Victron smallBMS NG – Compact Battery Management System for Victron Lithium NG Batteries

The Victron smallBMS NG is a compact, intelligent battery management system for the safe monitoring and control of Victron Lithium NG batteries – specifically for systems without VE.Bus components such as MultiPlus or Quattro. It protects the batteries from deep discharge, overcharging, and critical voltage levels, and is ideal for standalone applications where efficiency and simplicity are paramount.

Simple, efficient, and Bluetooth-enabled

Thanks to the integrated Bluetooth interface, no separate monitoring device such as a SmartShunt is required. Using the VictronConnect app, you can conveniently view the state of charge, battery voltage, and warnings on your smartphone or tablet at any time.
