marks or a pin out of line, and at the bay for debris. Also check the signal lead is fully plugged in.

The battery bay gets hot after flight. Is that the board? Heat at the bay usually means a poor contact. Check that the battery is fully seated, the pins are clean and unmarked, and the power cables are tight at their pads. Burnt or darkened pins mean the board should be replaced.

What are the three square pads for? They are terminal pads where the aircraft's power cables fasten to the board. Mark each cable before removal and refit it to the same pad, observing the polarity mark.

What is the wire lead on the board? It is the multi-wire signal lead that carries the signal side of the battery connection into the aircraft. It comes attached to the board.

Does it come with cables or screws? It comes with its attached signal lead only. Power cables, terminal screws and mounting screws are not included.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph your old board and send it to us.

Can I fit it myself? Most technicians can. Remove the battery first, photograph and mark every cable, refit each to its pad with the correct polarity, plug in the signal lead, and test with two batteries before flying loaded.

Is it safe to work on with a battery fitted? No. The board carries full flight current. Remove the battery and power the aircraft down before touching it.

Is it new? Yes. The board is supplied brand new.

Is there a service interval? No. Replace it when its pins, pads or lead are damaged. Look at the pins whenever a battery comes out, and never force a pack into the bay.
