Lynx Smart BMS 6.2. Update firmware A firmware update of the Lynx Smart BMS can be performed in two different ways: Via the VictronConnect app Via the VRM: Remote Firmware Update feature (requires an internet connected GX device) Notes on firmware updating in general Newer is not always better Don't break it if it works Be sure to read the changelog before starting the update process. The changelog can be downloaded from Victron Professional . Therefore: use this feature with care. Our main advice is not to update a running system unless there are problems with it or before the first startup.
Notes on updating the Lynx Smart BMS firmware A firmware update will not result in a temporary system shutdown. During the update, the Lynx Smart BMS keeps all contacts and the contactor in the same state as when starting the update. If the update fails, ATD/ATC and contactor open after 120 seconds, for safety reasons. This also gives time to try updating again. Updating the firmware always starts a new full charging cycle despite the SoC threshold setting, which means that the charge voltage limit (CVL) is automatically adjusted from 13.5V to 14.2V (for a 12V system). In case of a new installation, it is also recommended to check and update the firmware of each connected lithium battery.
Updating firmware via VictronConnect Please note the following before performing a firmware update via VictronConnect: 1. For detailed instructions on how to update the firmware, see the firmware update chapter in the VictronConnect manual. 2. If there is a newer firmware version available, the VictronConnect app (make sure the VictronConnect app is the latest version) will notify you of this as soon as a connection with the Lynx Smart BMS is made. Updating firmware via VRM: Remote firmware update Features: Remotely update internet-connected products straight from the VRM Portal No need to install any software Works from laptop, tablet & phone No need to find the right firmware file:
the system has all, and will clearly indicate that a newer version is available. See the VRM: Remote firmware update manual for detailed instructions. 6.3. Lynx Smart BMS settings Once powered up, use the VictronConnect app to configure the BMS settings. Check the Battery voltage setting (12, 24 or 48V): This will have been detected automatically, double check it. Set the Battery capacity setting: Enter the total battery bank capacity of the connected battery. Caution, for batteries connected in series, do not add the capacity of each battery to determine the total capacity of the bank. Check out our book Wiring Unlimited section 3.1 to learn how to determine battery capacity.
