Important General Information

The 48V (46.8V-48.1V) softpack batteries in 13S format that we manufacture have 2 versions – square and rectangular. The batteries are manufactured in plastic cell brackets. Charging is possible with a spiral cable (20-100 cm) with an XML-3-pin, 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 of the battery we designed it so that the length and width of the battery are kept as square as possible, such as (e.g.): 13S3P (built 6 x 5), 13S4P (built 8 x 7), 13S5P (built 9 x 8), 13S6P (built 9 x 9)

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 integrated a charge status indicator. In 5 levels (empty / 25% / 50% / 75% / full) you can determine the state of charge of the battery.
