Description
VE. Bus BMS NG The VE.
Bus BMS NG is an all-in-one Battery Management System (BMS) for Victron Lithium NG batteries (not compatible with Lithium Battery Smart batteries), designed for systems with Victron inverters or inverter/chargers using VE. Bus communication.
It monitors and protects the batteries against overvoltage and under-voltage of any individual cell, and also against over-temperature or under-temperature conditions. With built-in Bluetooth, it connects directly to all lithium NG batteries in the system for central monitoring via VictronConnect.
It also receives current and state of charge data directly from the batteries, so there’s no need for a separate SmartShunt. The lithium NG batteries can be configured in series, parallel, or a combination of both, supporting 12V, 24V, and 48V systems.
A maximum of 50 batteries can be used in 12V or 24V banks, and 25 batteries in 48V banks, enabling up to 192 kWh (12V), 384 kWh (24V), and 128 kWh (48V) of storage. Multiple Lynx Smart BMS units can be paralleled to expand capacity and ensure redundancy.
Features: Bluetooth Smart: The VE. Bus BMS NG includes Bluetooth Smart for wireless configuration, monitoring, and firmware updates via the VictronConnect App.
Instant Readout shows key data such as SoC, battery temperature, warnings, and alarms directly in the device list, without needing to connect. Load disconnect output: Controls the remote on/off input of a BatteryProtect, inverter, DC-DC converter, or other loads with remote on/off functionality to prevent deep discharge.
Charge disconnect output: Controls the remote on/off port of chargers such as the Smart IP43 Charger, a Cyrix-Li-Charge relay, a Cyrix-Li-ct Battery Combiner, or a BatteryProtect, to prevent overvoltage. Pre-alarm output: Provides early warning for low battery voltage before disconnecting loads.
Can drive a relay, LED, or buzzer. Remote on/off control: Allows external control of both load and charge disconnect outputs.
LED indicators: Includes a

Electrical — frequently asked
- What’s the difference between marine wire and regular wire?
- Marine wire uses tinned (tin-coated) copper strands that resist the corrosion salt air causes, and it’s more finely stranded so it flexes with vibration without breaking. Standard automotive or household wire corrodes and fails much faster in a marine environment.
- How do I size a fuse for a marine circuit?
- Size the fuse to protect the wire, not just the device. Match the fuse rating to the wire gauge’s safe current capacity so the fuse blows before the wire overheats. When adding a new circuit, follow the wire manufacturer’s ampacity chart for the gauge and run length you’re using.
- Do I need a battery switch on my boat?
- A marine battery switch is strongly recommended. It lets you disconnect the battery for storage or service, isolate a failed battery, and — on multi-battery setups — choose which bank powers the boat. It’s a core safety and reliability component.
