Victron smallBMS NG - BMS400100300

Overview

The Victron smallBMS NG with Pre-Alarm is a compact and cost-effective Battery Management System designed exclusively for Victron Lithium NG (LiFePO₄) batteries. It provides essential monitoring, protection and control functions for battery banks without the complexity of VE.Bus integration.

Offering a simpler alternative to the VE.Bus BMS NG, the smallBMS NG is ideal for systems that do not require VE.Bus-compatible inverter/chargers such as MultiPlus or Quattro. It supports large, scalable battery configurations while maintaining robust protection and early warning capabilities.
