Discover the most advanced lithium battery management system on the market – the 123\SmartBMS G3. This modular, wirelessly controlled BMS is designed to protect and optimize your LiFePO₄, LTO, or other lithium battery packs down to every single cell.
Why choose the 123\SmartBMS G3?
✅ Maximum Battery Protection
The system continuously monitors voltage, temperature, and current for each cell individually. If limits are exceeded, built-in relays automatically disconnect charging or load to ensure safe operation.
✅ Passive Cell Balancing
With a 1A balancing current, the BMS keeps your cells perfectly balanced, extending battery life and ensuring peak performance.
✅ Modular System Without Compromise
Managing 4 or 200 cells? No problem. The 123\SmarBMS G3 grows with your battery pack — just add intermediate modules to expand your system easily.
✅ Advanced Bi-Directional Current Measurement
Equipped with high-precision sensors, it measures both charge and discharge currents, giving you complete insight into your battery’s State of Charge (SoC) and State of Health (SoH).
✅ Bluetooth Control and Free Mobile App
Full monitoring and configuration is done conveniently via a free mobile app (Android/iOS). Check cell voltages, currents, charge status, and historical data anytime, anywhere.
✅ Full Compatibility with Victron GX Systems
Connect the BMS via USB cable to Victron Cerbo or Venus OS platforms. Battery data is integrated into your energy system and accessible via the Victron Remote Management (VRM) portal.
✅ Robust Design and Operating Temperatures from −40 °C to +85 °C
High-quality components and durable construction allow use in demanding environments — perfect for off-grid, industrial, and solar applications.
