It will take a few stacks since I think each run of NiMH cells only puts out about 2 or 3 amps (if I remember correctly). Then it takes 2 amps just to hold the two massive batteries at 14.5 volts.

Consider using Li Po or even better, Lithium Iron Phosphate. With NiMH, the output is typically the AH rating. That is, a pack rated 1 AH can provide one amp. With Li Iron Phosphate, a 2.5 AH cell or pack can provide 70 amps. Of course if the load is only 2.5A, a fully charged cell or pack will last a full hour. The point is, for higher current draw, Li based cells will meet the need more easily.
