e-bike batteries

bidon housing

Batteries for electric bikes, e-bikes or mopeds. Real distance on one charge – up to 60 miles.

We make 36V or 48V batteries with capacity from 11.6 to 17.5 Ah. There is a possability to prepare a series of batteries with a different capacity or voltage. Batteries are made from brand new cells, selected by our machines.

The cells are welded automatically, which guarantees strong, regular welds with a thick nickel plate, which perfectly dissipates heat.

The cell package – secured by the BMS (battery management system) – was placed in the Hi-Long housing. The housing is additionally sealed in the last stage of production.

The battery connects to the rail through gold-plated round pins – this additionally stabilizes the battery and allows for efficient energy flow.

The rail is screwed to the bicycle frame, the battery is then inserted into the rail and secured with a mechanical lock against unauthorized removal.

Charging the battery is just as simple as connecting it to the charger, which is then plugged into a standard electrical outlet.

The battery fits most electric bikes that are available on the market.

Standard bicycle batteries can be bought directly from the Battery Guru on-line store.
