Naio,
According to your post you are doing everything correctly. The battery you reported on should be put into service and with those thick plates should give you long, trouble-free service.
A lot of this chatter deals with nuances. I should make myself clearer as to what is interesting versus what is important.
Once Delta T voltage slump is established, compensated voltage should be noted then can be dialed-into the initial power supply setting when voltage is pre-set meaning before the cables are connected to the battery.
For instance, my power supplies. Lambda, Meanwell, and Megawatt all slump when connected to battery. This means, the converter will show say 14.70 volts with cables disconnected, but then settle on 14.51 when connected. Voltage does not rise to 14.52
What to do?
Then, do not pre-set the disconnected voltage at 14.70. It will be .19 volts too low.
Twist the adjustment pot to 14.70 + .19 volt = 14.89
Disconnected pre-set voltage thusly will be set at 14.89
Monitor finish voltage to be sure this is a correct assumption and tweak accordingly.
Different types of batteries will have different amounts of Delta T voltage slump. Types of batteries, not size or state of charge.
Once the Delta T compensation is set, it is set.
Note it. Write it down on a strip of masking tape.
Example: 14.70 set to 14.89
13.30 set to 13.39
