Victron Energy Lynx Smart BMS 500A (M8)

The Lynx Smart BMS is a dedicated Battery Management System for Victron Lithium Smart Batteries. There are multiple BMS units available for Victrons Smart Lithium series of batteries, and the Lynx Smart is the most feature rich and complete option. It is available in two versions: 500A (with M8 busbar connections) and 1000A (with M10 busbar connections).

Key Features

• Built-in 500A or 1000A contactor used as a fallback 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 the VictronConnect App, for setup and monitoring.
• Local and remote monitoring using a Victron GX device, for example the Cerbo GX or Ekrano GX

The Lynx Smart BMS is part of the modular Lynx Distribution system.

Description 

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-es can be paralleled.
