Also measure manually on the battery terminals with a meter if what is reported is correct.

On your GX device, make sure BSL (not automatic) is the selected battery monitor.

I also use a Quattro and BSL but with "automatic" selected. That always chooses BSL. Everything works normally.

I don't know how to disable the Quattro/VE.bus SOC.

The Quattro's SOC isn't particularly suited to this type of battery. You should really disable it, so it can have no say in any downstream logic.

What stands out in your pics (1 min apart) is the reported difference between the 52.11V of the BSL and 58.62V of the Quattro. What's happening there?

VEConfigure will work for all vintages of Quattro. Or try Victron Connect. These apps and their manuals all available from the Victron website.
