Battery switch
Depends on what you want to pay for the batteries...
1200 mah packs are relatively cheap. You can get 2 for the price of one 2400 mah pack. The packs are the same size and shape, and the plugs are identical... so cost vs run time vs what you plan on doing will give you the answer.
The 1200 mah pack will give about 7 to 12 min of goofing around in the back yard, or one appx 5 to 6 min race. (And the RC10 isn't very competitive any more...) It'll recharge in as little as 15 min on a timer type charger. (But let it cool for 20 min after running and 10 after charging... or you can explode the pack. BTDTGTS)
THe 2400 mah pack will give just under doble the run time. (heat losses add up) They take 2 to 2.5 times as long to charge... and if using that same timer charger,let it rest 10 min before resetting the 15 min timer.
With four 1200 mah packs and two chargers.. you can run your car almost continuously, just pit-stopping for 30 sec to swap packs.

An interresting thing about the 2400 mah and 3000 mah 6 cell R/C car packs... they weigh almost the same as the older 1200 mah packs, same size and shape too.... The battery technology has improved quite a bit since the Associated "RC-10" and Tamiya "Frog" came out. [img]i/expressions/face-icon-small-wink.gif[/img]
The ESC... doesn't care about battery capacity. It cares about amperage drawn through it. The ESC won't care if you increase the capacity of the cells, as long as you don't increase the number of cells. More cells would cause you to push a higher amperage through the ESC (and motor... and you'd go faster)
If the ESC is so marginal on current rating that increasing durration of run with a larger capacity battery will harm it... just accellerating up a hill would blow it in a couple of seconds.
All you have to worry about with the ESC is that is has sufficient cooling air. (don't let it get caked with mud.)
