The Lynx Smart BMS is a dedicated Battery Management System for Victron Lithium Battery Smart batteries available with a
nominal voltage of 12.8V or 25.6V in various capacities

The BMS is used to monitor, control and protect your Victron Lithium Batteries Smart. It detects the state of charge and protects
against deep discharge and overcharging

The Lynx Smart BMS battery monitor operates in a similar fashion as the other Victron Energy battery monitors. It contains a
shunt and battery monitor electronics. Readout of the battery monitor data is via Bluetooth using the VictronConnect App or a GX
device and the VRM portal

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 CAN-bus 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.

Parallel redundant Lynx Smart BMS
The new parallel redundancy feature for the Lynx Smart BMS and Lynx Smart BMS NG series allows multiple Lynx BMSes in one installation. Each has its own battery bank, and together they form a single redundant battery system. Up to 5 BMS's can be paralleled.
