DJI Agras T20 OEM Intelligent Flight Battery

The DJI Agras T20 OEM Intelligent Flight Battery is the removable flight battery that powers the DJI Agras T20 spray aircraft. It slides into the aircraft's battery bay, where its connector meets the aircraft's battery interface board, and from there it feeds every motor, the pump, the flight controller and the radar on every sortie. It belongs to the power system, it is identified for the DJI Agras T20, and it is supplied brand new as a single grey rectangular pack with black corner bumpers, a carry handle on top, and a power button with charge-level LEDs, as shown in the product images. Operators usually look for it as a T20 battery, an Agras T20 flight battery, a DJI T20 smart battery or a T20 intelligent battery when they are adding a pack to their rotation, or when a pack has been damaged, has swollen, or faults on every aircraft it goes into. 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 Intelligent Flight Battery, as shown in the product images

One battery. A single complete flight battery pack, ready to be charged and fitted. It is not a set of cells, not a battery shell, and not a charger.

What is part of the battery: the grey case with its black corner bumpers, the carry handle on top, the power button and charge-level LEDs, and the pack's own connector that meets the aircraft. These come with the battery because they are the battery.

Not included: the battery charger, charger cables or charging hub, a generator or power supply, a storage or transport case, the aircraft's battery interface board, and the battery bay latch. 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 more than one pack, a floor, a box or anything not named above, it is not part of the order. The order is one battery.

🔧 Component Overview

Everything the Agras T20 does in the air runs on one pack at a time. The intelligent flight battery is that pack: it carries the stored energy for a sortie, it delivers the heavy current a loaded spray aircraft draws on take-off, and it reports its own state so the operator and the aircraft know what is left in it.

As shown in the product images, the battery is a grey rectangular pack with four working features:

• The case — a grey rectangular housing that holds and protects the cells and the battery's own electronics
• The corner bumpers — black protective corners that take the knocks of handling, stacking and loading
• The carry handle — on top of the pack, for lifting it in and out of the bay and between the charger and the aircraft
• The power button and charge-level LEDs — on the pack, for switching it on and reading its charge level at a glance

The word intelligent describes the battery's own management electronics. The pack is not a plain block of cells: it monitors itself, shows its charge level on its LEDs, and reports its state to the aircraft through its connector.

Where it sits and what it touches:

• Position: the aircraft's battery bay, loaded from outside and latched in place
• On the aircraft side: the battery interface board, through the pack's connector
• Between sorties: the charger, which it visits after almost every flight
• System: power, at the source of everything the aircraft does

A flight battery on a spray aircraft leads a harder life than almost any other part. Over a season it sees:

• A full charge and a deep discharge on most working days, often several times a day
• Heavy current on every take-off with a loaded tank
• Heat from flight followed straight away by heat from charging, when a rotation runs tight
• Knocks and drops in the field, on tailgates and in the back of a truck
• Dust, chaff and spray residue on the case and the connector
• Long idle periods between seasons, which have their own effect on a lithium pack

Packs are retired for a handful of reasons: a swollen, cracked or punctured case, a damaged connector, a pack that faults on every aircraft it is fitted to, or a pack that no longer holds a sortie's worth of energy. Operators also add packs simply to keep the aircraft flying while the others charge.

⚙️ Functional Purpose

The battery's engineering role is energy. It stores the energy for a sortie, delivers it at the current the aircraft demands, and manages itself while it does so.

In the power system it:

• Stores the energy the aircraft flies and sprays on
• Delivers flight current through its connector to the aircraft's battery interface board
• Monitors its own condition through its built-in management electronics
• Reports its state to the aircraft through the signal side of its connector
• Shows its charge level on its LEDs when the power button is pressed
• Accepts charge from the charger between sorties

Because every system on the aircraft draws from it, the pack's condition shows up as the aircraft's condition. A pack that cannot hold its voltage under load does not only shorten a sortie. It shows up as a warning in the app, an early return, or a pack the aircraft will not accept.

What the battery does not do matters as much:

• It does not form the aircraft's half of the battery connection; the battery interface board in the bay does
• It does not latch itself into the aircraft; the battery bay and its latch do
• It does not charge itself; the charger does
• It does not distribute power to the motors; the aircraft's power wiring does
• It does not decide how far the aircraft flies on its own; payload, conditions and flight settings all draw on it

🔍 Diagnosis — does the fault follow the pack, or stay with the aircraft

When a T20 shows a battery warning, the pack is the first thing blamed and the first thing replaced. Packs are the item the operator handles, they are the item the app reports on, and they are the item everyone expects to wear out.

Often that is right. But the battery connection has two halves, and only one of them is the pack. The other half is the battery interface board in the aircraft's battery bay. A worn, burnt or misaligned contact on that board gives the same warnings as a failing pack, and it gives them with every pack you fit.

