Description
The FENIX ARB-L21-4000P is a high-capacity 21700 Li-ion rechargeable battery that is designed for longer runtimes at higher levels. It features a protection circuit in the anode to help prevent short circuits, overcharge/discharge and over heating. It also has pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion.
ARB-L21-4000P is a high-capacity 21700 Li-ion rechargeable battery
built for longer runtimes at higher levels. These battery allows a high
output flashlight like the LR35R to have its turbo setting of 10000
lumens to maintain it's output by maintaining higher voltage for longer
periods of a batteries charge. Additional features include a protection
circuit in the anode to help prevent short circuits, over
charge/discharge and over heating. Pressure relief vents which expel
waste gas in the rare case of an internal short circuit preventing an
explosion.
