Brettmm92,

Try Lowes or Home Depot

They will have "building wire" in that size, consists of thick strands and will not be flexible enough for this use.

You NEED flexible wire which consists of many much smaller strands.

Better to go to an autoparts store.

You can find short battery cables with a molded battery terminal on one end like this..



Then you can use a REPAIR battery terminal on the other end like this..



and use one of the bolts on the terminal to connect your cable end to for a couple of Dollars.

or for more expensive terminals..



Or you can buy a short 12" cable with lugs like this..



and use the repair terminals to make the connection to the batteries.

You should be able to find these at most any autoparts stores like Autozone, Pepboys, NAPA and more..

Take these photos with you and show them what you need, some places like NAPA may even custom cut to length and put lug ends for you..

Ideally you want this interconnect to be as short as possible, so depending on how you need to place the batteries you can often get away with as short as 6"..

In a pinch building wire at Lowes of Home Depot could be used, but it is extremely stiff and that can make it difficult to work with and it can also place a lot of stress on the battery terminals which may lead to the case to terminal seal breakage which leads to acid creep up the terminals. That causes a lot of acid corrosion of the battery connections when that happens.
