The Victron Lynx Smart BMS 500 (M10) is a battery management system built for Victron lithium (LiFePO4) battery banks. It combines cell protection, system control and communication in one bus-bar mounted unit, suited to professional off-grid, marine and vehicle installations that need a compact, integrated BMS.

Key features

• 500A continuous DC current rating with M10 busbar connections.
• Integrated cell protection against over-voltage, under-voltage, over-temperature and over-current at the battery level.
• Communicates with Victron GX devices (Cerbo GX, Venus GX) over VE.Can for system monitoring and control.
• Automatically controls charge sources and loads, disconnecting non-critical circuits when battery limits are reached.
• Mounts directly onto the Victron Lynx busbar system for compact DC distribution.
• Configured and monitored through the VictronConnect app via Bluetooth.

Product overview

The Lynx Smart BMS 500 sits at the centre of a Victron lithium battery system, handling both protection and communication. Rather than simply disconnecting on fault, it can instruct a MultiPlus, Quattro or MPPT charge controller to reduce or stop output before a hard disconnect occurs, protecting the battery and the connected equipment.

The M10 designation refers to the busbar connection bolt size, confirming compatibility with the Lynx busbar system. At 500A it suits larger battery banks used in off-grid cabins, commercial vehicles, narrowboats and marine vessels. The VE.Can interface reports cell-level data to a GX device, viewable remotely through the VRM portal. The unit weighs 2 kg and mounts within the Lynx modular busbar enclosure.

Applications

• Off-grid cabin or lodge systems using Victron Smart Lithium battery banks.
• Marine and narrowboat DC systems needing integrated BMS and monitoring.
• Commercial vehicle and motorhome conversions with high-capacity lithium installations.
• Industrial off-grid systems requiring remote monitoring via VRM.
• Hybrid solar systems combining MultiPlus or Quattro inverter/chargers with lithium storage.

What's included

• 1x Victron Lynx Smart BMS 500 (M10) unit

Installation notes

Installation should be carried out by a qualified electrician or experienced Victron installer. Full BMS communication and control requires Victron Smart Lithium batteries and a compatible GX device, such as Cerbo GX, connected via VE.Can. Connections must be torqued to the M10 specification with appropriate DC fusing fitted upstream. This product is for DC lithium systems, not grid-tied AC use, and does not require G98 or G99 compliance.
