A while back, I too was curious if AA's could be used in place of single GP3300 cells since they would fit better and have greater capacity when paralleled. So, I took some Duracell 2300mAh AA's, wired a set in parallel for 4600mAh and compared the discharge curve to that of a GP3300 cell. Even with the added capacity, the AA's dropped voltage quite badly after 10A IIRC.

Like others have said, these have good capacity, but only for low-current loads, like a receiver or transmitter pack.

I just saw some fast-charge AA's out recently. Since they charge faster, maybe they have a better discharge curve?
