Yes it seems like they are simply wired in parallel. I can just pull the ground cable off of either one and everything works the same.The spec batteries are 660CCA each, and a 160 amp alternator. It does crank over fast with 2 good batteries. Of course it starts with just a bump of the key in less than a second, but my 1950 216 only takes like 2 seconds if I get it set up right with a couple pumps of the throttle, a little choke, and throttle cable adjustment. It starts faster than my Camry when I get it right.
