This TEK4 battery has 6Wh rated capacity ( usable is probably 5 Wh if you take good care of it ) , which means your EV pack needs about 2500 of these cells, at $12 each that comes to $30,000. So to answer your question, yes, you can do it, but there are much more cost effective ways of building EV pack of Lithium batteries. You can browse thru Batteries forum section here to get some ideas of what people are using in their EVs.

Hope this helps.
Wow! That is amazing. I will head over to the battery section. Thanks guys!
