Lynx Smart BMS 1. Introduction 1.1. The Lynx Smart BMS The Lynx Smart BMS is a dedicated Battery Management System for Victron Lithium Smart Batteries. 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: •...
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.
Lynx Smart BMS 3. Communication and interfacing The Lynx Smart BMS communicates with other devices and services via a variety of interfaces. The following list provides an overview of the most important interfaces: • Bluetooth: to change settings and monitor the Lynx Smart BMS via our VictronConnect App.
Lynx Smart BMS 4. System Design considerations and examples 4.1. Integration into the Lynx Distributor System The Lynx Smart BMS integrates seamlessly with the Lynx Distributor system, which is not mandatory for operation, but highly recommended due to its ease of installation. It is important to note that the battery must always be connected to the left side of the Lynx Smart BMS (in normal position), while all loads and chargers are connected to the right side.
Lynx Smart BMS 4.2. System sizing 4.2.1. Current rating Lynx Smart BMS The main safety contactor of the Lynx Smart BMS has a continuous current rating of 500A and a peak current rating of 600A for a duration of 5 minutes. Even if the Lynx Smart BMS has an overcurrent protection, make sure that the current rating is not exceeded.
Lynx Smart BMS 5. Installation 5.1. Safety Precautions 5.1.1. Safety Warnings Lynx Distribution System • Installation must strictly follow the national safety regulations in compliance with the enclosure, installation, creepage, clearance, casualty, markings and segregation requirements of the end-use application. •...
Lynx Smart BMS 5.2.2. Mounting and interconnecting Lynx modules This paragraph explains how to attach several Lynx modules to each other and how to mount the Lynx assembly into its final location. These are the points to take into consideration when interconnecting and mounting Lynx modules: •...
Lynx Smart BMS 5.3.2. Connect RJ10 cable(s) These instructions only apply, if the system contains Lynx Distributor(s). There are two RJ10 connectors in each Lynx module, one on the left and one on the right. See below drawing. RJ10 connector RJ10 connector RJ10 connector RJ10 connector...
Lynx Smart BMS Lynx Smart BMS battery BMS cable connection examples 5.3.4. Connect the Multi connector The multi connector is the green connector on the bottom of the Lynx Smart BMS. The connector has 11 pins, numbered from left to right starting with pin 1 and ending with pin 11. See the Appendix for a table with pin-out and description [35].
Lynx Smart BMS For the system to operate correctly, it is essential that all loads and chargers are able to be controlled by either DVCC or the ATC and ATD signals. Ideally wire the ATC and ATD signals to a devices remote on/off connector, or, if that is not available, a Smart BatteryProtect Cyrix-Li...
Lynx Smart BMS 5.3.8. Connect the GX device Connect the Lynx Smart BMS VE.Can port to the GX device VE.Can port using a RJ45 cable. Multiple VE.Can devices can be daisy chained, but make sure that the first and the last VE.Can device both have a VE.Can RJ45 terminator installed.
Lynx Smart BMS 5.4.3. Lynx Smart BMS only For a very slim line system, the Lynx Smart BMS can be used just by itself. This is usefull if the system contains a single lithium battery or a single series string of lithium batteries together with a simple DC system. Please also note that no GX device is used.
Lynx Smart BMS 6. Configuration and settings 6.1. Power up for the first time The Lynx Smart BMS will power up when a battery is connected and the wire loop is placed in between pin 10 and 11 of the multi connector or the Remote on/off switch is switched on.
Page 18
Lynx Smart BMS This setting is automatically configured upon initial power-up and after a "Reset to defaults". It is enabled by default. • enabled: recommended setting. A visual or audible device linked to the programmable relay is activated in case of a pre-alarm. •...
Lynx Smart BMS The discharge floor prevents full discharge and should be chosen so that there is enough energy to keep the Lynx Smart BMS powered for 24 hours to provide sufficient time to recharge the battery. If the battery is not recharged after the discharge floor has been reached, the battery will continue to be discharged through self consumption until a low cell voltage event occurs, at which point the Lynx Smart BMS will go into OFF mode with a delay of 2 hours to prevent deep discharge.

Lynx Smart BMS 7. Commissioning and Operation of the Lynx Smart BMS 7.1. Commissioning the Lynx Smart BMS Commissioning sequence: Check polarity of all battery cables. Check cross sectional area of all battery cables. Check that each battery has the most up to date firmware. Check that if batteries have been connected in series, that each battery has been fully pre-charged (refer to battery manual).

Lynx Smart BMS 7.3. BMS operating modes The BMS in the Lynx Smart BMS communicates with the batteries and will safeguard them against low or high cell voltage as well as low or high temperatures. Such events are reported by the battery to the Lynx Smart BMS to take necessary action by turning off loads and/or inverter/chargers and chargers and either turning the Lynx Smart BMS off or on again, fully automatically or manually.
Lynx Smart BMS Mode Soft switch VictronConnect app Soft switch GX device Hard wired Remote on/off switch * Only possible from Standby mode How to manually switch device modes 7.4. Lynx Smart BMS trigger This section describes the behavior of the Lynx Smart BMS in case the pre-alarm threshold is reached or either a low or high cell voltage or low temperature event is triggered.
Lynx Smart BMS 7.7. VictronConnect-Remote (VC-R) support* VictronConnect-Remote functionality enables the Lynx Smart BMS to be accessed remotely through a GX product, via the VRM portal. This powerful feature allows full product configuration (except Bluetooth) and monitoring from practically anywhere in the world using the VictronConnect app.
Should this fail to resolve the issue, contact the point of purchase for technical support. If the point of purchase is unknown, refer to the Victron Energy Support webpage. 8.1. How to recover from OFF mode when no charge voltage was detected This chapter explains how to turn on the BMS (thereby activating the system again) after the BMS has switched to OFF mode when no charge voltage has been detected for 2 hours after a low cell voltage event.
Lynx Smart BMS System in Standby mode Switch the system to ON mode using the soft switch in the VictronConnect app or a connected GX device. Battery voltage issues The Lynx Smart BMS, on first install, will auto detect the battery voltage and set to either 12V, 24V or 48V. Each set voltage has a specific battery voltage range (threshold).
Lynx Smart BMS Check ambient temperature and check if the two built-in fans are running. Reduce the ambient temperature. Settings invalid Settings data is corrupt. Reset to factory defaults. 8.4. BMS issues 8.4.1. The BMS frequently disables the battery charger A well-balanced battery does not disable the charger, even when the batteries are fully charged.
Lynx Smart BMS Testing a Lynx Smart BMS by connecting a single BMS extension cable to both BMS cable connections Multiple batteries and BMS check: • Bypass one of the batteries by disconnecting both its BMS cables. • Connect the BMS cables of the neighbouring batteries (or battery and BMS) to each other, effectively bypassing the battery. •...
Lynx Smart BMS 8.4.7. ATC/ATD is missing Error #36 (ATC/ATD error) occurs when discharge current > 1.5A while ATD is disabled or when charge current > 1A while ATC is disabled. This can be caused by loads or chargers that are not controlled by ATC/ATD. Make sure all loads and chargers are controlled by ATC/ATD (if not controlled by DVCC).
Lynx Smart BMS 8.6. VictronConnect issues Interrupted firmware update This is recoverable. Just try to update the firmware again. 8.7. GX device issues This chapter only describes the most common issues. If this chapter does not solve your issue, consult the manual of the GX device.
