  • Keep 22.2V Li-Ion Batery pack from overcharge and overdischarge
  • Limite the Max Cuurent to 8.0 A.
  • Designed for 6 Cells Li-ion /Li-polymer Battery Packs
  • Battery Protection
  • Adopt SEIKO S8233 Protection IC
  • Adopt IR IRF4906, FDS9926 MOSFET
  • Dimension: 2.6" x 1.7" inch

PCB Indications

  • B+ Battery (+)
  • B- Battery (-)
  • P+ OUT (+) /Load (+)
  • C+ OUT (+) /Charge (+)
  • P- OUT (-) /Charge(-) / Load(-)
