Well, first off I only cycle them to check capacity and/or see if they are still functional. I know it is not necessary to cycle Lipos for their own "benefit".

Secondly, that's the weird thing, most of them will cycle test fine at the low amperage, (say less than 2 amps) of the charger/cycler. But when you put them into use, and start drawing some real amperage in flying, like say 10 x "C" or 20 amps for example, they fall flat in a very short time. I know the math doesn't make sense, but I figured something was happening to them that caused them to not be able to deliver their normal amperage under the higher amp loading of actually flying them in place of just cycle testing with low amperage.

I cycle down to 3 volts per cell to answer that question.
