General Info

This series of 2S batteries, which we manufacture in Berlin as replacement batteries for various brand lamps, is offered in various versions. We manufacture the batteries in the formats 2S1P, 2S2P, 2S3P and 2S4P. The S stands for the serial circuit (voltage). The P stands for the parallel circuit (increase of capacity). The Li-ion batteries from Enerpower 2S (7.2V-7.4V) are manufactured with high-quality battery cells in the 18650 and 20700 formats. Our protective circuit (about 7A-8A) can light lamps up to about 50 watts.

The charging indicator shows the state of charge in 5 stages as follows: Empty / 25% / 50% / 75% / Full
