Preventive measures: 
1. Lithium battery protection board is made of iron phosphate, xenon lamp, hand drill battery, pack of electric fish battery, baby car? Battery, 550+ power motor, 1W fisheye LED lamp, can not be used for customers. Those who buy the combination above should pay attention to the following products.


2. For discharge products exceeding 3A, battery discharge rate must be greater than 3C. Magnification: 1C rate battery, 2000 capacity is 2AH * 1 = 2A working current, 3C rate battery, 2000 capacity equals 2A * 3 = 6A working current. When in use, the battery becomes hot or the battery rate is not applied. After long-term use, the battery will be damaged immediately.


3. After connecting the line, you need to charge it first to get the output.


4. When connecting 6 pairs of batteries in a row, make sure each pair of batteries is the same. If not, please put each battery separately and use it in sequence. During discharge testing, the biggest voltage drop is a bad battery.


5. Do not mix good batteries with bad batteries! The closer the internal resistance of a 6-cell battery, the better it is. (4 good batteries + 2 bad battery effect = 6 bad battery effect) Please strictly follow the wiring of the connection diagram. Intentional short circuit!
