Rincell brings a 100 A continuous-discharge 21700 cell to DroneX

Rincell is using DroneX in London for its European debut of the RC50T, a tabless 21700 lithium-ion cell that the company rates at 100 A continuous and 150 A pulse discharge, above 265 Wh/kg, with 5.2 Ah nominal capacity. Rincell says the cell is already shipping to drone manufacturers.

High-discharge cylindrical cells can reduce the usual penalty between endurance-oriented packs and the peak current required for climb, payload lift and aggressive maneuvering.

Pack builders should validate thermal behavior, voltage sag, cycle life and current sharing at pack level rather than extrapolating directly from cell ratings. Rincell projects more than 500 cycles for the RC50T, lower than its endurance-oriented RC50.
