You have some sort of DIY shunt/cable connection on the negative post of your bank. What I'd suggest is to remove the cables and remove the shunt holder from the battery terminal and see how much resistance is through that connection. With two 4 AWG in 5' of run, you shouldn't see hardly any voltage drop.
Another thing you might try is to push some decent voltage through the single, lower 6V battery. Goose it hard and see if it responds.
Yeah, that is two pieces of flattened 1/2" copper pipe I needed to move and lower the shunt so it would clear the step the batteries are under. If you mean move the shunt overall, I don't think that's the issue, been good with it before the batteries. If not, you're right, the copper is the only thing new other than the batteries. I can try that tomorrow a beers in already...
Gotcha. I was thinking to test that connection combination, only, not advocating to scrap your design.
