DJI Agras T100S OEM Battery Air-Cooled Heat Sink Kit

The DJI Agras T100S OEM Battery Air-Cooled Heat Sink Kit is the forced-air cooling unit for the aircraft's battery, the assembly that moves air past the battery so heat is carried away rather than held. It is a grey housing, open at the top, with slotted vents along its side walls, a handle opening at each end of its upper rim, a cooling fan mounted inside, rows of connector terminals along one inner wall, a mounting plate across the top and a sloped base. It belongs to the aircraft's power system and it is identified for the DJI Agras T100S, T70S and T55. Operators usually reach it while searching for a T100S battery heat sink, a T70S battery cooling fan, a T55 battery air cooling kit, or the reason a T100S battery cooling fan has stopped spinning. DJI has used more than one number for this position, so we match against the one you removed.

🔧 Component Overview

The heat sink kit is the battery's cooling path. A large agricultural battery works hard through a day of flying and charging, and the heat it makes has to go somewhere. An air-cooled unit moves air past the battery so that heat is carried out through the vents instead of building up.

What it is, as described for this part:

• The housing — a grey, open-topped body with tall side walls
• The vents — rows of slots along the side walls that let air pass through
• The handle openings — a cut-out at each end of the upper rim
• The cooling fan — an axial fan mounted inside the housing
• The connector blocks — rows of multi-pin terminals along one inner wall
• The mounting plate — a plate across the top with fixing holes
• The base — a sloped foot the housing stands on

The fan, the connector blocks and the housing are fitted together as one kit, which is why it is replaced as an assembly when the housing is cracked or the fan has failed, rather than piece by piece.

Over a season the unit sees:

• Long hours of fan running through flying and charging cycles
• Dust, chaff and spray residue drawn into the vents and fan by the airflow
• Heat from the battery it is cooling
• Rinse water and cleaning between jobs
• Vibration and handling on every battery change
• Knocks during transport and loading

Units like this come out for a few real reasons: a fan that no longer spins or spins with a grinding noise, a fan blade broken by debris, a housing cracked by a knock, connector terminals bent or corroded, or vents and fan so packed with debris that cleaning no longer restores the airflow.

---

⚙️ Functional Purpose

The kit's engineering role is airflow. The fan pushes air through the housing and out through the vents, carrying heat away from the battery.

In the power system it:

• Drives air past the battery with its cooling fan
• Lets that air escape through the slotted side walls
• Carries connections along its inner wall through its connector blocks
• Mounts by its top plate and stands on its sloped base

What it does not do matters as much:

• It is not a battery and stores no energy
• It does not charge the battery; that is the charger
• It does not repair a battery cell that is failing and heating from inside
• It is not a charger cooling fan or a remote controller cooling fan
• It does not affect spraying, spreading or flight control

Cooling removes heat; it does not stop a failing pack making it. That line is the whole diagnosis.

🔍 Diagnosis — a hot battery is proven to be a cooling fault, not a battery fault, before the cooling unit is replaced

A battery that runs hot, a cooling warning in the app or a battery that takes longer before it is ready to charge can all point at the cooling unit. They can just as easily point at the battery itself, at blocked vents or at the conditions the aircraft is working in. A new cooling unit fixes only the first of those.

First, the fan. With the aircraft powered as it is when the fan should run, look and listen. A fan that does not turn, turns slowly or grinds is a cooling fault.

Then the airflow. Look into the vents and the fan for dust, chaff and residue. Packed vents choke a working fan, and cleaning them is the first repair.

Then the connections. Check the connector blocks for bent pins, corrosion or residue, and that whatever plugs into them seats fully.

Then the battery. If the fan runs, the vents are clear and the connections are clean, yet one battery still runs hot where others do not, the battery is the question, not the cooling unit. Swap batteries and see whether the heat follows the pack.

