Rincell's RC50T targets high-current drone packs in a standard 21700 format

Rincell announced the RC50T ahead of DroneX in London. The company rates the 5.2 Ah silicon-graphite 21700 cell for 100 A continuous and 150 A pulse discharge, energy density above 265 Wh/kg and internal resistance of 3-4 milliohms.

Drone packs often force a choice between cells optimized for energy and cells that tolerate aggressive takeoff, climb and payload currents. A high-discharge cylindrical cell could give pack designers another option between conventional energy cells and high-C-rate pouch packs.

These are manufacturer figures. Pack-level thermal behavior, busbars, cell matching, BMS limits and cycle life still need validation in the actual aircraft duty cycle.
