Battery-powered Pi?

mgt6910

I would like to use my Pi on a robotic platform, for which an onboard power supply will be

necessary. I  have a rechargeable 6-volt battery. How can I regulate this down to 5V ?

    The numbers I've seen from someone actually measuring current draw was 550 mA, but the official spec is 700 mA. I think this may not include power drawn by USB devices connected to the Pi's two USB ports.  The Pi has three linear regulators on board (check RG1, RG2, RG3 on the schematic), so you can guess it wasn't designed for the highest efficiency. The CPU core voltage is generated by a switcher integrated on the SoC, though.
