Well...don't think top balance was the problem. I just got done topping up the entire bank and it still has the same problem.
I suspect it is a connection issue but won't be able to take everything apart until next week. I did some quick voltage readings and noticed that the voltage drop from the battery bank 1 positive terminal to the disconnect switch is (apparently) double that of battery bank 2 (they are roughly the same length). It's a tight fit, so I suppose it's possible I took too sharp of a turn with the cable? I suppose there's one way to find out.
I'll report back after I've ripped it apart and redone the connections...
