2S 7.4V 8A BMS PCB Battery Protection Board For 18650 Li-ion Lithium-Ion Battery In Pakistan

A battery management system (BMS) is an electronic regulator that monitors and controls the charging and discharging of rechargeable batteries. Battery BMS protection boards are the brains behind battery packs. 2S 8A BMS manages the output, charging, and discharging and also provides critical safeguards to protect the batteries from damage. 18650 protection circuit Board is a high-accuracy voltage detection circuit. The 8A protection board can not be used for lithium-ion batteries.
