I have two of the best Car batterys installed. both toghter no switch. Never have a problem.

Now if you must have a switch then the way you want to go is fine.

But your battery selection is wrong IMO, You are running a starting battery and a deep cycle battery which charge differently

Deep cycle is made to charge and drain charge slow and long.

Starting batterys are made to never totaly discharge and charge anytime with the motor.

Everyone has a different way of doing it, I say use two smae batterys so they charge and discharge in the same manner, and you should be fine using thwe few things that you use.

If running a live well or something I would use a 3rd deepcycle alone and charge when I got home.

Do a search this has been talked about a lot latley!
