Features:
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 board is specially designed for 18.5v Li-Ion Battery packs made of Li-ion and Li-Polymer cells.
- Keeps 18.5V Li-Ion Battery packs from overcharge and over discharge
- Limit the Max discharge Current to 8.0 A.
- Designed for 5 Cells Li-ion /Li-polymer Battery Packs
- Li-ion/Polymer Battery Protection
- SEIKO S8233 Protection IC
- IR IRF4906, FDS9926 MOSFET
- Dimension: 108mm x 40mm x 10mm
