Battery for 19:1 Metal Gearmotor

What would be the best battery solution for powering the motor #1102 19:1 Metal Gearmotor 37Dx52L. I building a bot that will have 2 of these motors being controlled by a Dragon12+ board.


I have moved this post to “Other Pololu Products” since it does not seem to be about a Pololu motor driver or motor controller. On the other hand, do you have a motor driver or motor controller? Can you provide a link to the “Dragon12+”, or are we supposed to go search around for it?
