You haven't been clear on whether your battery behavior is with or without loads being applied. This will be meaningful.
Sorry Marc, yes that is while supplying about 8 to 12 amp
I keep looking at the voltmeters to use them like a fuel
gauge but I am starting to understand that the voltage goes up and down depending how big the load is
I saw earlier the voltage drops by .2 volt when a fridge cuts in
I still feel that my battery capacity should be higher
My plan is to disconnect one battery (240ah) for a day or two and then swap to the other battery and see if they behave in the same way, maybe one of them is not working right
