Product Descriptions:

Li-Ion and Li-polymer battery packs must have a protection circuit model 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.

Features:

  • Keeps 22.2V Li-Ion Batery pack from overcharge and overdischarge.
  • Limit the Max Current to 8.0 A.
  • Designed for 6 Cells Li-ion /Li-polymer Battery Packs.
  • Battery Protection for 6 pcs battery cells in series.
  • With charging balancing function for cells ; balancing current is adjustable.
