Anyone know what cells these are packed with?

Reason I ask is most current 5000mAh 2s packs for RC are 160mm long these are only 138mm long. For my application (pic in post #25) here http://www.rc-monster.com/forum/show...?t=9298&page=2 the shorter the cell will have a lot less over hang keeping the weight closer to the centreline of the car. I was going to use the Trakpower packs as I have heard they have the Enerland cells in them, but if these are of similar quality I may well use them.
Any opinions would be appreciated.
Cheers Andrew
