Maybe their Coulombic efficiency is not very high? I am still wondering if this efficiency is converted into heat, or if I am off base with this..?

I have seen one video on youtube where they test a flightmax 20/30C 2200mah pack and the voltage drops to 3.05v/cell @ 26C, which I guess isn't too bad, and might actually be on target for a 20C rating... but I would like to see the same kind of test for the 30C packs. Cuz don't get me wrong, I am very interested in these packs, I just have not seen any data showing they deliver as advertised.

Where as I did a bit of research on the Hyperion G3 35C packs I bought, and on RCGroups, and helifreak forums they did some good tests and they really do deliver amazing power, and just a touch off the 'ultimate pack' Thunderpower 40C batteries, but for almost 1/2 the cost of the TP.

Like you said Sike, these G3's are delivering the power right up until the end, much like A123's in fact. From the few tests I did of my own, I found they would deliver around 3.35v/cell at 35C discharge, maybe higher. The one temp reading I ever took was at the track, someone else's gun (lost mine), the temps were only ever 5F above ambient temps... that's impressive.

I suspect Flightpower is using the same cells in their EON X30 packs, as they state VERY similar benefits for their 'new' packs over their old ones. Neu I think might be using these cells as well, along with CTech batteries.
