Victron Lynx Smart BMS 500 (M10) for Lithium Battery Smart 12/24/48V

The Victron Lynx Smart BMS 500 (M10) (MPN: LYN040102100) is a battery management system for Victron Lithium Battery Smart batteries in 12-, 24-, and 48-V systems. It combines a 500 A main contactor, a pre-charge circuit, and a battery monitor with interfaces for controlling and monitoring the battery bank. The BMS is intended exclusively for the compatible Victron battery series and does not replace the required external system protection.

Control, Protection, and System Integration

• Integrated main contactor rated for 500 A continuous current and 600 A for up to 5 minutes
• Pre-charge circuit to limit high inrush currents for capacitive loads
• Battery monitor for state of charge, voltage, current, status, and history data
• Bluetooth for configuration and monitoring via VictronConnect
• VE.Can connectivity for GX devices and monitoring via the VRM portal
• DVCC and ATC/ATD contacts for controlling compatible chargers and loads
• Monitoring of fuses for up to four connected Lynx distributors
• M10 busbar connections for integration into the Lynx distribution system

Protection functions for the battery bank

The BMS monitors the status reports from the connected smart batteries and controls chargers and loads based on the detected cell voltages and temperatures. A configurable pre-alarm warns of an impending shutdown due to low cell voltage. The integrated protection provides an additional layer of safety in case chargers or loads are not deactivated in time via DVCC or the ATC/ATD contacts. Appropriate external circuit protection remains necessary.

Pre-charging and Battery Data

The integrated pre-charge circuit charges capacitive loads in a controlled manner before the main contactor closes. This limits high inrush currents when inverters or inverter-chargers are switched on. The built-in shunt measures the current flow and, together with the monitoring electronics, provides data such as state of charge, voltage, current, and system status.

VictronConnect, GX, and Lynx System

Settings and operating data can be accessed via Bluetooth using VictronConnect. A GX device connected via VE.Can expands the system to include a central display, DVCC control, and remote monitoring via the VRM portal. The BMS can be connected to Lynx distributors to form a continuous DC distribution system; however, with appropriate system design, it can also be operated without additional Lynx modules. Up to 20 compatible batteries can be managed by a single BMS. For redundant systems, up to five BMS units with the same rated current can be operated in parallel under the documented conditions.
