BMS 8S 25.6V 100A Lifepo4 Battery Management System with Balance and Temperature Sensor, Screws and Wires,Common Port, Aluminum Substrate for Lifepo4 Battery Pack

NoticeBefore installing the BMS protective board, it is necessary to match the voltage, capacity, and internal resistance (the voltage difference between the battery per section is not higher than 0.05V, the difference between the internal resistance is not more than 5M, and the capacity difference is less than 30mAh). When connecting to the BMS for the first time, the cell voltage needs to be lower than 3.3V. If the battery voltage difference is too large, the battery pack will not be able to charge.
Wiring MethodThe wiring methods of Common ports of BMS: B- connection battery pack negative, C- connection charging negative/output negative. All the positive electrodes are the total positive pole from the battery pack. Repair and assembly are only recommended for personnel with professional electrical knowledge
High Quality's BMS utilizes top quality (A-level) protective integrated circuit IC, from the solution of Industry car level. BMS manufactured by high quality Mos and IC.

Please note:
Our products use the integrated IC solution.
It means that the SOC accuracy of the BMS is very high, and the voltage of each string will be collected. It must be required that the voltage, internal resistance, and capacity must be the same height during assembly, otherwise the BMS will disconnect and protect (disconnection protection function).
When connecting to BMS for the first time, the cell voltage must be lower than 3.3V. If it exceeds 3.4V, it will easily trigger the overcharge protection and the BMS will not be activated.
This product is an industrial semi-finished product, which needs to be repaired and assembled by people with professional electrical knowledge. Thank you for your understand.
