I have four 6v golf cart batteries configured in a series/parallel circuit. They are not cross-tied. Is it even possible to monitor the midpoint like this? At some point I connected B2 from the shunt to the positive terminal that is in-between one of the series. I think I'm only monitoring the midpoint of one set of batteries, right?
Is there any way to do this across all four batteries without adding cables and cross-tying everything?
