Lynx Smart BMS 500 NG (M10)

The Lynx Smart BMS 500 NG (M10) is an advanced battery management system (BMS) designed specifically for Victron Energy’s lithium NG (next-generation) batteries. It monitors, controls, and protects your lithium-iron-phosphate (LiFePO4) battery bank by tracking state of charge and preventing deep discharge and overcharging. It also includes a safety contactor and battery controller.

The Lynx Smart BMS 500 NG (M10) is compatible with system voltages of 12 V, 24 V or 48 V. It is designed to adapt to different battery bank configurations.

This BMS allows a maximum energy storage capacity of 192 kWh for a 12 V system, and up to 384 kWh for a 24 V or 48 V system. This capacity can be increased by connecting multiple Lynx Smart BMS NG units in parallel.

You can connect up to 50 x 12 V or 24 V batteries, or up to 25 x 48 V batteries to a single Lynx Smart BMS 500 NG (M10).

Yes, the parallel redundancy function allows integrating multiple Lynx Smart BMS NG units into the same installation. Each BMS manages its own battery bank, and together they form a redundant battery system. Up to 5 BMS units can be connected in parallel.

The Lynx Smart BMS 500 NG (M10) integrates a 500 A continuous (600 A peak for 5 minutes) safety contactor. It serves as a secondary safety mechanism to protect the battery in case of primary control failure (ATC, ATD and/or DVCC). It can also be used as the main system switch, remotely controllable.

Yes, the Lynx Smart BMS 500 NG (M10) is equipped with an integrated precharge circuit. This circuit prevents excessive inrush currents when connecting capacitive loads, such as inverters, eliminating the need for external precharge devices.

The Lynx Smart BMS 500 NG (M10) integrates a battery controller that provides real-time monitoring of state of charge (SoC), voltage, current, and historical data. This information can be accessed via the VictronConnect app (Bluetooth) or a GX device (such as the Cerbo GX) and the VRM portal. An instant read function enables quick diagnostics.

The BMS communicates via Bluetooth (for VictronConnect) and VE.Can (using a standard RJ45 network cable for GX devices). Since the CAN-bus protocol is based on NMEA 2000, it can also integrate into a marine network and feed your marine MFD with data, requiring a male micro-C VE.Can to NMEA 2000 cable.

Victron compatible battery chargers, battery chargers/inverters, and solar chargers are automatically controlled via a GX device connected to the DVCC. Additionally, the ATC (Allow-to-Charge) and ATD (Allow-to-Discharge) contacts can be used to control other chargers and loads with a remote on/off port.

Yes, the Lynx Smart BMS 500 NG (M10) has a pre-alarm signal. This signal provides a warning before the system shuts down due to low cell voltage. The pre-alarm mode is configurable via the programmable relay.

The AUX port provides an auxiliary power output (1.1 A at system voltage). It is useful for powering specific devices, such as a GX device, after the BMS has disconnected consumers in case of low cell voltage. If no charging voltage is detected within 5 minutes of this event, the BMS, including the AUX connection, shuts down.

The Lynx Smart BMS 500 NG (M10) integrates seamlessly with the Lynx distribution system, being specifically designed to be combined with other Lynx M10 products. It can monitor fuse status and receive alarms in case of blown fuse for up to 4 connected Lynx distributors, via VictronConnect or a GX device.

The M10 busbar of the Lynx Smart BMS 500 NG (M10) requires a tightening torque of 33 Nm. This specification is important to ensure a secure electrical connection.

The Lynx Smart BMS 500 NG (M10) can operate within a temperature range from -40 °C to +60 °C.

The Lynx Smart BMS 500 NG (M10) has an IP22 protection rating. This means it is protected against solid objects larger than 12.5 mm and against water droplets falling at an angle up to 15° from the vertical.

No, it is not strictly necessary. You can monitor and configure the BMS via Bluetooth using the VictronConnect application on your smartphone or tablet. However, a GX device like the Cerbo GX, combined with the VRM portal, provides more comprehensive local and remote monitoring, including cell voltage and temperature readings.

Yes, the programmable relay can be used to control an alternator via its external regulator (ignition wire). In "Alternator ATC" mode, the relay only activates when the ignition switch is closed. The alternator's "Alternator ATC" contact opens first, then opens the ignition switch with a 2-second delay, ensuring the alternator is disconnected before the battery is isolated.

The Lynx Smart BMS 500 NG (M10) is specifically designed for Victron Energy's next-generation (NG) lithium batteries using lithium-iron-phosphate (LiFePO4) technology.

It is compatible with battery systems configured for 12 V, 24 V, or 48 V. You can connect:

Up to 50 batteries of 12 V or 24 V. Up to 25 batteries of 48 V. The maximum energy storage capacity is 192 kWh for a 12 V system and up to 384 kWh for a 24 V or 48 V system. For increased capacity and redundancy, up to 5 Lynx Smart BMS NG units can be connected in parallel.

This BMS integrates seamlessly with the Lynx distribution system and Victron M10 products.

The Lynx Smart BMS 500 NG (M10) provides several key functions for the safety and monitoring of your battery bank:

Integrated safety contactor: A 500 A continuous (600 A peak for 5 minutes) contactor acts as a secondary safety mechanism and can serve as the system’s remotely controllable main switch.Precharge circuit: An integrated circuit prevents excessive inrush currents when connecting capacitive loads, such as inverters.Battery monitor: It provides real-time tracking of state of charge (SoC), voltage, current, and historical data.Battery protection: It safeguards against deep discharge and overcharging.Low-voltage pre-alarm: It issues a warning before the system shuts down due to low cell voltage.Programmable relay: This relay can be configured as an alarm relay or to control an alternator.AUX terminal: An embedded auxiliary power supply (1.1 A at system voltage) can power specific consumers, such as a GX device, after a BMS shutdown due to low cell voltage.Fuse monitoring: It allows monitoring of the fuse status of up to 4 connected Lynx distributors.Connectivity: Monitoring and configuration are performed via Bluetooth (VictronConnect app) or a connected GX device (Cerbo GX) and the VRM portal.
