Based on Zhongying SH3676010B 7-10 series 30A lithium battery protection board

 With the widespread application of lithium batteries in the communications industry, high performance, high reliability, and high cost-effectiveness are required for battery management systems. This product is a BMS specifically designed for power batteries, employing an integrated design. This solution is an intelligent semi-software hardware board that can implement overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, and charge/discharge temperature protection.
This solution uses the Zhongying SH3676010B and can be programmed using a host computer.
Product Features:

Supports all customizable parameters, which can be written via a host computer; includes serial communication for connecting to a host computer to read battery pack information and write parameters;
supports intelligent all-time balancing, performing balancing during charging and resting, extending balancing time to improve balancing efficiency; incorporates differential pressure start balancing conditions to prevent evenly balanced cells from becoming unbalanced due to improper balancing methods, achieving 5-10 times better balancing performance than traditional methods (optional);
supports writing product numbers for easy production management and traceability (optional)
; includes load and charging checks to prevent damage to charging or discharging MOS under specific conditions; supports same-port low-voltage switch; includes
voltage detection and disconnection protection.

Function Description:

7-cell series protection;
same-port charging/discharging port;
supports undervoltage sleep mode; low-power mode (requires charging activation);
can achieve overvoltage and undervoltage protection for any cell in the battery pack;

discharge overcurrent and short-circuit protection; recovers after protection by disconnecting the load or inserting the charger.
