"We’ve tested many different battery solutions over the last year, including Ener1 and several of its competitors," stated Richard Hatfield, founder of Lightning Motorcycles. "The Lightning data and test results showed us that Ener1’s lithium-ion batteries far out-perform those from competing companies, which is why we’ve switched to using their cells in our electric motorcycles. Lightning Motorcycles is committed to using what we believe to be the most powerful, safest, best-of-breed batteries on the market, which is why we’re also extremely pleased to be representing Ener1 as an official distributor."
Assuming HEV does not get delisted from NASDAQ for being under $1 for too long (not really sure how this works) maybe HEV is a good purchase? I read they took a big hit from Th!nk Global EV going out of business. I believe they had a stake in the company.
