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.
On first power up and after a "Reset to defaults" (via VictronConnect app), the Lynx Smart BMS automatically determines and
sets these settings:
• System voltage, 12, 24 or 48V, by measuring the battery voltage.
• Pre-alarm support in the batteries.
The settings can also be reviewed and changed manually.
6.2. Update firmware
On a new install, it is recommended to update the firmware of the Lynx Smart BMS. If there is a newer firmware version available,
the VictronConnect app will notify you of this as soon as a connection with the Lynx Smart BMS is made.
To check if the firmware is up to date or to manually update firmware, connect to the Lynx Smart BMS using the VictronConnect
app and follow below steps:
1. Navigate to the product settings by clicking the cogwheel icon in the top right hand corner of the product status screen.
2. Click on the 3 dots icon in the top right hand corner of the settings screen.
3. Select "Product info" from the pop-up menu.
4. The firmware version will be displayed. It is mentioned whether this is the latest firmware version. If a newer firmware version
is available, an "UPDATE" button will appear.
5. To update the firmware, press the "UPDATE" button.
The firmware update is even easier via the
feature (requires a GX device in the system and
internet connection).
In case of a new installation, it is also recommended to check and update the firmware of each connected lithium battery. This is
done via Bluetooth using the VictronConnect app in a similar manner to that outlined above.
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).
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.
section 3.1 to learn how to determine battery capacity.
If the battery capacity input is incorrect, the SoC will also be incorrectly calculated. Make sure the battery
capacity calculation is correct.
Set the Number of batteries in parallel :
• Enter the number of paralleled batteries in the system.
The wrong number of parallel batteries will lead to a miscalculation of the balancing algorithm. Make sure this
value is entered correctly.
Check the Pre-alarm mode setting:
