Note
This protection board cannot be used for Xenon lights, electric drill battery packs, electric fish machine battery packs, electric bicycle battery packs, children’s car batteries, motors, and 1W fisheye LED lights.
Note
For products with a current of more than 3A, the battery discharge rate should be more than 3C.
The magnification calculation formula:For a battery with a 1C magnification, the 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.
The battery will heat up during use, 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 (B+) strictly according to the diagram, don’t intentionally short circuit!
Note 2:After the line is connected, it needs to be charged before output.
Note 3:When connecting 4 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 then use them in series. During the discharge test, the battery with the fast voltage drop is a bad battery.
Note 4:Do not mix good batteries and bad batteries together! The closer the capacity/internal resistance of the 4 groups of batteries, the better! (2 good batteries + 2 bad batteries = 4 bad batteries) .
