Wiring sequence of lithium battery protection board:
Special attention: The wiring of different protective board manufacturers is not universal. Please ensure to use the correct wiring.
1. Ensure that the wiring is not inserted into the protective board at the front line.
2. The wiring starts from the black thin wire connecting "B -", the second wire (the red thin wire next to the black thin wire) is connected to the positive electrode B1 of the first string of batteries, and so on, and finally the red thin wire is connected to the total positive electrode of the battery.
3. After connecting the wiring, measure the voltage of the two adjacent metal terminals on the back of the plug. The ternary hybrid battery cell should be between 3.0V-4.2V, the lithium iron should be between 2.0V-3.6V, and the lithium titanate should be between 1.6V-2.75V.
4. After confirming the correct wiring sequence and voltage, insert it into the protective board socket,
5. Connect the "B -" (thick blue line) of the protective board to the total negative pole "D" (thick black line) of the battery, and connect it to the charging negative pole and the discharging negative pole.
