David will pipe in with the technical, but right off the top of my head, if those are UA12200 12v batteries, you want positive to positive, negative to negative. The way you’ve described it, you have a 36v 22 amp battery.

"There is no god and that’s the simple truth. If every trace of any single religion died out and nothing were passed on, it would never be created exactly that way again. There might be some other nonsense in its place, but not that exact nonsense. If all of science were wiped out, it would still be true and someone would find a way to figure it all out again." — Penn Jillette
