One battery or two?

What do you guys think?


Seperate power supplies for the motors and the µC or one batterij and some electronics to reduce the voltage :

9V for µC and 6V for motors

I would just use a good battery pack. RC packs are great and can run all electronics as well as motors without issue.  7.2v packs are pefect as well for stepdown voltage on 5v regs.
