7.2V – 7.4V Batteries
For Bicycle Lights, RC Helicopters and more

Under the ENERpower brand we assemble a variety of Li-ion batteries that are connected in a series. Under this category we present several 2S (7.2V - 7.4V) batteries.

The batteries are equipped with a DC plug. While they are compatible with many devices, they are especially well suited for bicycle lights as well as for remote-controlled drone-helicopters. A PCB (Protection Circuit Board) with 3 MOSFETs allows a continuous current of up to 9A and a dual electrical output cable is fixed to the battery. The different batteries are each named after a district of Berlin, our beloved city.
