ENERpower softpack battery 36V (set-up 10S4P) 20Ah for eBikes, with M50 battery cells from LG Chem in Roswheel Attack bag

Important General Information

This 36V e-bike battery in softpack is manufactured for insertion in Roswheel carrier bag (Attack). With this bike-frame bag, you can attach the battery to the frame of the eBike and ideally connect it to a mid-sized engine. The frame bag is waterproof and with the separation between charging and discharging cables you don’t have to overplug constantly.

The battery cells are assembled in a plastic holder and equipped with a ENERpower branded BMS 20A-22A. The charging is done with a spiral cable (20-100 cm extendable) with an XLR-3-pin connector. Discharging is done via a discharge cable with XT90 connector (male). A counterpart XT90 is also included.

A safety fuse of 30A in a waterproof mount limits the power consumption and provides an additional safety measure.

This battery is also suitable for engines with up to 750 watts of power.

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.

The high-quality Roswheel Attack bike-frame bag makes it easy to place the battery under the top frame (as seen in the photos). This carrying bag is water-spray-tight and can carry up to about 5 kg.
