Victron Energy Lynx Smart BMS 500 NG (M10) Battery Management System for Lithium NG Batteries

Lynx Smart BMS 500 NG (M10)

The Lynx Smart BMS NG is a dedicated Battery Management System (BMS) designed specifically for the Victron Lithium NG batteries. These batteries utilize Lithium Iron Phosphate (LiFePO4) technology and are available in 12.8 V, 25.6 V, and 51.2 V variants with various capacities. They can be configured in series, parallel, and series/parallel arrangements, allowing for the creation of battery banks with system voltages of 12V, 24V, or 48V. The maximum number of batteries in a single system is 50, enabling a maximum energy storage of 192kWh in a 12V system and up to 384kWh in a 24V and 48V system. For comprehensive details about these batteries, visit the Victron Lithium NG battery product page.

Out of the various BMSes available* for the Lithium NG batteries, the Lynx Smart BMS NG is the most feature-rich and complete option and integrates seamlessly with other M10 products in the Lynx Distributor system. It is available in 500 A (M10) and 1000 A (M10) versions¹).

• ATC/ATD contacts can be used to control other chargers and loads that have a remote on/off port

Programmable Relay

• Can be used either as an alarm relay (combined with the pre-alarm) or to control an alternator via its external regulator (ignition cable)


• Features Alternator ATC mode for safe alternator disconnection before battery disconnects

AUX Terminal

• Onboard auxiliary power supply (1.1 A @ system voltage) for powering specific loads (i.e. a GX device) post-BMS shutdown


• Automatic shutdown of BMS and AUX connection if no charge voltage is detected within 5 minutes after a low voltage event

VE.Can and NMEA 2000 Data Communication

• Easy connection and communication with GX devices via VE.Can using a standard RJ45 network cable


• Integration into marine networks via NMEA 2000 protocol (requires a VE.Can to NMEA 2000 micro-C male cable)

Lynx Distributor Fuse Monitoring

• Monitor fuse status of up to 4 connected Lynx Distributors via VictronConnect or GX devices


• Receive alarms in case of blown fuses

¹) Up to 5 BMS-es can be paralleled. This requires a firmware update, expected in Q3 2024.
