Lynx low voltage alarm won’t clear — but only in VRM

Hi all.

My system:
• (2) Smart Lithium 200 Ah
• Lynx Smart BMS
• MultiPlus II 12/2000/80
• Cerbo GX

I recently had an over discharge event and brought everything back per the battery manual instructions. In the process, I updated the firmware on all the devices and switched on DVCC to let the batteries/BMS control charging.

Since I connected everything up, the Lynx has been pushing a low voltage alarm to the GX which is showing up in VRM. However, both of the batteries are fully charged. No charging cycles or rebooting of the charger / GX has cleared the error.

No error shows up in VictronConnect.

The other strange bit is that the error shows on the main VRM screen but not on the GX — in fact if you navigate to the Lynx device in the GX and go to the Alarms screen, both “Low SOC” and “Low cell voltage” line items read “Ok”.

Any ideas for clearing the alarm would be much appreciated.
