Hi,
You can do it--but it is best to isolate the two banks from each other particularly for storage.
If there is only room for three batteries, once the six volts die move to three brand new 12 volt trolling batteries wired in a balanced manner.
Agreed. Consider using an A B switch. Put the two six volts on the A position. Keep the 12 in reserve on the B position.
Good luck and happy trails
I never thought about having a switch between banks. I am going to look into that a little more. AWESOME IDEA!
