Li-Ion Power Tool cells work great for RC!

Metalman, I think you've got to realise that these A123 cells are not aimed at the rc market, they're aimed at big heavy powertools are other such applications. For powertools, 100C burst discharge is quite neccessary and 20C charge is also pretty handy! I don't think these cell's are designed to be the next ultra-lightweight, energy dense lithium cell -they're built to be heavy duty, and going by some of the info on that site I would say they do a pretty good job.
