Lithium battery protection board can not be used for lithium iron phosphate battery, xenon lamp, hand drill battery pack, can not be used for electric fish battery pack, electric bicycle battery pack, children’s car battery, 550 or more power type motor, 1W fisheye LED light, Customers who use the above combination purchases should pay attention! .
The power range described applies to the following products:
Massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring standby power supply, and other products.
Note: For discharge products above 3A, the battery discharge rate should be more than 3C.
Magnification calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A working current.
In the use of the battery will be hot, the battery rate is not applicable, this situation can not be used for a long time, the battery will be damaged quickly.
Note 1: Wiring according to the diagram is 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B4), 18.5V (B5), 22.2V (B+), Do not intentionally short circuit!
Note 2: After the line is connected, it needs to be charged before it will have output.
Note 3: When connecting 6 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are different, please fill each group of batteries separately and use them in series. During the discharge test, the battery with the fastest voltage drop is the poor battery.
Explain: Do not mix good battery and poor battery! The closer the capacity/internal resistance of the 6 batteries is, the better! (4 good batteries + 2 poor battery use effect = 6 poor battery use effect).
6 strings (for 6 18650 batteries or polymer lithium batteries in series)
21.6V (rated voltage of polymer battery)
22.2V (rated voltage of 18650 or 3.7V lithium battery)
25.2V (voltage after the lithium battery is fully charged)
Discharge 22A (refers to the upper limit discharge current limit)
