No guarantee the cells are perfect, but for the price it's worth the risk to some people.
Jack Rikard on evtv.me has done lots of testing with the "grey market" A123 Amp20's he has several rather long videos on testing these cells. He says they are good for 375 amps (23C) and he is selling them http://evtvshop.projectooc.com/products.php?cat=10
I was contemplating using these for my high current eKart build, but I needed a little more so I will be going with the Haiyin 6ah 3.7v calls which claim 50C ( voltage drops to 3.3v) constant draw. http://www.ecedra.com/thebatteryshop.html
These are what Lithuimmanics Drag racer runs \, but you have to be comfortable making you own pack. Make sure when you are taking voltage drop into account when calculating your max Kw rating. There are TONS of threads about this so I will not go into it here.
