Description
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, 24V or 48V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of
84 kWh in a 12V and up to 102 kWh in a 24V and 48V 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.
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
