bitschee Report post Posted August 21, 2014 I remember seeing an article on how to connect 3 12v batteries. Can you tell me which back issue it was in or provide me the information. Share this post Link to post Share on other sites
wolfe10 Report post Posted August 21, 2014 bitschee, I do not recall the issue, but with 3 12 VDC batteries to make one bank of 12 VDC, connect all the positives together and all the negatives together. Connect the positive of battery #1 to house positive and negative of battery #3 to house ground/neutral. Yes, there are very slight improvements for more "balanced" cable connections, but this one is simple and will give you 95% of the more complex arrangements.
