3.6V – 3.7V Batteries: small but powerful

Under the ENERpower brand we assemble a range of li-ion batteries with protection circuits. Our PCBs (Protection Circuit Boards) are UL certified, as well as the PVC shrink film that we use.

ENERpower's batteries are characterized by their quality and safety. Using our own assembly technology, we weld the button top (the positive terminal) directly to the cell, thereby reducing internal resistance.
