Lithium batteries


Lithium batteries as complete lithium cell batteries are modern energy storage devices for almost unlimited use. Li-Ion or LiFePO4 lithium batteries excel in charging speed, high capacity and up to 10 times longer life than conventional lead-acid batteries. Lithium batteries also have a lower weight, minimal self-discharge rate and zero memory effect.

✔️ Li-Ion lithium batteries: high energy density and fast charging

✔️ LiFePO4 lithium batteries: excellent durability and safety

It's up to you which lithium batteries you prefer. We hand-assemble compact lithium batteries of the AkuSet® or AkuBox® type from individual lithium cells, whether Li-Ion or LiFePO.
