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 stand-alone applications where efficiency and simplicity are paramount.

Simple, efficient and Bluetooth-enabled

Thanks to the integrated Bluetooth interface, a separate monitoring device like a SmartShunt isn't required. Using the VictronConnect app, you can conveniently view the charge level, battery voltage, and alerts on your smartphone or tablet at any time.
