Keeppower Li-ion Akku 14500 mit 1100mAh 3,7V, 50,3x14,2mm, mit USB Lademöglichkeit

Li-ion Battery 14500 3.6V - 3.7V 1100mAh in AA (Mignon) size. The Keeppower 14500 Li-ion battery offers a capacity of 1100mAh and a voltage of 3.7V - 3.6V with USB charging capability and PCB P1411U. Thanks to state-of-the-art chemical components, the P1411U achieves the length of an AA battery despite the BMS/PCB electronics and USB charging port.

It features an integrated Micro-USB charging port and charging electronics with a charging status indicator. A built-in PTC prevents high current surges. The innovative anode design provides high temperature resistance, and a pressure relief valve is activated in case of rapid temperature increase. The IC protection/PCB offers protection against short circuits, overcharging, and deep discharge.
