The tank motors require a lot of power and I did not want to wear down AA batteries or 9v that quickly. The RC car community has spent a good bit of time figuring out small power. So I picked up a Dynamite 7.2v 1750mah battery and Dynamite Sport II charger.
Then used a plug to connect to the motorshield's screw terminal.
