Oh - and further to the 36v parallel / 72v series idea, I have been recently talking to folks

In a loud announcer voice "You are correct sir!" ding ding ding.

Personally I would lean towards 48v bank at this point, like you noted it's less batteries overall and less load per battery for the same "speed" and more potential top end power but not for as long as 2 strings of 36.

Not wanting to tear up your stuff does not make you chicken or cheap. I was just teasing. This is such a cool project. Thanks for letting us all follow along.

Brock - thanks for the confirmation.

Bill - but not wanting to spend the extra bucks for components that can handle more than 48v is.

MetroMPG: I am following your project and progress with great interest. Thanks for keeping us posted. You could consider your recovery and recycling of the dead batteries as purchasing some more green energy credits.

On the junction, you can use a acetylene torch to heat up the nut and the junction, so that you can get it loose. Pretty freaky thing when the brake lines are rusted enough their breaking open, but you can't get the stinkin fittings loose. Best of Luck.

Gary - yes, I should try the torch before monkeying with the splice idea. I do own one now, after all (my brother & I share one).

You're right: the situation with the nuts & rusted lines - it's irony defined.

Oooo, don't get dead or anything.

I like that giant motor. Surely someone is trying to build an electric small pickup truck and could make good use of it. Or something really cool, like a 240Z... :-)
