Operation Notes:
It is strictly prohibited to weld the cable with the protective plate connected. Before connecting the protective plate, you must first confirm that the cable is welded correctly.
The wiring sequence of connecting the protective board to the battery is as follows:
1. The wiring starts from the black wire connected to -, the second wire (white wire) is connected to the positive terminal of the first string of batteries, and then connected to the positive terminal of each string of batteries in turn, until the last string of +;
2. After connecting the cable, please do not insert the plug directly. First measure the voltage between each two adjacent metal terminals on the back of the plug. If it is a ternary polymer battery, the voltage should be between 3.0 and 4.2V. For lithium iron battery, the voltage should be between 2.0 and 3.6V. For lithium iron titanate battery, the voltage should be between 2.0 and 3.6V. The voltage should be between 1.5~2.75V;
3. After confirming that the wiring sequence and voltage of the cables are correct, insert them into the protective board socket.
Special note: Cables from different manufacturers are not universal, please make sure to use matching cables.
Common Uses:
