Important General Information

The 52V (14S) 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 40A in a water-resistant holder limits the current drain.

In the square version, 10 cells are used on the longest side (220 mm). We manufacture this type of battery in the formats 14S3P (construction 10×5), 14S4P (construction 10×6), 14S5P (construction 10×7) and 14S6P (construction 10×9) etc.

In the rectangular version, 14 cells are used on the longest side (288 mm). We assemble this type of battery in the formats 14S2P (construction 14×2), 14S3P (14×3), 14S4P (14×4), 14S5P (14×5) and 14S6P (14×6) etc.

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.
