Best connect to parallel batteries?

If you've got two Group 27s with screw terminals and lug terminals (or whatever you call the typical auto clamp on terminals) and you're going to connect them in parallel, which terminals do folks usually use for this, the screw ons or the lugs? I haven't gotten the cables yet, so I can go with either.

The automotive terminals can carry more current than the studs, so I would connect the batteries in parallel with the automotive terminals, and whatever you have to charge them with. Needs for the vessel can come off the studs, depending on current demand.
Good Luck

Just as important is the wire gauge and how the cables are put together. I would favor a pre-made cables over ones that you might make yourself as there would be less chance for corrosion and power loss.

Thanks Dan and Kary. I will definitely be using premade cables sized generously. Scoping it out now so I get them right

Here's a link on how to make battery cables the right way if you wish to make them yourself. Making Your Own Battery Cables Photo Gallery by Compass Marine at pbase.com
If you decide to purchase them GenuineDealz.com - Marine Electrical, Boat Wire & Cable, Custom Battery Cables will do the crimps for $1 labor each plus parts. Their prices for cabling and lugs are excellent as well.

Preaching to the choir, mitiempo. You (or another sailnetter) pointed me to GenuineDealz in an earlier thread related to this project and I'm locked in
