11.1V 12.6V 8A 3S Lithium Battery Protection PCB BMS Board

This 3 cell lithium ion battery protection board is equipped with Japan battery control IC and 9622A MOSFET protection IC with over charging, over discharging, over current and short circuit protection. It is perfect for li-ion lipo battery cell pack such as 18650,18550, 14500 avoiding the damage during charging or discharge then prolong their lifetime. This lithium-ion BMS is compact, economical, and ensures the safe operation of low voltage lithium-ion battery packs. This standalone BMS controller was designed specifically for consumer electronics, to automotive standards. No additional equipment is needed for the safe operation of lithium-ion battery packs. It ensures that battery pack safety is always maintained and cell lifetime is maximized by avoiding high temperature events that deteriorate cell performance. The BMS passively balances the charge between all cells in the battery pack which maximizes the runtime of the battery pack and extends its life.
