12v and 2 batteries

5 posts in this topic

How do you connect 2 batteries together and still have 12v not 24v?

Positive to positive and negative to negative will keep you at 12v.

The batteries must be in the same condition though. I.E. both same age and size. If one is better than the other it will draw from the good one to the worse one thus ruining the better one.

Running your batteries in parallel will double the run time if the two batteries are like for like. I used to have a perm on Mille Lacs, and ran 4 6v golf cart batteries. both sets in series, to get 12v, then ran those sets in parallel to keep 12v. They would last almost all winter running the lights.
