thanks for the link and the good gee wiz info. It was all a very interesting read for me, and I learned a new word =)
on another post someone talked about these batteries. They say they can be discharged to 2v per cell with no perminant damage, so cutt offs and timers are a thing of the past, or so they say. Seems like there has to be a catch. What they are saying just doesn't add up to me, it partly sounds like a TV infomercial. I mean do they have the technology, and that is just how they are marketing it? Or are they streching the truth and making it sound like the miracle battery pack of the future?

Back to Serious now..
Air Thunder Battery:
Throwing out the cost for any battery and just chewing data.
I went to the web site, and watched their 9 minute video of someone flying a TREX 450 for 9 full minutes, that's a windfall. Very good for the Trex on one charge.
I believe that the company is rather new and so is the technology behind their product.. I believe their batteries will do as advertised.
Technology advances so rapidly in the electronics field today, it make your head spin.
Currently, they have only 6 batteries available and only 1 that is 11.1 volts at 2200 mAh. The weight of the battery is 6.7 oz. or 190 grams. That would be pretty heavy for a CPPro. The Pro stock, without battery weighs in at 298 grams. Together that's 488 grams.
The size of the battery is 1.18 x 1.45 x 4.44 inches. I'm not sure that would fit in a stock CPPro battery tray, it would fit in the Super-Skids. See attached picture.. for comparison in size of a thunder power 2100 mAh battery(which is almost identical to the Air Thunder) and a E-flite 860 mAh battery.. Also, note that on the picture of the E-flite battery(alone) you'll see the Thunder Power logo.. Hmmm, does TP make the batteries for E-flite. (BTW, the pictures are lousy, but viewable. My photograhpy skills are limited to just pushing the button).
NOTE: The E-flite battery was manufactured on 1/09/06, purchased some time in May of last year, I couldn't begin to tell you how many charges are on it, but I still get a solid 10 minutes of flight time.
