Not sure where you got that info from but the data sheet that came with my new kokam 1200HC said that it can handle 8C average maximum current. That works out to be 9.6 amps continuous. And with the settup I have now I am running about 15 amps static with WOT so that unloads to 12-13 amps in the air. I am only running less than half throttle most of the time anyway. I need about half throttle to hover. It hasn't cut out on me yet. The motor does get a little hotter than normal but the kokams are in a normal range of warm.
I almost forgot, at the very top of the brochure that came with my battery pack it said that the 1200HC was a high discharge type. I'm not sure what the 1200HD reference is.
