The Lynx Smart BMS is a dedicated Battery Management System (BMS) for the Victron Lithium Battery Smart batteries. These batteries are Lithium Iron Phosphate (LiFePO4) batteries and are available in 12.8 V or 25.6 V in various capacities. They can be connected in series, parallel and series/parallel so that a battery bank can be built for system voltages of 12V, 24 V or 48 V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84 kWh in a 12 V and up to 102 kWh in a 24 V1) and 48 V1) system.
For more information on these batteries, visit the Victron Lithium Battery Smart product page. Out of the various available BMSes, the Lynx Smart BMS is the most feature rich and complete option and integrates seamlessly into the Lynx Distributor system. It is available in 500 A (M8) and 1000 A (M10) versions.
Its main features are:
- Built-in 500A contactor used as a fall-back safety mechanism and also suitable as a remote controllable main system switch. - Battery monitor, indicating state of charge percentage and more data. - Pre-alarm signal: provide a warning before the system shuts down due to -for example- a low cell. - Bluetooth for use with our VictronConnect App, for setup and monitoring. - Local and remote monitoring using a Victron GX device, for example the Cerbo GX. - The Lynx Smart BMS is part of the modular Lynx Distribution system.
Built-in 500 A or 1000 A contactor-The contactor acts as a secondary safety system to protect the battery in case the primary controls (ATC, ATD and/or DVCC) fail to disable loads and/or chargers when required and is also suitable as a remote controllable main system switch.
Pre-charge circuit-In addition to the contactor, a built-in pre-charge circuit prevents high inrush currents when connecting a capacitive load such as a MultiPlus/Quattro or other inverter, eliminating the need for external pre-charging.
Monitoring and control-Monitor and control the BMS via Bluetooth using the VictronConnect App or a GX device such as a Cerbo GX and the VRM Portal. A built-in battery monitor that operates in a similar fashion as the other Victron Energy battery monitors, provides data such as state of charge, voltage, current, historical data, status info and more in real time, and with Instant Readout even without the need to connect to the BMS, allowing diagnostic at a glance.
DVCC closed loop control as well as ATC/ATD contacts-Compatible Victron inverter/chargers and solar chargers are automatically controlled via a connected GX device and DVCC. The ATC/ATD contacts can be used to control other chargers and loads that have a remote on/off port.
Programmable relay- The 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). In Alternator ATC mode, the relay will only activate when the contactor is closed. Alternator ATC contact of the alternator opens first and then with a delay of 2 seconds the contactor. These 2 seconds ensure that the alternator is switched off before the battery is disconnected from the system.
AUX terminal- The advantage of the onboard auxiliary power supply (1.1 A @ system voltage) is to provide power to specific loads (i.e. a GX device) after the BMS has shut down the loads in the event of a low cell voltage event. If no charge voltage is detected within 5 minutes, the BMS including the AUX connection switches off.
VE.Can and NMEA 2000 data communication- VE.Can allows for easy connection (standard RJ45 network cable) and communication with a GX device. Since the CANbus protocol is based on NMEA 2000 (and J1939), it is easy to integrate into a marine network and feed your marine MFD with data (requires a VE.Can to NMEA 2000 micro-C male cable).
Lynx Distributor fuse monitoring- Read out fuse status and receive an alarm in case a fuse is blown. The Lynx Smart BMS monitors up to 4 connected Lynx Distributors and their fuses via VictronConnect or a GX device

What is a warranty? A warranty is a voluntary promise offered by the person or business who sold the product or service to you. Once you buy the product or service, the promise becomes a right that can be enforced under the ACL. Warranties are separate from your automatic consumer guarantees. The consumer guarantees which apply regardless of any warranties suppliers sell or give to you, apply for a reasonable time depending on the nature of the goods or services. This means consumer guarantees may continue to apply after the time period for the warranty has expired.
