Fenix Flashlight

The ARB-L21-4000P 21700 Rechargeable Lithium-Ion Battery from Fenix Flashlight is designed for flashlights and other high-drain devices requiring increased battery capacities and extended runtimes. The cell maintains its output for long periods of time, and this high-capacity 21700 battery allows a high-output flashlight to function when using its turbo setting. Safety features include a built-in protection circuit to help prevent overcharging, discharging, overheating, and short circuits. Additionally, pressure relief vents expel waste gas in the rare case of an internal short circuit. The battery is engineered for 500 charging cycles and is compatible with the ARE-A2, ARE-A4, ARE-D1, and ARE-D2 battery chargers.
