I selected PowerSonic (local company)PG-12V140FR , 144 Amp Hour batteries. I hope they work out.
When they run out I'll see where the price of Valence, A123, Altairnano, ThunderSky batteries are, and see what I can do.

the bolt in terms like to strip out and they are super hard to keep tight PG-12V140FR

What makes them strip out? What about using belleville washers as recommended on the EVDL?

Chris Jones has a good comparison table:

Hi Andy,
Do you have any references?
Are there any vehicles on the road we can check out using your batteries?

Thanks,
Manny

Also there's a parts vendor section here:

Looks like you answered your own question.

 

[Mannyman]

Not anytime soon. Hopefully a battery maker licenses their tech.
If you email them the response isn't as enthusiastic as you'd might hope.

My EV club asked if they wanted to be a part of an EV technology event and amateur drag race and the response was as follows:

Thanks for your inquiry. While we’d love to compete in this, we’re working on a couple of batteries that are optimized for applications different than EV. I’d love to know how it turns out, so please let me know when the event occurs so I can read the news.
