Bisida BMS 20S 72V 40A Lithium PCB Protection Board with Balance Wire and NTC, Common Port, Lithium-Ion Battery Management System

Why it's a great deal

• 【Multiple Protection】BMS has a variety of protection functions, such as Overcharge Protection, Overdischarge Protection, Overcurrent Protection, Short circuit Protection, Temperature Protection, Disconnection protection,Balance protection

• 【Operating Temperature】Bisida's BMS Lithium Ion supports (3.7V) lithium-ion battery charging and discharging in zones from 2.65V to 4.25V, with low temperature protection up to -20°C and high temperature protection up to 70°C.

• 【Notice】Before 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 5MΩ, 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 3.9V. If the battery voltage difference is too large, the battery pack will not be able to charge.

• 【Wiring Method】The wiring methods of Common ports of BMS: B- connection battery pack negative , P- 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】Bisida'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 .
