Note: The lithium battery protection board cannot be used for lithium iron phosphate batteries, hernia lights, hand drill battery packs, electric fish machine battery packs, electric bicycle battery packs, children's car batteries, power motors above 550, and 1W fisheye LEDs. Lamps, please pay attention to customers who purchase the above combination! .
The power range described is applicable to the following products:
Massager battery pack, LED lamp backup power supply, 12V electronic products, solar street lamp battery pack, monitoring backup power supply, and other products.
Note: For products with a current above 3A, the battery discharge rate must be above 3C.
The magnification calculation formula: for a battery with a 1C magnification, the capacity of 2000 is equal to 2AH*1=2A working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A working current.
In use, the battery will heat up, which means that the battery rate is not applicable. In this case, the battery cannot be used for a long time, and the battery will be damaged quickly.
Note 1: Wiring 0V(B-), 3.7V(B1), 7.4V(B2), 11.1V(B3), 14.8V(B4), 18.5V(B ) strictly according to the diagram, don't short-circuit intentionally!
Note 2: After the line is connected, it needs to be charged before output.
Note 3: When connecting 5 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please charge each group of batteries separately and then use them in series. During the discharge test, the battery with the fastest voltage drop is the poor battery.
Explain: Don't mix good batteries and bad batteries together! The closer the capacity/internal resistance of the 5 sets of batteries, the better! (3 good batteries 2 bad batteries = 5 bad batteries).
