Ive tested a wide range of 2.2AH packs of various C rates. Some packs were tested up to up to 20-30C and they dont fair well meaning the voltage sucked. The only packs that didnt suck were the A spec NanoTech followed by the Turnigy 60C Heavy Duty followed by the lower level nano techs. In my verdict Turnigy 20C was still the best bang for the buck and for some reason always over delivered when ran at 1/4 of the stated C rating. The A - Spec held an overall highest voltage and delivered exactly what it was supposed to it didnt matter if it was at 30C or 1C. What I saw with these multistar packs is at 5A or 0.5C or 25A or 2.5C there was negligible change in capacity. Although pack heating under a 25A sustained discharge was concerning which could lead to premature gassing and puffing if you pushed them hard. Neptronix and I agree that for most HK packs we need to derated them to a 1/4 of their stated C rating for continuous discharge and leave the peak ratings for just that Peak.
