Not sure why some of you have so many problems with Hobby King. I have placed at least 20 orders with them over the past 2 years. I've purchased motors, ESC's, and numerous other parts from them and always got exactly what I expected or more. As for lipo packs, I've purchased 36 packs of Zippy, Turnigy, and Rhino and have yet to have an issue with any of them. I've had a few that came with cells that were out of balance, but after several cycles balanced perfectly. My oldest packs probably have 150 cycles on them and are, just now, starting to show diminished capacity. Of course, I balance with every charge, use a quality charger, don't over amp them, and don't discharge them past 70%...I've found, for the price, they can't be beat....As far as "CUSTOMER SERVICE"....Since I've never had an issue, I can't say how they do...

Now....To be honest, I have to say that on my 3300ma and 4000ma packs, I don't think I've ever approached discharge rates of 100 amps, even though they say 30C. I have, on several occasions, lit 60 amp ESC's on fire, though....LOL.
