[QUOTE=MrBlack]Would you care to explain this amazing technique that nobody else has managed to find including those that make the cells themselves?

If it involves temperatures this is not a sound solution as the advantage are marginal if any and inconsistant at best.

You got it. Temperature. Let me put your pack in a cooler for a while, and I'll heat mine up. HUGE difference in performance. It's easy to heat up NiMh because of the constant current peak charge method. Can't do it as easily with the lipo constant voltage charge. Everybody is going to have a heating pad of some sort with lipos go get them up to temp prior to racing. Do you really think that this isn't going to happen? Go run a pack that's at 50F, then heat one up to 100F and see for yourself. Marginal and inconsistent, not hardly. Very real.

Not that it matters, but I used to work at a Military/Aerospace lithium primary battery manufacturer in R&D. Was 10 years ago now, but I've been around lots of batteries.
