I don't want to compare apples with oranges, but the cells you'll have in connecticut are of a complete different kind. Especially cycle life at 30C is a bit disappointing. Also 6Ah isn't very impressive.
I like the 18.5Ah cell from FreeGo, because it would fit in a triangle better than a ping or headway battery.

PS: If I would want to build a high performance pack, I would use the Kokam 40Ah high power cell, which can deliver 400A cont./ 800A peak and cost only 100$ each ( in large quantities )
In fact, for my pocket bike I've chosen the high energy twin with 53Ah. Still way more power than I'd need...
The Dow Kokam's are much more expensive than $100 each. And if you were the compare prices/amps Haiyin wins the race.

I'm working for http://www.ececars.nl/modellen.
We have built EVs with Kokam for more than 3 years. I know what I'm talking about. Maybe you have to build up a reputation first to get good prices?!
