ENERpower Softpack battery 36V 17.25Ah for pedelecs, eBikes DIY with Samsung INR18650-35E

Important General Information

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

In the square version, 8 cells are used on the longest side (160 mm). We manufacture this type of battery in the formats 10S3P (construction 8×4), 10S4P (construction 8×5), 10S5P (construction 8×7) and 10S6P (construction 8×8).

In the rectangular version, 10 cells are used on the longest side (200 mm). We manufacture this type of battery in the formats 10S3P (construction 10×3), 10S4P (construction 10×4), 10S5P (construction 10×5) and 10S6P (construction 10×6).

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.
