Important General Information

The 36V batteries in softpack, which we manufacture in Berlin, have 2 versions square and rectangular. The batteries are manufactured in plastic cell brackets. Charging is done with a high-quality spiral cable (20 cm – 100 cm) with an XLR-3 PINS, discharging via a discharge cable with XT90 connector (male). A fuse of 30A in a water-resistant holder limits the current drain.

In the square version, 7 cells are used on the longest side (around 165 mm). We manufacture this type of battery in the format 10S4P (construction 7×6)

In the rectangular version, 10 cells are used on the longest side (200 mm). We assemble this type of battery in the formats 10S2P (construction 10×2), 10S3P (10×3), 10S4P (10×4), 10S5P (10×5) and 10S6P (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.

In this battery we have an LED charge status display (empty/25%/50%/75%/full). This is located on the upper side of the battery

Compatible with 36V motors
