Lynx Smart BMS 500 (M8)

The Lynx Smart BMS 500 (M8) is a battery management system (BMS) designed for Victron Lithium Smart (LiFePO4) batteries. It integrates a positive and negative busbar, a BMS, a 500 A main contactor, and a battery monitor. Its function is to protect and manage the battery bank while providing detailed information on their status and simplifying the system architecture.

The Lynx Smart BMS 500 (M8) is specifically designed to be compatible with Victron’s Lithium Battery Smart range. These batteries are Lithium Iron Phosphate (LiFePO4) type and are available in 12.8 V or 25.6 V.

The Lynx Smart BMS 500 (M8) supports system voltages of 12 V, 24 V, and 48 V. Lithium Smart batteries can be connected in series, parallel, or series/parallel to form a battery bank suitable for these voltages.

The main contactor integrated into the Lynx Smart BMS 500 (M8) has a continuous rated current of 500 A.

The main contactor of the Lynx Smart BMS 500 (M8) can handle a peak current of 600 A for 5 minutes.

The integrated pre-charge circuit prevents high inrush currents when connecting capacitive loads, such as a MultiPlus/Quattro or another inverter. This eliminates the need for an external pre-charge and protects the equipment from damage.

You can monitor and control the Lynx Smart BMS 500 (M8) in two main ways:

Via Bluetooth, using the VictronConnect app on your smartphone or tablet. Via a GX device (such as a Cerbo GX), which also enables remote supervision via the VRM portal.

The integrated battery monitor provides real-time data such as state of charge (SoC), voltage, current, as well as historical data and system status information.

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

Yes, the Lynx Smart BMS 500 (M8) is compatible with NMEA 2000 marine networks. Its CAN bus protocol is based on NMEA 2000 (and J1939), enabling easy integration and data transmission to marine multifunction displays (MFD) via a VE.Can to NMEA 2000 micro-C male cable.

The dimensions of the Lynx Smart BMS 500 (M8) are 190 x 180 x 80 mm (height x width x depth). Its weight is 1.9 kg.

The Lynx Smart BMS 500 (M8) is designed to operate within a temperature range from -40 °C to +60 °C.

The Lynx Smart BMS 500 (M8) has an IP22 protection rating, meaning it is protected against solid objects larger than 12.5 mm and against water droplets falling at a 15-degree tilt.

Yes, the Lynx Smart BMS can monitor the status of fuses for up to 4 connected Lynx distributors. It can also trigger an alarm if a fuse blows, and this information is accessible via VictronConnect or a GX device.

The Lynx modules are designed to interconnect easily. They connect directly to each other to form a compact and integrated distribution system using common busbars.

Power consumption varies by mode:

OFF Mode: 0.3 mA for all system voltages.Standby Mode: ~0.6 W (~50 mA at 12 V).ON Mode: ~2.6 W (~217 mA at 12 V), depending on relay state.

The AUX terminal provides a continuous auxiliary power supply of 1.1 A at system voltage. It is protected by a resettable fuse and can power specific loads (such as a GX device) even after the BMS has cut off main loads in case of low cell voltage.

Yes, the Lynx Smart BMS 500 (M8) is covered by Victron Energy's standard manufacturer warranty. For specific details and warranty conditions, it is recommended to consult Victron Energy's official documentation or contact customer support.

To connect Lithium Smart batteries to the Lynx Smart BMS, specific BMS cables (BTV cables) are used. These are 3-pole circular male and female connectors with an M8 screw ring. Up to 20 batteries can be connected in the same system.

The Lynx Smart BMS 500 (M8) is an advanced battery management system (BMS), specifically designed for Victron Energy Lithium Smart batteries. It is the intelligent and secure core of your energy system, integrating several key features:

Battery management system (BMS): It protects lithium batteries against overvoltage, undervoltage, overcurrent, and extreme temperatures, ensuring their safety and extending their lifespan.Integrated main contactor: A continuous 500 A (600 A peak for 5 minutes) safety contactor is integrated. It acts as a secondary safety system and can also serve as the system's main switch, controllable remotely.Pre-charge circuit: This integrated circuit prevents high inrush currents that could damage inverters/chargers (such as MultiPlus/Quattro) when connecting to capacitive loads.Battery monitor (shunt): It provides accurate real-time data, such as state of charge (SOC), voltage, current, and historical data, similar to other Victron Energy battery monitors.Integration with the Lynx distribution system: The Lynx Smart BMS is an integral part of the Lynx distribution system, simplifying the architecture and connections of your installation.Lynx Distributor fuse monitoring: It can monitor the status of fuses on up to 4 connected Lynx Distributors and trigger an alarm in case of a blown fuse.Advanced communication:Bluetooth: Enables monitoring and configuration via the VictronConnect app on your smartphone or tablet.VE.Can: Facilitates communication with a GX device (e.g., a Cerbo GX) for comprehensive supervision and remote control via the VRM portal.NMEA 2000: Provides easy integration into marine networks, allowing data display on compatible multifunction displays (MFD).Programmable relay: This relay can be configured to function as an alarm relay or to control an alternator via its external regulator.AUX terminal: Provides auxiliary power (1.1 A at system voltage) to specific loads (such as a GX device) even if the BMS has disconnected main loads due to low cell voltage.Parallel redundancy: Allows up to 5 Lynx Smart BMS units to be connected in parallel, each with its own battery bank, to create a redundant and secure battery system.
