BMV-700 GEL battery settings

I need help to set the parameters correct for my two Exide GEL batteries In my BMV-700.

They are charged with a MPPT solar charger, and also via my RVs internal charger.

2x85Ah

This is the settings that I use today, but SOC 100% to fast...

Is there anything not correct?

When a BMV is first installed it says 100% SOC out of the box to what ever it is connected to.

So if your battery was not at 100% when you connected it it will be out of sync. After a cycle or two it may re sync.

Do you have the datasheet for the batteries?

The settings that do affect the drift will be the charge detection time - maybe increase it and the tail current. Have you watched this video

Not knowing more about your particular batteries there is no way to know specific settings to do with float Voltage
