Product Name
Intelligent BMS protection board | 200A power battery dedicated | First choice for power tools/energy storage system
Pain point solution
Inconsistent battery cells lead to capacity attenuation --- Passive balancing technology achieves ±0.05V voltage balance and improves battery pack efficiency.
System downtime in high temperature environment --- Wide temperature range design (-20℃~75℃) with aluminum alloy heat dissipation shell to ensure stability in extreme working conditions.
Lack of communication monitoring → Optional Bluetooth/UART interface to view battery status (voltage, temperature, SOC) in real time.
Industry application
Electric transportation: Electric scooters, golf carts (compatible with 10A-30A discharge requirements)
Home energy storage: Solar power system, RV power supply (supports TVS surge protection design)
Emergency equipment: UPS power supply, medical equipment (short circuit self-recovery function)
Current integration technology
Calculate the remaining power (SOC) through real-time current accumulation, with an error of <3%, eliminating the problem of false power.
Wireless communication expansion (customizable)
Support 4G/Bluetooth module (optional) to achieve remote battery status monitoring (voltage, temperature, SOC) and cloud data synchronization

Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
