Far too much. If you're only running 2 gearmotors on 2 cells you can get away with around 100mah minimum, and I wouldn't go above 150-180 unless you specifically want to have lots of run time.

I've usually used 120-180mah packs (at the moment I seem to be using the Hyperion ones a lot - they're a lot easier to charge too as you can get a 1-4 cell auto charger and just plug in and press one button), although I've got some 30mah cells for the nanoweight when that gets built!

Unless you're running a high current weapon you can probably run on one 100-200mah pack for most of an event, certainly three or four fights at least, without having to worry much about charging - I tend to have my batteries on Velcro so I can have one in the robot and the rest on charge or ready during longer events.
