Protection Circuit Module ( PCB ) for 22.2V Li-Ion Battery Pack (6 cells with 8A limit )

Li-Ion and Li-polymer Battery packs must have a protection circuit module to keep Li-Ion/Polymer Battery from over charge, over discharge, and to prevent accidental battery explosion due to its extra high energy density. This protection circuit is specially designed for 22.2V Li-Ion Battery packs made of Li-ion and Li-Polymer cells.

• Keeps 22.2V Li-Ion Batery pack from overcharge and overdischarge
