The Victron smallBMS NG is a high-quality battery management system designed specifically for use with Victron Lithium Smart LiFePO₄ batteries. Whether you’re building an off-grid energy setup, powering a campervan, or managing a backup storage system, this compact unit ensures your lithium battery bank is always protected and performing at its best.
Designed with simplicity and efficiency in mind, the Victron smallBMS NG offers essential protection functions such as cell over-voltage, under-voltage, and over-temperature monitoring. It actively manages the battery’s state by disconnecting loads or chargers when critical thresholds are reached – preserving the lifespan of your batteries and safeguarding your energy system from potential damage.
Unlike more complex BMS units, the smallBMS NG is ideal for installations where space is limited and advanced features such as VE.Bus communication are not required. It features two outputs: “Load Disconnect” and “Charge Disconnect”, which can control external relays or BatteryProtect units. These allow the system to safely interrupt charging or discharging processes when needed, keeping your setup operating within safe limits.
The smallBMS NG is fully compatible with Victron Energy Smart Lithium NG batteries, supporting both 12.8V and 25.6V and 51.2V variants. It is easy to integrate and provides reliable operation in mobile, marine, and remote energy systems. Designed by Victron for seamless performance, this device forms a crucial link in any lithium battery system, ensuring both safety and longevity.
