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. 8A 2S 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.

Features Of 2S 8A BMS Protection Circuit Board For 18650 Lithium Battery:

• A high-accuracy voltage detection circuit
• 2 series 7.4V lithium battery
• A terminal of the charger using a high voltage device
• Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit)
• MOS transistor can control the battery charge and discharge
• low standby current consumption.
