Dual Battery Set-ups
I'm going to be adding a dual battery setup in my '67 Ford. Can any of you guys post up pics of your setups, and where is the best place to buy good quality battery cables in 6ft lengths or so? Around here its impossible to find.

It's best to run an isolator. Most isolators will charge both batteries at the same time and only pull power from the second battery when the engine isn't running. Some will let you swap which battery is the starting and which one is the AUX by flipping a switch.

Two batterys in mine, positive of the main battery to an isolator, then on to the positive of the secondary, Grounds to grounds. I bought #2 welding wire, and new connectors, works great and looks good. Moimted the second battery in the same spot as the main battery, but on the driver's side of the truck

You may have this already solved, but for mounting them you could go to a junkyard and get the batt tray of a diesel... or maybe just a stock one but flipped around would work too. but yall probably thought about that

I went an did some reading in Isolators, they don't give those things away. So a guy could just get by running dual batteries without one. I was planning on running dual batteries to run my off-road lights and a winch in the future.

If you wanted to go cheap, cable them together in parallel, and use a blade switch to disconnect one battery when you need to use the winch or stuff when the engine is off, that way you'd have a fresh battery to start the truck with. when your running the engine use them both. basicly its an isolator, but your doing it manually.
the problem running 2 batteries is that everytime I get out of the truck in the rain, someone just has to tell me. "your lights are on".
I know they are on, I just don't care. I'm pumping gas, it will be running in 2 minutes. even one battery would be fine
