you cannot mix aluminum and copper battery terminals...you are asking for all kinds of corrosion problems.

Bruce see if you can find us some 5/16 copper rod or threaded copper rod, I found it in china but need to buy a ship load that's one more than I need.

I found out the same thing, all bolts, rod where overseas. I did find some machine shops that specialize in fastners, but had big min orders.

So, we need some threaded solid copper, from somewhere.

Are we sure 5/16 is the biggest that will fit? Maybee 3/8 ?

I was just gonna run a #2 around the OBC and hook both the #2 and stock 6 gauge up, but I like the idea of only one cable.

My wifes uncle owns several cnc's up in PA, they do alot of railroad work, brass and such, I will call him and see if he has any solid rod.

No luck with uncle, they use mostly flat bar stock, he has never used round or square stock.

There is a place around the corner called Acme surplus, going by there in the morning, they have stuff there even the owners couldn't identify
if they have whats needed I will pick some up and let yall know.

If anyone is near Orlando, they should stop by Skycraft on Fairbanks and take a look around.

If I find it , I will get enough for a few of us.

Look what I found mcmaster carr this stuff is so clean it will generate volts

Ultra-Conductive Copper (Alloy 101)

Also known as oxygen-free high-conductivity (OFHC) or oxygen-free electronic (OFE) copper, this ultra-pure (99.99%) copper is good for high-temperature applications such as terminal lugs and wire connectors. It can be welded and brazed. Not heat treatable.

Rods – Unpolished (Mill) Finish

Hardness: Rockwell F84-F94, except 6" dia. rods have a hardness of Rockwell F42
Yield Strength: 40,000 to 50,000 psi
Temper: Hard (H04)

Meet ASTM B187. The 1" to 6" long rods also meet ASTM F68. Straightness tolerance is 1/2", except 1" to 6" lengths are not rated. Length tolerance is +1/16" for 1" to 6" lengths, ±1/8" for 1-ft. lengths, ±1/4" for 3-ft. lengths, and ±1/2" for 6-ft. lengths.
