The site is a mess... call and ask for Larry. Shawn Palmer swears these are the best lipos he has ever ran by a long shot. And they say they don't flame if punctured and tend to withstand more abuse of all kinds compared to other lipos. These are the cells that Orion and Peak use in those carbon fiber case packs. I have talked to Shawn and Larry at KokamAmerica a lot about these but I haven't got any yet because I already have a bunch of barely used maxamps cells and it's not race season here. I plan to try some in the summer.
I can't remember the sites I've seen the flightpowers for sale. I have read about them on rcgroups.com and other places. I just saw an ad for flightpowers in a hard case like the Orions the other day... if I see it or remember where I will post it.
Hope that is of some help... I'm kinda stressed right now... just wrecked my car tonight.... :(
