Re: understand 12v electrical
Changing the AH capacity of the bank from the 232 'manufacture' capacity to 209 AH changed your state of charge by 10% because you dropped your capacity 10%.
Put it back to 232 AH, run a equalization process via your charger (overcharge them on purpose)... and above all else do some reading on how batteries work.
If I can learn it, so can you.
Lessons learned are opportunities earned.
