EVE INR21700-50PL is a 21700 format Li-ion cell with a capacity of 5000mAh. The cell features a Flat Top without protection circuitry and weighs approximately 72g.
The cell can handle a very high discharge current of up to 125A (25C). It is thus suitable for creating power packs for FPV drones. A disadvantage is the shorter lifespan of the battery—100-200 cycles. When stored long-term, the battery should be checked after a few months and recharged to storage voltage if necessary.
