Here is my usb charger i'll be trying out during the EC. Its a regular old 7Ah 12v sealed hobby battery and a car charger unit i found at walmart for about 10 dollars. Plus a couple of slide connectors and i put a switch in the side just for fun. Capable of charging 2 usb powered devices at a time. The 12v could easily be topped off with a small solar panel for extended trips.

For our application we aren't too concerned about the camera being wireless and if we did want to mount it out of reach and wireless we can just use the stock battery. So here is what I came up with. I bought the parts from www.batteryspace.com including a 10.4 Ah 3.7v Li-ion pack. The hardest part was the battery facsimile which is made of a small block of wood, some magnet wire, superglue, paper, black sharpie, needle-nose pliers, tweezers, calipers and Lots of cursing.
The resulting setup should give us about 10 times the normal run time of the stock GoPro battery (a mere 1050mah). The tradeoff of course is the umbilical cord. This setup also seems ideal for long time lapse applications.
