Our little battery just got a big upgrade!! Welcome the Fenix ARB-L16-700U USB rechargeable li-ion battery! The ARB-L16-700U battery can be charged by its own USB port and by the charger as well. A protective circuit is built into the anode and covered with a riveted steel hat. The battery is fully covered with the steel shell, thus the potential risk of short circuiting caused by collision or impact is hugely eliminated!
