After reading a few reviews on here about the generic eBay extended batteries and the overpriced Mugen extended one I decided on the Hyperion 5000 mAh battery.
Performance so far has been GREAT, twice as much as the stock battery probably more - i got 6+ hours of screen time! I would definitely recommend it over the generic eBay crap and the good but WAY overpriced Mugen battery
A 7500mAh battery should be fairly easy to make. Just look at this picture I just took where I placed 2 batteries on top of the existing stock battery (3x2500=7500mAh).
If a TPU case for the extended battery cover is released I might try this for real (using double-sided tape and some wiring). With a TPU case I might get away with not using a back cover at all.
OR... the best solution would be if a manufacturer would be inspired by my picture and actually make a professional version of it.
i purchased one of hyperion's 2600mAh slim battery for galaxy note a week ago, 2600mAh is 100mAh more than stock battery, which means it should last a little longer than my stock one. but after few days use, i feel hyperion last much shorter.
i rip off the label of hyperion battery, guess what?
it's marked only 1750mAh under the label !!!! what a kind of joking!! i'll never trust this brand again. i believe their 5000mAh extended battery is a fake as well. some one who have this battery can try my way.
