Like this? I didn't like those copper straps that come with TS cells either.

I used stainless steel button head allen bolts. I covered my allen wrench with heat shrink so only about 4mm of the tip was exposed. Even if dropped on my battery pack it couldn't short anything out.

The price in AUD is almost the same as USD. The Australian dollar is typically worth between 90 and 98 cents US. It is shipping that will hurt, it will cost about $80 to ship 50 interconnects. They are heavy! Still, the total is less than $5 each when you buy enough to do a pack.

My batteries where made in February of this year and the terminals are copper on the negative and aluminum on positive side. The available thread depth is different on the terminals, measure both sides so the bolts don't bottom out before tightening. I think it's the aluminum terminal that is slightly less deep.

ElectriCar -- the pos terminals are copper and the neg are aluminum.

Other way around, the negative terminals are copper and the positive terminals are aluminum. (the red metal is NOT positive )
