Protective board connection battery wiring:nn* Special attention: The wire cable of different manufacturers are not same standard, please make sure to use he matching cables; the colors of B- and P- lines of different manufacturers are different, please pay attention to the B- and P- marks.nn1. Remember!!! When welding sampling wire cable, do not insert the cable into the BMS.n2. The cable connects the total negative electrode B-from the fine black line. The second wire (red wire) is connected to the positive pole of the first string of batteries.Connect the positive electrode of each string of batteries in turn until the last wire cable of the total positive B+.n3. After the cable is connected, do not insert the plug directly into the BMS.First measure the voltage between each two adjacent metal terminals on the back of the plug. If it is a ternary lithium battery, the voltage should be between 3.0~4.15V, and the iron-lithium battery should be 2.5~ Between 3.6V, lithium titanate battery should be between 1.8-2.8V, make sure the voltage is correct before proceeding to the next step.n4. Receive the BMS B-line (blue thick line) to the total battery negative electro-de (B-line length should not exceed 40cm).n5. Insert the wire cable into the BMS.nnAfter the wiring is completed:nn1. Measure whether the voltage of battery B+, B- is equal to the voltage of B+ and P- (that is, whether the voltage of the battery pack itself is e- qual to the voltage after passing through the protection board, if they are equal, the BMS is working normally, which can be used normally. If not, please follow Re-check the queue of the wiring above.n2. The positive electrodes of the charging and discharging end are all directly connected to the total positive pole B+ of the battery; the wiring method of the same port BMS is that the charging and discharging negative poles are connected to the P- point of the BMS; the wiring m- ethod of the branch BMS is the negative pole of charging Connected to C-, the negative electrode of discharge is connected to P-.n3. Finally, if you have any questions, please contact the customer service to help you solve it.
