I'd like to move my 2 Golf Cart 6V Lead Acid batteries (that are only 2 years old) from high in the boat to some place lower inside the cabin. Not ready for a LFP conversion since these batteries are still very good. Moving the batteries a couple advantages, chiefly a shorter run from the batteries to the electrical distribution panel, less weight up high, and move my batteries from the same compartment as my CNG

Has anyone done this and what considerations should be taken into account. (like outgassing, etc. For Hunter Legend 40.5 owners, where would be a good spot? The height of the GC batteries might be a problem and I'll be searching around for a good spot. I think my battery case is 14 inches tall. At some point I'll be doing a LFP conversion but not at this moment.

All thoughts and cautions, considerations, etc are appreciated.

The general thoughts about battery location are low and central, as close as feasible to the charging and distribution panel.

The complications are based on your individual boat design.

Consider just moving the CNG tank to the other side. Even if you put the batteries inside, the height difference between the aft locker floor and that in the salon isn’t much.
