AA cells? That's your problem. AA cells don't dump lots of power
very well. sub-C cells do. The internal resistance of AA cells,
especially NiMH AA cells, is just too high.
I imagine that the sub-C NiMH cells used by car racers would work
fine, but not really any better than the NiCd cells he's currently
using. Sure, they'd have more capacity, but they do self-discharge
faster and so I'm guessing they'd last less time between needed
charges (unless he's constantly starting his engine.) And they cost

I used two 6 cell 1500 mAh sub-C packs on mine. Works pretty well.
If you needed more oomph, try all three packs. The extra voltage
isn't going to hurt your starter motor ...

... which you obviously already know :)
