Strange battery readings

[jagmanx]

I have an EVS 30/20 power management unit.
It services both EB and LB !
Also a 120watt solar with Mppt controller.
Before with 1 LB the LB lozenge as with the EB lozenge would show full by 10am
Now I have 2x Lb and the LB lozenge shows ok but not "full"
The left lozenge shows water % the right lozenge shows the 2 batteries on a rocker switch
I have a voltage meter which during the day and now 8pm shows 13.7 v ? In
Left image shows EB full. This shows lb bank ok but not full !
Any thoughts please ?
I had. A hab check done and a suggestion to monitor the charger !

Update !
Put a multimeter on one of the pair of LBs and it registered 13.5
Will get to the other one tomorrow as it is a bit of a challenge !
But that seems fine to me ?

Should hit 14.4 in mid sun but drop back after full charge to about 13.7, falling at night to 13.2/12.7 at lowest point before usage.

Yes it seems the lozenge reading is now inaccurate as it used to show 100% !
Will rely more on the voltmeter which is always on !
Now showing 13.7 ! We are on EHU...Will have to wait until we escape from our prison to check all is fine with no EHU.
Maybe i will unhook and put the fridge on gas tomorrow !

Unplugged ehu !
Voltmeter showing over 14v from solar !
Lozenge up to 80 % so all seems good !

This is better..The battery gauge meter/lozenge !
This now shows 100% for both the cranking battery AND the leisure batteries.
There is a rocker switch which allows me to monitor both.
As shown with my finger in post 1.
This would usually be the case previously after some morning solar input.
Happier now !

No wonder you are confused, that's an espresso coffee machine.
