Probably will not work as the AA (don't quote me) will only handle less than 10 amps discharge. sub c's will spike over 100 amps ok.

You can probably use them in application where it takes about 30 minutes to discharge, any faster and they will not hold up. Again don't quote my exact figures, but they are for radio and low draw applications.

Great idea though, I had the same idea.for the same reasons as you, low cost and pow wheight, the sapacity is almost the same as sub c. If we can increase the voltage by using more cells, then cut the amps down it will be better, but then we are dealing with more weight again.

Another idea is there are in-between cells that will deliver 30-50 amps . They are either 1100-1200 or 2000 nimh cells and may be called 2/3 A ? I'm not real sure they are popular with airplane doods.