Cross the fault before you buy a pack. Most operators run several packs, and many run more than one aircraft. That makes the test free:

• One pack faults on every aircraft: the pack is the problem, and this battery is the part you need
• Every pack faults on one aircraft: the aircraft side of the connection is the suspect; the part you need is the T20 battery interface board, not a battery
• One pack 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 pack:

• A swollen, bulging or misshapen case
• A cracked, dented or punctured case, or a broken corner bumper over a damaged case
• A damaged, burnt or bent connector on the pack
• The same warning or the same short sortie with this pack on more than one aircraft
• A pack that runs noticeably shorter than the others in the same rotation under the same load
• A pack that will not wake when the power button is pressed, while the others do

Clear these first, because they imitate a bad pack:

• A pack not fully seated or latched: a partly inserted pack makes poor contact with a healthy aircraft
• Debris on the connector or in the bay: sand, chaff or residue holds the pack off its contacts; clean and retest
• A pack that is simply flat: check the charge-level LEDs and charge it before condemning it
• A pack still hot from the last sortie: let it cool before charging or judging it
• Worn or burnt pins on the aircraft's battery interface board: inspect the bay side of the connection

Two packs and two minutes of swapping tell you which half of the connection to replace. That is the cheapest test in the whole power system.

⚠️ Common Replacement Indicators

Replace or retire the intelligent flight battery when inspection confirms one of these:

• A swollen or bulging case, whatever the LEDs and the app report
• A cracked, punctured or crushed case
• Any sign of leakage, scorching or a burnt smell from the pack
• A damaged, bent or burnt connector on the pack
• The same fault from this pack on more than one aircraft
• A pack that no longer completes the sorties the rest of the rotation completes under the same load
• A pack that has been through a hard impact or a crash, even if it looks intact

Inspect these first, because they produce similar symptoms:

• The aircraft's battery interface board, for pitted, burnt or misaligned pins
• The battery bay and latch, for anything stopping full seating
• The pack's connector, for debris or residue that can be cleaned
• The pack's charge level, in case it is simply flat
• The charger and its connection, if the pack will not take charge

There is no service interval for the pack as a whole. Retire it on physical damage at once, and on performance when it falls behind the rest of the rotation.

⚡ High-Energy Battery Safety Notice

The DJI Agras T20 Intelligent Flight Battery is a high-energy lithium battery. It stores enough energy to lift a loaded spray aircraft, and that energy is released as heat and fire if the pack is damaged, shorted or abused. Treat every pack accordingly.

On arrival

• Inspect the pack before its first charge: case, corners, handle, button panel and connector
• Do not charge or fly a pack that arrives swollen, cracked, punctured, dented or leaking; set it aside outdoors on a non-flammable surface and contact us
• Check the charge level with the power button before charging

Charging

• Charge only with the DJI charging equipment identified for the Agras T20
• Let a pack cool after a sortie before it goes on the charger
• Charge on a non-flammable surface, away from fuel, chemical stock and dry vegetation
• Stay with packs while they charge, and stop charging any pack that becomes unusually hot, swells or smells of burning

Handling and flight

• Carry the pack by its handle and do not drop it; a hard impact can damage cells inside an intact-looking case
• Keep the connector clean and dry, and never let metal objects bridge its contacts
• Seat the pack fully and latch it every time; a partly seated pack heats the contacts
• Do not immerse the pack or wash it under running water; wipe residue from the case with a damp cloth
• After any crash or hard landing, inspect the pack before it is charged again

Storage and transport

• Store packs in a cool, dry place out of direct sun and away from heat sources
• Do not leave packs in a closed vehicle in hot weather
• Follow the charge-level guidance in DJI's documentation for the T20 when packs are stored for long periods between seasons
• Transport packs secured so they cannot slide, fall or be crushed, and follow the carrier's rules for large lithium batteries

Retirement and disposal

• Retire a swollen, punctured, leaking or crash-damaged pack at once, whatever its LEDs or the app report
• Do not open, puncture or attempt to repair a pack
• Dispose of retired packs through a lithium battery recycling point under your local rules; never in household waste

A swollen case is the one battery fault that never needs a second opinion. If a pack has changed shape, it is finished.

