If you’re into off-grid power setups, boats, or camper vans, you know how important it is to keep your batteries safe and in top shape. The VE.Bus BMS NG is Victron’s all-in-one battery management system made specifically for their Lithium NG batteries (just a heads-up, it doesn’t work with Lithium Battery Smart batteries).
This little powerhouse keeps an eye on every single cell in your battery pack — protecting them from getting overcharged, drained too low, or damaged by temperature swings. It works seamlessly with Victron inverters and inverter/chargers that talk over VE.Bus communication.
What makes it super handy? It has built-in Bluetooth, so you can check on your batteries right from your phone using the VictronConnect app — no extra gadgets needed. It also pulls info like how much charge you’ve got left and how much current is flowing, straight from the batteries.
Whether your setup is 12V, 24V, or 48V, and whether you wire your batteries in series, parallel, or both, the VE.Bus BMS NG has you covered. You can connect up to 50 batteries in smaller systems, or up to 25 in 48V setups — that’s plenty of power for any serious off-grid adventure or DIY energy project.
