1.1. The Lynx Smart BMS

Lynx Smart BMS 1. Introduction 1.1. The Lynx Smart BMS 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. This is the safest of the mainstream lithium battery types. 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. Up to four 12.8V batteries or two 25.6V batteries can be connected in series. A total of 20 batteries can be connected, resulting in energy storage of up to 84kWh in a 12V system or up to 102kWh in a 24V and 48V system.

The maximum energy storage capacity can be multiplied by paralleling multiple Lynx Smart BMSs, which also ensures redundancy should one battery bank fail. There are multiple BMS-es available for our Smart Lithium series of batteries, and the Lynx Smart BMS is the most feature rich and complete option. Its main features are: Built-in 500A or 1000A (for the M10 model) 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 a low cell voltage.

Bluetooth for use with our VictronConnect App , for setup, monitoring and diagnostic. Local and remote monitoring using a Victron GX device, for example, the Cerbo GX and our VRM portal . The Lynx Smart BMS integrates seamlessly into our Lynx Distributor system and is available as a 500A (with M10 busbar) or 1000A (with M10 busbar) version.

Lynx Smart BMS 2. Features 2.1. Battery Management System 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. It's main features are: Pre-alarm mode configurable via the programmable relay ATC/ATD ports to control chargers and loads DVCC closed loop control for compatible Victron inverter/charger and MPPTs via a connected GX device Discharge floor used to set the minimum SoC to determine how far the battery is allowed to be discharged.

(requires VictronConnect v5.70 or later) A configurable pre-alarm warns with a minimum delay of 30 seconds of an imminent shutdown of the loads as a result of an impending low cell voltage. By reacting quickly on the pre-alarm, for example by reducing the load or starting a generator to charge the batteries, the shutting down of the loads can be prevented. The ATC contact is opened to stop charging at high cell voltage or low temperature, while the ATD contact is opened to stop discharging at a low cell voltage. DVCC controls compatible devices via Lynx Smart BMS and a connected GX device.

Charging current and voltages are set automatically, thus Bulk, Absorption and Float algorithms are no longer used. Charging or discharging are stopped at low or high cell voltage or low temperature. 2.2. Contactor The built-in contactor serves two purposes: 1. It acts as a secondary safety system to protect the battery in case the primary controls (ATC and ATD contacts as well as DVCC) fail to disable the loads and/or chargers when required. 2. It can be used as a remote controlled main system on/off switch via the VictronConnect app, a GX device (only Standby and On), as well as using the Remote on/off terminals. 2.3.

Built-in pre-charge circuit The built-in pre-charge circuit pre-charges capacitive loads such as inverters or inverter/chargers before the contactor closes to prevent high inrush current. 2.4. Battery Monitor 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. 2.5. Programmable relay The Lynx Smart BMS has a programmable relay that can be used as an alarm relay (combined with the pre-alarm) or to shut down an alternator via its external regulator (ignition wire).

2.6. AUX terminal The Lynx Smart BMS is equipped with an auxiliary power supply. This supply outputs the same voltage as the system battery voltage and is rated at a maximum continuous current rating of 1.1A. The purpose of the auxiliary power supply is to keep certain systems powered, for example a GX device, after the BMS has turned off loads in case of a low cell voltage event. It is recommended that the system includes a GX device powered by the AUX port. This keeps the GX device supplied with power until the AUX port is finally switched off (max. 5 minutes after a low cell voltage event) to preserve energy for battery self-discharge. Page 2 Features
