The mAh for 4s, 6s, etc depends GREATLY on the vehicle, gearing, usage, etc. You could have a heavy vehicle geared high that would need a lot more current than a low geared, lighter vehicle. There is no hard and fast rule, but generally, if you pick cells with a true 120-150A rating, you should be good.

And it's not really the mAh rating, but the combination of mAh rating and C rating. The mAh spec hints more at runtime. A 3300mAh 50C cell has the same current capability as a 8000mAh cell at 20C. Granted the 3300 cell won't have much runtime, and high current is less efficient.
