ENERpower Softpack Battery 36V 10.35Ah for Pedelecs, E-Bikes DIY with Samsung INR18650-35E rectangular.

Important General Information

The 36V batteries in the Softpack, which we manufacture, have 2 versions: square and rectangular. The batteries are manufactured in plastic cell brackets. Charging is made possible with a DC round plug (5.5 mm/2.5 mm), discharging is carried out via an discharge cable with XT90 connector (male). A fuse of 30A in a water-resistant holder limits the current drain.

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

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.
