If all you need is high current for a short time, nicad are the best in this regard. Nm-hd and lithium batteries have higher power density than nicad, but nicads have lower internal resistance, thus higher available instantanious current. You can probably pull 30-40 amps from AA nicads for a (very) short period of time. As far as capacity, AA nicads are now 600-800 mah or something like that. (A few years ago they were around 550) NiMHd are close to twice the capacity of nicad. Lithium ion batteries have about twice the power density of NiMHd. They are higher voltage per cell, so you use fewer cells in series and sometimes series-parallel them in motor packs for electric RC airplanes.
