Ett litiumbatterifodral är en tom låda eller skal som innehåller litiumbatterier eller ett litiumbatteripack inuti. Vanligtvis, it has electrical connectors to support the lithium batteries’ charge/discharge. Some lithium battery cases have USB ports or LED capacity displays for special functions.

The core function of the lithium battery case is to protect the lithium battery from damage. Lithium battery cases can keep the whole lithium battery pack away from moisture, damm, and strike, which can help the lithium battery pack inside work in stability, ensuring a longer lithium battery pack lifespan.

The lithium battery cases can be made from different materials, like plastic, aluminum， and stainless steel. Different materials have advantages and disadvantages for lithium battery case applications.

Plastmaterial kan urskilja olika former och är lätta att gjuta, det är fördelen med plast litium batterifodral, speciellt för de flesta Ebike litiumbatterifodral.

Låg densitet, korrosionsbeständighet, slagtålighet, stötmotstånd, lätt gjutning, lågt pris.

Good collision energy absorption effect, strong anti-rust ability. Alloy aluminum has a lighter weight compared to steel material.

Stainless steel lithium battery cases are with excellent chemical resistance and corrosion protection, are high-strength shock-resistant and are suitable for use in electric vehicles.

But the steel lithium battery case is not as safe as the aluminum battery case, it will explode if a short circuit happens.