🛠️ Installation & Maintenance

Before installation

• Cross the fault with more than one pack and more than one aircraft if you have them, so you know the pack is the part to change
• Inspect the new pack: case, corner bumpers, handle, button panel and connector
• Press the power button and read the charge level on the LEDs
• Charge the new pack fully with the DJI charging equipment identified for the T20 before its first sortie
• Inspect the aircraft's battery bay and the battery interface board pins for debris, heat marks or damage
• Power the aircraft fully down before loading or removing any pack

During installation

• Lift the pack by its carry handle; do not carry it by the connector end
• Line the pack up with the battery bay and slide it in straight
• Push it home without rocking or forcing it; a pack that will not seat has something in its way
• Latch it fully and check it cannot move in the bay
• Power on and confirm the aircraft recognises the pack and its readings look normal in the app

After installation

• Make a short, light test hover before flying with a loaded tank
• After landing, check the pack and the battery bay for unusual heat
• Let the pack cool before it goes back on the charger
• Mark the pack so you can track it in the rotation
• Record it in the maintenance log alongside the others

Maintenance between jobs. Wipe each case and connector before it goes into the bay, keep packs in rotation so none sits idle for months while others do all the work, and compare sortie lengths across packs on the same job. The pack that consistently falls behind the others is the one to watch, and the pack that swells is the one to retire.

---

🚜 Necessary For

This battery is for T20 operators who need another pack in the rotation, or who have traced a fault to a pack:

• DJI Agras T20 operators adding packs so the aircraft keeps flying while others charge
• T20 operators retiring a swollen, damaged or crash-affected pack
• Commercial spray applicators running long days on a T20
• Agras service centres and repair technicians returning a T20 to service
• Fleet managers balancing pack count against aircraft count
• Growers flying their own T20 who need a dependable spare

This is not the part you need if:

• Every pack faults on one aircraft while the same packs work on another; that points at the aircraft side, and the part you need is the DJI Agras T20 OEM Battery Interface Board
• A pack is simply flat; charge it and retest
• A pack will not seat because of debris in the bay or on the connector; clean it and retest
• The charger head or its cover is damaged; that is a charger part, not a battery
• You fly a T16 or another Agras model; this pack is identified for the T20 only, and battery packs for other Agras aircraft are different packs

💡 Why This Part Matters

A flight battery is the most expensive part on a T20 that an operator replaces regularly, and it is also the part most often replaced when something else has failed.

The reason is simple. The pack is what the operator handles, and the pack is what the app reports on. So when the aircraft gives a battery warning, a pack gets set aside. If the warning comes back with the next pack, another gets set aside. Good packs end up on the shelf while the real fault sits on the aircraft's battery interface board.

That is why the first step is a swap, not a purchase. A fault that follows a pack from aircraft to aircraft is the pack, and this battery fixes it. A fault that stays with one aircraft whatever pack goes in is the aircraft, and a new battery will inherit it.

There are two cases where no test is needed. A pack whose case has swollen, cracked or been punctured is finished, whatever its LEDs say. And an operator whose aircraft waits on the charger between sorties needs another pack in the rotation, not a repair.

When it is the pack, a new one restores the rotation: charge it fully, seat and latch it without force, fly a light test hover, and add it to the log.

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

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 intelligent flight battery? It is the removable flight battery that powers the Agras T20. It slides into the battery bay, feeds every system on the aircraft, and reports its own state through built-in battery management.

Which aircraft does it fit? It is identified for the DJI Agras T20. Send us a photograph of the pack you fly and we will match it.

Will it fit my T16? It is identified for the T20 only. Battery packs for the T16 and other Agras aircraft are different packs.

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

What capacity is it? Capacity, voltage and cycle figures are not published for this part. We match it against the pack you fly.

Does it come with a charger? No. The order is one battery. Chargers, charger cables, power supplies and storage cases are separate.

My batteries keep faulting. Do I need a new battery? Cross the fault first. If one pack faults on every aircraft, it is the pack. If every pack faults on one aircraft, the aircraft's battery interface board is the first suspect, and a new battery will not fix it.

My battery case has swollen but still reads fine. Can I keep flying it? No. A swollen case retires the pack whatever its LEDs or the app report. Stop using it, keep it outdoors on a non-flammable surface, and dispose of it through a lithium battery recycling point.

What do the lights on the battery show? The LEDs beside the power button show the pack's charge level when the button is pressed.

Why does the battery have to be pushed before the aircraft sees it? Check the bay and the pack's connector for debris, make sure the pack is fully latched, and look at the battery interface board's pins for wear or heat marks.

Can I charge it straight after a flight? Let the pack cool first. Charge on a non-flammable surface with the DJI charging equipment identified for the T20, and stay with it while it charges.

How should I store it between seasons? Store it cool and dry, out of sun and away from heat, and follow the charge-level guidance in DJI's documentation for the T20 for long-term storage.

Can I wash spray residue off the battery? Do not immerse it or put it under running water. Wipe the case with a damp cloth and keep the connector clean and dry.

How many batteries do I need? Enough that the aircraft never waits on the charger between sorties. If your T20 sits on the ground while packs charge, another pack in the rotation is the fix.

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 pack and send it to us.

Is it the battery or the charger head cover I need? If the pack itself is damaged or faults on every aircraft, it is the battery. If the charger's head housing is cracked or broken, that is the charger head cover, a charger part.
