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 prevent accidental battery explosion due to its extra high energy density. This protection circuit board is specially designed for 18.5v Li-Ion Battery packs made of Li-ion and Li-Polymer cells.
Keep 18.5V Li-Ion Battery packs from overcharge and over discharge
Limit the Max discharge Current to 8.0 A.
