2S Batteries (7.2V – 7.4V)
For Bicycle Lights and more

These ENERpower generic Li-ion batteries for branded flashlights such as Lupine©, My Tiny Sun© and Sigma© are equipped with a Molex-1625 plug and assembled in various variations.

The batteries have a nominal voltage of 7.2V – 7.4V (2S) and are assembled with branded battery cells (Samsung SDI, Panasonic [Sanyo], LG Chem).

In each format (2S1P, 2S2P, 2S3P and 2S4P), we offer two variations with different capacities.

We also assemble the batteries with different settings, as follows:

  1. ENERpower Basic: with PVC shrink
  2. ENERpower Plus: with rubber cover & PVC shrink
  3. ENERpower Pro: with LED-Display

The different models are named after a district of Berlin, our beloved home city.
