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 detecting state of charge and preventing deep discharge and overcharging. It also includes a safety contactor and a 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 various 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 12 V or 24 V batteries, or up to 25 48 V batteries to a single Lynx Smart BMS 500 NG (M10).

Yes, the parallel redundancy function allows multiple Lynx Smart BMS NG units to be integrated 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 failure of primary controls (ATC, ATD and/or DVCC). It can also be used as the system’s main switch, remotely controllable.

Yes, the Lynx Smart BMS 500 NG (M10) features 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 is accessible 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 micro-C male VE.Can to NMEA 2000 cable.

Victron-compatible chargers/converters and solar chargers are automatically controlled via a GX device and DVCC. Additionally, ATC (Allow-to-Charge) and ATD (Allow-to-Discharge) contacts can be used to control other chargers and consumers that have a remote on/off ignition port.

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

The AUX port provides an embedded auxiliary power supply (1.1 A at system voltage). It is useful for powering specific consumers, such as a GX device, after the BMS has cut power to 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, specifically designed to be combined with other Lynx M10 products. It can monitor fuse status and receive alarms for blown fuses for up to 4 connected Lynx distributors, via VictronConnect or a GX device.

The M10 busbar on the Lynx Smart BMS 500 NG (M10) requires a tightening torque of 33 Nm. This specification is critical 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 rating. This means it is protected against solid objects larger than 12.5 mm and against dripping water at angles up to 15° from vertical.

No, it is not strictly necessary. You can monitor and configure the BMS via Bluetooth using the VictronConnect app on your smartphone or tablet. However, a GX device such as 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 contactor is closed. The alternator’s "Alternator ATC" contact opens first, then opens the contactor with a 2-second delay, ensuring the alternator is cut before the battery is disconnected.

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 at 12 V, 24 V, or 48 V. You can connect:

Up to 50 batteries at 12 V or 24 V. Up to 25 batteries at 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.
