Fenix 21700 Rechargeable Battery 5000U

This 21700 battery from Fenix is designed to handle the additional mAh's for high lumen flashlights giving them longer run times. What makes this 21700 battery even better is the USB Type-C charging port that is embedded in the cell. You don't have to use a separate charger to charge the battery; it can all be done with a wall adapter and USB Type-C charging cord. It is likely that you already have these in your home since many cellphones use this same type of charging port.
