Lithium-ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, no memory effect, and only a slow loss of charge when not in use. Beyond consumer electronics, LIBs are also growing in popularity for military, electric vehicle and aerospace applications.

We do sell Li-Ion-Batteries exclusively as "Packs", that means that we do not sell Li-Ion-Battery bare cells. So called "Packs" are even single cells with safety unit.
The datasheets of the single cells are just for information.
