== Battery Space ==
The battery area measure approximately 6" x 5.5" x 1" (152.4 x 139.7mm).<br>
6" will stick out just a little bit, it seems closer to 146.05mm<br><br>
Possible candidate: http://www.all-battery.com/111volt-5700mahli-polypack.aspx <--I could easily fit two of these for 11400mAh.

== Power Usage ==
* Gumstix + Wifi: .5 amps @ 5.25 volts
* Gumstix + Wifi + Cam + 2 x Motors: ~1.6 amps @ 7.2 volts
* Gumstix + Wifi + Cam + 2 x Motors (switching motors forward/reverse): ~2.25 to 4 amps @ 7.2 volts

* Gumstix + Wifi + Cam + 2 x Motors: ~.9 amps @ ? volts / (1 speed setting / 50 cycles)
* Gumstix + Wifi + Cam + 2 x Motors: ~1 amps @ ? volts / (2 speed setting / 100 cycles)

== Type of Batteries ==
*NiMH - Recommended by Gumstix community.
*LiPo - Better power versus weight, but not as rugged and advised against.

== My Comments ==

I think I use use the following:

Robo/Gum/Wifistix

== Others Comments ==

The wifi modules are particularly demanding, needing about 500 mA when idle and instantaneous requirements up to 2A is not uncommon.

The GIB hardware reference says that it has a 400mA regulator for the gumstix. This is definitely too low to be driving wifi. The robostix has a 500 mA regulator and it's too low as well.

Four 1.2v NiMH AA 2400mAh batteries will run the Gumstix for about 6 hours.
