3 sorozatú 12V18650 lítium akkumulátorvédő kártya 11,1V 12,6V, kiegyensúlyozott 25A túláram-, túltöltés- és túlkisülés-védelemmel
3 series 12V18650 lithium battery protection board 11.1V 12.6V with balanced 25A overcurrent, overcharge and overdischarge prote
Note: This 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, motors above 775 (4A), 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 (B ) strictly according to the diagram, do not intentionally short-circuit!
Note 2: After the line is connected, it needs to be charged before output.
Note 3: When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are not the same, please charge each set 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 batteries and bad batteries together! The closer the capacity/internal resistance of the 3 sets of batteries, the better! (2 good batteries 1 bad battery use effect = 3 bad batteries use effect).
