The Victron VE.Bus BMS NG is a BMS built for Victron Lithium NG batteries. It is aimed at systems that pair Victron inverters or inverter/chargers with VE.Bus communication, and it cannot be paired with Lithium Battery Smart batteries. Built-in Bluetooth gives monitoring through VictronConnect, and a pre-alarm output warns of low battery voltage before loads disconnect. It accepts 9 to 70 V DC input, has an IP20 enclosure, and supports banks of up to 50 batteries at 12V or 24V.
Our take
This BMS can't be paired with Lithium Battery Smart batteries, so an existing Smart bank rules it out and the battery choice has to come first. Its pre-alarm output gives early warning of low voltage before loads are disconnected.
From our buying guide
BCI defines a battery management system as an electronic system that monitors a battery's condition, performance and health. Some lithium batteries have one built in and some need an external unit.
Check before you buy:
- Battle Born warns that a BMS shutdown leaves the vessel without power, and that one during alternator charging can severely damage the alternator.
- There is no one low-temperature limit for charging lithium, so take it from the manual for the battery you have.
