Important general information

The 36V batteries in softpack, which we assemble, 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 the square version, 8 cells are used as the longest side (160 mm). We assemble this type of battery in formats 10S3P (8×4), 10S4P (8×5), 10S5P (8×7) and 10S6P (8×8).

In the rectangular version, 10 cells are used as the longest side (200 mm). We assemble this type of battery in formats 10S3P (10×3), 10S4P (10×4), 10S5P (10×5), 10S6P (10×6) 10S8P (10×8).

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.
