Beyond that I think you get into (controlled) tests that could potentialy damage the cells.

I have done this on my lipo's and they all have come up short. Maxamps 4s6000mah 20c tests at 70 amps @ 12 volts which makes it 11.66c . Trinity Lipro 2s 4500mah 20c tests at 40amps @ 6 volts which makes it 8.88c. The trinity packs I tried to get the rated 20c (90 amps), 70 amps was max I could get and the voltage went down to 2
I only held it there for a few seconds. Basically you could dead short the Trinity packs and 70 amps would be all you would get. I don't have alot of faith in the manufactures numbers.
