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.
