DJI T100 Dual-Battery Spraying System preflight and cable safety checklist

DJI T100 Dual-Battery Spraying System Preflight & Safety Checklist

September 17, 2026

The Product Information sheet does not provide a separate formal preflight chapter, but its warnings can be converted into a practical inspection sequence without adding unsupported requirements. This checklist focuses only on the conditions DJI explicitly identifies.

Quick Answer: Before operating the dual-battery spraying system, confirm the aircraft is a T100 with supported firmware, use the payload recommended by DJI Agras, verify cable connections are correct and secure, inspect the shell/seals and waterproof covers, and keep hands clear of sharp or moving mechanical parts.

1. Confirm T100 aircraft compatibility

This product-information revision supports the T100 aircraft only. Do not apply this accessory workflow to other Agras models.

2. Confirm firmware support

The aircraft firmware must support the dual-battery spraying system. A compatibility problem should be ruled out before treating a missing system function as a hardware fault.

3. Use the DJI Agras payload recommendation

The source does not state one fixed maximum load for every condition. The app recommends payload based on aircraft status and surroundings. Do not overload the spray tank beyond the app recommendation.

4. Inspect cable connections

T100 dual battery spraying aircraft side cable connector preflight inspection — Inspect the same aircraft-side connector shown in steps 4-5 of the installation figure.

Make sure the connection is correct and secure and that the cable has not been damaged during installation or handling.

5. Inspect waterproof covers and sealing areas

T100 dual battery spraying IPX6 seal and waterproof cover inspection — DJI identifies collision deformation, cracked seals and unsecured waterproof covers as conditions that can reduce protection.

If the aircraft or spraying assembly has experienced an impact, inspect sealing areas before assuming the original IPX6 performance remains intact.

6. Keep clear of sharp or moving mechanical parts

DJI explicitly warns about injury from sharp or moving mechanical parts. Complete inspection and adjustments before beginning an operation.

Useful T100 spraying-system service paths

For broader spray-system maintenance, the T100 Spray System Critical Spares Pack and T100 100 Mesh Filters (5 Pcs) are active catalog items. These are not identified as LS100-DB-specific parts in the source, so they are presented only as broader T100 spraying-system service options.
