Saw this posted up on another forum, so I figuered Id shoot the news over this direction. Looks cool, and from what these guys are saying these Li-Ions will NOT explode or catch fire. Web site is not finalized but the pitch is definatly eye catching. http://www.a123racing.com/
They call thier battery tech, "Hypersonic". Heres the pitch.
"Hypersonic™ the ultimate in lithium ion performance
Safe, durable, high power batteries for R/C vehicles. Hypersonic™ is the highest power density battery pack available on the market, safely providing up to 30C continuous output and 60C burst rates.
