ENERpower softpack battery 24V (25.2V-25.9V) 20.4Ah for pedelecs, eBikes DIY with Samsung SDI INR18650-35E. Smart BMS 40A for motors up to 1000 Watt

Important General Information

This 24V battery in softpack is in 7S format (25.2V-25.9V) and is manufactured with the battery cells of Samsung SDI, or Panasonic. The batteries are manufactured in cell holders made of plastic and equipped with a BMS 40A brand ENERpower. The charging is equipped with a spiral cable (20-100 cm extendable) with an XLR-3-pin connecting piece. Charging is done with a flexible coiled cable with an XLR 3-PINS connector. Discharging is made possible via a discharge cable with XT90 connector (male). A counterpart XT90 is also included.

A fuse (fuse) of 60A in a waterproof holder limits the current drain and provides an additional safety measure.

This battery is also suitable for engines with 1000 watts of power .

We manufacture the Softpack batteries with FR4 insulation, flame retardant composites made of epoxy resin and glass fabrics. FR-4 is used, among other things, as an electrically non-conductive carrier material for electrical circuit boards.

In this battery we have also integrated a charging indicator. In 5 levels (empty / 25% / 50% / 75% / full) you can easily read the battery’s charge status.
