Just about to wire in 4 6v golf cart batteries on my boat. I was going to connect each pair in series then in parallel. But as I was flipping through the Calder manual, I found this in his book at around page 22.
In a series/parallel setup. It is an excellent practice to cross-connect the positives and negatives on the individual 6v batteries, or 2v cells, (as shown in a picture). This minimizes the differences in the way the batteries work and perform.
I don't have a scanner where I am but I took a picture from another post and did a little msn paint on it to represent the diagram in the Calder book. The blue lines show the cross-connect that are in addition to the normal setup.
Do you connect your batteries this way? Did I read something wrong?
