12V Meter Curiosity......
Curious.....under charge the digital meter reads 100%.... 13.6V. At rest, fully charged....84%.....12.13V And the trailer "gauge" shows 100% What do you think?

When this gauge shows 100% it is with 13.7 Volts.
At 84% it is when the batteries are at 12.6.
I am going to keep an eye on the meter and create a table of sorts so that I know when the batteries hit 12V.
I also have another volt meter that I might install....it shows the actual volts.
If I had to keep watching that meter and be continually puzzled/PO'd, it would be replaced with a voltage meter that read in V, not percent.
I have two big, switched, Simpson analog meters that I can tell at a glance from 10' that voltages are correct.
Since I installed a Victron battery minder with AH meter, I mostly use that but it only measures the 12V system. I'm starting to understand that TT electrical systems are complicated, even if you build them yourself.
Just wait until you start considering solar, it gets another whole level of considerations beyond voltage measurement. The good news is that you have two excellent batteries to start with. Those Crown's will serve you well.
