ENERpower Softpack battery 48V (13S7P) 21Ah for Pedelecs, eBikes DIY with Samsung 30Q battery cells.
The 48V (46.8V-48.1V) batteries in softpack in format 13S, which we assembled, have 2 formats – square and rectangular. The batteries are assembled with cells-holders made of plastic.
Charging is enabled with a DC round plug (5.5 mm / 2.5 mm); discharging is enabled with a discharge cable with XT90 connector. A safety fuse of 30A in a water resistant holder limits the current rate.
In this rectangular version, 13 cells are used as the longest side (260 mm). We assemble this type of battery in formats 13S7P (built 13×7), 13S8P (13×8) and 13S9P (13×9).
In this softpack we use high quality NR18650-30Q from Samsung SDI, which function well also in low temperatures and maintain the voltage also around the freeze point.
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.
