Rincell's RC50T pushes a 21700 cell toward high-current drone loads
Rincell is preparing to show its RC50T tabless 21700 lithium-ion cell at DroneX in London on 29 and 30 September. The company claims 100 A continuous discharge, 150 A pulse discharge, energy density above 265 Wh/kg and 3 to 4 milliohms internal resistance. These are manufacturer specifications, not independent test results.

High-current cylindrical cells are increasingly relevant to drone packs that need strong takeoff and climb performance without moving to a pouch-cell format.
Do not translate a cell-level current rating directly into a pack limit. Validate voltage sag, temperature, interconnect losses, BMS or protection behavior, cooling and cycle life at the real aircraft duty cycle.