Signs the cooling unit itself is at fault:

• A fan that does not turn with power applied
• A fan that grinds, rattles or wobbles
• A broken fan blade
• A cracked or broken housing
• Bent or corroded connector terminals that cleaning does not restore
• Every battery runs hot in it, while the same batteries run normally elsewhere

Before condemning the cooling unit, rule out what imitates it:

• Blocked vents and fan — clean them first
• A single hot battery — if the heat follows one pack, the pack is the question
• Working conditions — hot days and back-to-back cycles make every battery warmer
• A loose or dirty connection — reseat and clean before replacing

Use the battery swap as your evidence. Heat that stays with the unit points at the unit; heat that follows a pack points at the pack.

Those checks take minutes on the ground and decide whether the cooling unit or the battery is the part to replace.

⚠️ Common Replacement Indicators

Replace the heat sink kit when inspection confirms one of these:

• A fan that will not spin with power applied
• A fan that grinds, rattles or has a broken blade
• A cracked or broken housing
• Connector terminals bent or corroded beyond cleaning
• Vents and fan so packed that cleaning no longer restores airflow

Inspect these first, because they produce similar symptoms:

• The vents and fan, for dust, chaff and residue
• The connector blocks, for seating and corrosion
• The battery, by swapping packs to see whether the heat follows one
• The working pattern, for back-to-back cycles in hot weather

There is no published service interval for the cooling unit. It is replaced when the fan fails or the housing breaks, not on a schedule.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove every battery
• Clean the vents and fan of the old unit and test again, so you know the unit is the part
• Photograph the old unit in place from above and the side, showing its connections and fixings
• Note which connector seats where before anything is unplugged
• Compare the new unit with the old one: housing, fan position, connector blocks and mounting plate

During installation

• Unplug connections by their bodies, releasing any locks first, never by pulling wires
• Remove the fixings at the mounting plate and lift the old unit out without straining any cable
• Clean the mounting area and check it for cracks or corrosion
• Set the new unit in the same orientation as your photograph shows
• Refit the fixings; no torque figure is published, so snug them without cracking the plate
• Remake each connection fully, matching your notes, and confirm nothing fouls the fan

After installation

• Power up and confirm the fan spins freely and quietly
• Feel for airflow at the vents
• Check no cable or debris sits in the fan's path
• Watch battery temperatures in the app over the next working day
• Record the replacement in the maintenance log

Maintenance between jobs. Blow dust and chaff out of the vents and fan, wipe residue from the housing and keep the connector blocks clean and dry. A fan that starts to sound different is worth a look before it stops.

🚜 Necessary For

This kit is for operators and technicians whose battery cooling has failed:

• DJI Agras T100S operators with a cooling fan that will not spin
• DJI Agras T70S operators (identified fitment)
• DJI Agras T55 operators (identified fitment)
• Commercial applicators running back-to-back battery cycles through long days
• Agras service centres replacing a cracked housing or a fan broken by debris
• Growers flying their own fields who keep a spare cooling unit for the busy season

This is not the part you need if:

• One battery runs hot and the others do not — the heat follows the pack, so the pack is the question
• The vents and fan are only packed with debris — clean them
• A connection is loose or dirty — clean and reseat it
• You need a battery — this is a cooling unit; it stores no energy
• You need a charger or remote controller cooling fan — those are separate parts
• You fly a T100, T70P, T60 or T50 — this kit is identified only for the T100S, T70S and T55

💡 Why This Part Matters

A battery that cannot shed its heat works harder than it needs to. The cooling unit is what moves that heat out, and when its fan stops or its housing breaks, the battery loses its airflow.

The case for this part is a misdiagnosis one. A hot battery looks like a cooling problem, and sometimes it is. Sometimes it is a pack that is failing and making heat from inside, and no amount of air will change that. Sometimes it is only vents packed with chaff. Each of those has a different repair.

The checks sort them quickly. Look and listen at the fan. Clean the vents. Reseat the connections. Then swap batteries: heat that stays with the unit is the unit, and heat that follows a pack is the pack.

A failed fan or a broken housing is a cooling unit to replace, and a new one restores the airflow. A hot battery in a working cooling unit is a battery to look at instead.
