opinions about batteries....

I don't think IR can be the whole story as the 5800s were definatly faster than the 5000s even with the same prop, I have dumped the 5800s in 3 minutes which is 116A 20C, that would be 64C for the little 35C rated hyperions and I doubt they are that underrated.

readings are taken during balance charging with the balance leads pluged in, the 5800s have been stripped with balance leads under an inch long, 10guage power leads about half an inch long soldered directly to the tabs, no PCB. I Used the same charger as above this time too, a Fusion Emperor L720B Pro

Pack IR is actually the only story as far as performance goes... chargers might not be the most accurate when it comes to calculating pack IR to begin with. The Turnigy pack is literally dumping out on you early, which would give a false calculation on the current draw you are using, what kind of temps are you getting? What is your LVC set to?

Also, what are these 5000's you mentioned?
