1. This protection board can not be used for iron-ion polymer batteries, hand drill battery packs, electric fish machine battery packs, electric bicycle battery packs, 2 pieces in series with 24V use, 775 (4A) or higher motors, 1W fisheye LED lights, Please pay attention to customers who purchase the above combination!
2. For products with a current above 3A, the battery discharge rate must be above 3C. Magnification calculation formula:
For a battery with 1C rate, the capacity of 2000 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.
3. The battery will heat up during use, which means that the battery rate is not applicable. In this case, it must not be used for a long time, and the battery will be damaged quickly.
4. Connect 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+) strictly according to the diagram, and do not short-circuit. After the line is connected, it needs to be charged before output. 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 fast voltage drop is a bad battery.
