5Pcs 3 Strings 12V18650 Lithium Battery Protection Board 11.1V 12.6V AntiOvercharge OverDischarge Peak 10A

1: The protection board cannot be used for lithium iron phosphate batteries, xenon lamps, hand drill battery packs, electric fish machine battery packs, electric bicycle battery packs, children's car batteries, motors above 775 (4A), 1W fisheye LED lights;
2: Suitable for massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring backup power supply, and other products.
3: Note: For products with a current above 3A, the battery discharge rate should be above 3C. Rate calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A upper limit working current.3C rate battery, 2000 capacity is equal to 2AH*3=6A upper limit working current.
4: The battery will heat up during use, that is, the battery rate is not applicable. In this case, it cannot be used for a long time, and the battery will be damaged quickly.
5: Do not mix good batteries with bad batteries! The closer the capacity/internal resistance of the 3 batteries is, the better! (The effect of using 2 good batteries + 1 bad battery = the effect of using 3 bad batteries)

Description Explanation:
3 strings (combination of 3 18650 batteries or polymer lithium batteries in series)
10.8V (rated voltage of polymer battery)
11.1V (rated voltage of 18650 or 3.7V lithium battery)
12.6V (voltage after lithium battery is fully charged)
Discharge 10A (referring to the upper limit discharge current limit)
Precautions
1: Strictly connect 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+) according to the diagram, do not intentionally short-circuit!
2: After the line is connected, it needs to be charged first, and then there will be output.
3: When connecting 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same, if not, please fully charge each group of batteries separately and then use them in series. During the discharge test, the group of batteries with a rapid voltage drop is the poor battery.
