Custom 3 strings of 11.1V 12V 12.6V lithium battery protection board with overcharge and overdischarge short circuit function 10A curre

Attention:

This protection board can not be used for iron polymer battery, hand drill battery pack, electric fish battery pack, electric bicycle battery pack, 2 pieces of 24V in series, 775(4A) or more motor, 1W fisheye LED lamp, for the above combination purchase customers please pay attention! .

The described power range is suitable for the following products:

Massager battery pack, LED lamp backup power supply, 12V electronics, solar street lamp battery pack, monitoring backup power supply, and other products.

Note: For discharge products above 3A current, the battery discharge ratio should be above 3C.

Rate calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A upper limit operating current.

3C rate battery, 2000 capacity equal to 2AH*3=6A upper limit operating current.

In the use of the battery will heat is the battery ratio is not applicable, this situation must not be used for a long time, the battery will soon be damaged.

Note 1: Wire 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+) strictly according to the diagram, do not intentionally short circuit!

Note 2: After the cable is connected, it needs to be charged first before there will be output.

Note 3: When connecting three groups of batteries in series, ensure that the voltage of each group of batteries is the same. If the voltage is different, please charge each group of batteries separately and use them in series. The voltage drops during the discharge test. The fast battery is the differential battery.

For some customers with poor electronic foundation, please explain: do not mix good batteries with poor batteries! The closer the capacity/internal resistance of the 3 batteries, the better! (The use effect of 2 good batteries +1 poor battery = the use effect of 3 poor batteries).
