ENERpower Softpack 24V 7S3P 10.35Ah with BMS Pedelec Battery (7×3) DIY 3XLR

158.00 Inc. 19% Vat.

Rectangular ENERpower softpack battery 24V (25.2V-25.9V) 10.35Ah for Pedelecs and eBikes DIY.
Powered by Samsung SDI INR18650-35E.

Important general information

The 24V batteries (25.2V – 25.9V) in softpack, which we assembled, have 2 formats – square and rectangular. The batteries are assembled with cells-holders made of plastic.
Charging is enabled with a 3XLR plug; discharging is enabled with a discharge cable with XT90 connector. A safety fuse of 30A in a water resistant holder limits the current rate.

The BMS (Battery Management System) is always mounted on the longest side of the battery. At this point the battery is approx. 10 – 15 mm thicker.

The softpack batteries are manufactured with FR4 isolation, inflammable and flame-retardant composites consisting of epoxy resin and fiberglass cloth. FR-4 is used, inter alia, as an electrically non-conductive carrier material for electrical printed circuit boards.
