As the name suggests, the battery protection board is mainly directed against rechargeable (generally refers to lithium batteries) the protective role of the integrated circuit board. Lithium battery (rechargeable type) so in need of protection, is determined by its own characteristics. Li-ion and Li-Polymer battery packs should always be used with a protection circuit to prevent the cell from over charging, over dis-charging, over current or short circuit. Choosing the correct circuit and applying it appropriately is vital to the longevity your batteries and your own safety.
