TB100C Tethered Battery The TB100C Tethered Battery is purpose-built to power DJI Matrice 400 drones for uninterrupted, long-duration flights by supplying energy via a dedicated tethered cable. With a robust 20,254mAh (977Wh) capacity and a standard voltage of 48.23V, it ensures continuous operation for lighting, communication, surveillance, or inspection missions where battery swaps are not feasible. Weighing approximately 4.72kg, the TB100C features intelligent power management with real-time voltage, temperature, and current monitoring for enhanced safety and reliability. Unlike portable batteries, the TB100C enables drones to remain airborne for extended periods, crucial for tasks such as live broadcasting, infrastructure monitoring, public safety, or research. The battery features self-heating for reliable cold-weather operation down to –20°C and supports hot-swapping (up to 45 seconds of backup on the drone) to maximize deployment flexibility. Reserved ports allow integration with third-party lighting, communication devices, or automated drone docks, supporting future expansion and custom workflows.
