The Victron smallBMS NG is a compact, intelligent Battery Management System for the safe monitoring and control of Victron Lithium NG batteries – especially for systems without VE.Bus components such as MultiPlus or Quattro. It protects the batteries from deep discharge, overcharge and critical voltage values and is ideal for off-grid applications where efficiency and simplicity are paramount.
Simple, efficient and Bluetooth-enabled
Thanks to the integrated Bluetooth interface, no separate monitoring device like a SmartShunt is required. Via the VictronConnect App, you can view the state of charge, battery voltage and warnings conveniently on your smartphone or tablet at any time.
