The ARB-L14-1600U can be used as AA batteries and can be charged by its own USB port. 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.
