If you notice, he actually didn't say that mAh lead to more voltage since there is a comma in his sentance.

Thanks for that. At least someone can read!
I'm gonna have a hard time responding to Jshwaa's post as most of his statements don't even make sense.
I'll try to spell it out as simply as I can.
mAh, see excellent explanation provided by Jazz32 above!
To elaborate on mAh:
A milliampere hour (mAh) is 1000th of an ampere hour (Ah). Both measures are commonly used to describe the energy charge that a battery will hold and how long a device will run before the battery needs recharging.
Discharge rate - How quickly can a battery discharge it's stored energy.
You can have a 2000mAh li-ion cell with a low discharge rate, say 1 or 2c. I don't care what you do to that cell, it's never going to put more power to your motor than a similar cell with a higher discharge rate, even if that cell is less than half the mAh of the previous cell. The lower mAh cell will simply drain faster and need recharging sooner.
As far as high mAh directly relating to high discharge rate, I don't even want to go there. That is pure falicy and should not be posted here. High mAh does not mean a cell will have high discharge. High discharge does not mean a cell will have high mAh.
Here's the answer to your "challenge". Not much of one since anyone could find that in less than a minute if they knew what they were looking for.

Do some reading next time buddy. Preferably BEFORE you jump all over somone. Please feel free to explain the difference in the above listed cells by your "multiply "C" by "mAh" to get discharge rate" theory.

Sorry for the thread jack. Back to the 9v idea, probably not the best batts you could use. But we're talking about a $40 car. Do what you want
