    I want to run two batteries on my rig. I thought it might be a good idea to run one deep cycle along with my starting battery. Do I need to run an isolater to do this or can I just hook them up in parallel and call it good?

    Paralleling different battery types can lead to over/under-charging problems.

    I would use a marine battery switch, or continuous-duty solenoids.

    Isolator would work too, but doesn't give you the choices.

    I'm not making a recommandation, but a sampling of what's available

    Battery Mates and ACR's are the best tech for dual battery charging... Superior to any isolator system..

    But I agree with the others, if your gonna run a starting and deep, you should have them be selectable in one way or another...
