DJI TB100C Tethered Battery

DJI TB100C Tethered Battery

Overview
The DJI Matrice 400 TB100C Tethered Flight Battery pairs the high-capacity 20,254 mAh, 977 Wh power of the TB100 with ports dedicated to third-party tethered systems.
When connected to approved cabled ground stations, the TB100C supplies continuous power for persistent aerial lighting, comms relays, or dock-based operations—unlocking near-unlimited airtime for Matrice 400 fleets.
Reserved I/O interfaces also support integrators building automated recharge docks and other enterprise solutions.

Tips
Use only with certified tether kits or DJI-approved docks.
Do not splice or modify the tether cable.
