TECNOIOT 1PCS 8S 24V 20A LiFePO4 Lithium Battery Protection Board BMS PCB with Balance

【8S 20A LIfEPO4】☆☆☆8S 24V 20A LiFePO4 Lithium Battery Protection Board BMS PCB Board with Balance☆☆☆The cable from different manufacturers is not universal, please make sure to use the matching cable;✔1. Before connecting the cable, make sure that the cable is not inserted into BMS first; 【Easy operation-1】✔2. The cable is connected from the thin black line to B-, the second line(thin red line) is connected to the positive pole of the first string of batteries, and the remaining ones are connected to the positive pole of each string of batteries in turn until the last string B+; 【Easy operation-2】✔3. After the cable is connected, do not insert the plug directly. Measure the voltage between each two adjacent metal terminals on the back of the plug. If the voltage of the ternary polymer battery should be between 3.0v to 4.2v, the iron-lithium battery should be at 2.0v to 3.6v, lithium titanate battery should be between 1.5v to 2.75v; 【Easy operation-3】✔4. Check the voltage of the corresponding serial number between the adjacent lines by the multimeter, and then insert the BMS socket; 【Easy operation-4】✔5. Finally, connect the protection board B-line (blue thick line) to the battery negative pole.
