Package List:
1 x Lithium Battery Protection Board
Note:
1. This protective board cannot be used for iron ion polymer batteries, hand drill battery packs, electric fishing machine battery packs, electric bike battery packs. Two pieces can be connected in series with 24V, and a 1W fisheye LED light can be used
2. For discharge products above 3A, the battery discharge rate should be more than 3C.
Discharge rate calculation formula: 1C rate battery, 2000 capacity is equal to 2AHx1=2A working current; 3C rate battery, 2000 capacity is equal to 2AHx13=6A working current. If battery heats during use, it means the battery discharge rate is not applicable, this situation can not be used for a long time, or the battery will be damaged quickly.
3. In strict accordance with the wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+), do not intentionally short circuit!
4.After connecting the cable, it needs to be charged first before there will be output.
5. When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please fill each set of batteries separately and then use them in series. During the discharge test, the battery with the fastest voltage drop is the poor battery.
6.Tips: Do not mix good battery and poor battery to use! The closer the capacity/internal resistance of the batteries are, the better! (The use effect of 2 good batteries and 1 poor battery = the use effect of 3 poor batteries).
