powerbudget of freerunner?

[joakim at verona.se]

What are the power requirements for the different parts of the
freerunner?

I would like to calculate how large battery capacity I need to have all
the subsystems running(wifi, gps, gsm, bluetooth) + an external 3g
modem. I would like to have 24h continuous uptime without suspend. (if i
need a car battery to do it, so be it :)

Also, is the coulomb counter interface some kind of standard? is it
possible to buy a laptop battery which implements the coulomb counter?
