4S 8A lifepo4 12.8V 18650 BMS PCM battery protection board bms pcm for lifepo4 battery cell pack with balancing
This BMS used Japan lifepo4 rechargeable battery protection IC It can also used for 4s battery packs.
1) high-accuracy voltage detection circuit;
2) terminal of the charger using high voltage device;
3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);
4) MOS transistor can control the battery charge and discharge; 5) low standby current consumption.
3S BMS Connection instruction: B+ connected battery positive; B1 connect the point between 1 and battery 2; B2 connect the point between battery 2 and battery 3; B3 connect the point between battery 3 and battery 4 B- connect battery negative end P- connection charge/discharge negative P+ connect charge /discharge positive Notice: 1) Please note that the input and output voltage, and load current conditions for power protection board does not exceed the electrical parameters of the allowable power consumption; 2) special attention to the load current can not work long hours between maximum continuous operating current and over-current protection current; 3) When connecting the battery ,it may not discharge. In this case, connect the charger can be restored to normal working condition; 4) Although the BMS built-in electrostatic protection circuit, but please do not hand touch when BMS in the working condition, so as to avoid damage from static electricity protection board.
