ATTENTION——

1. It is strictly forbidden to insert balance wires into BMS before connecting batteries.Must make sure that the cable is soldered correctly first , and then connect the BMS board.

2. The sequence of connecting wires for BMS:

a.From thin black balance wire to stare, the 2ndwire(thin red wire)connect with the 1stbattery’s positive pole.Then connect each cell’s positive pole in order until the last one B+.
b.Please do not insert the plug directly after the cable is connected.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 ~4.2V, and the voltage of the iron-lithium battery should be between 2.0 ~3.6V. The voltage should be between 1.5~2.75V.
c.After confirming that the wiring sequence and voltage of the cables are correct, insert them into the socket of the protection board.

Attentionplease: The cables of different manufacturers are not universal, please make sure to use the matching cables.

3. After the wiring is completed, measure whether the voltage of battery B+and B- ,andthe voltage of B-and C- are equal. If they are equal, the protection board is working normally and can be used normally. If it is not equal, please check the wiring again.
