I recalled that someone on the main 808 Keyfob thread had tried installing a new lipo cell in the cam. A quick search turned-up the post:
Bottom-line was that a single 240mah cell did not fit well in the case. My guess is that the 808HD is not going to have substantially more space in there.
There are lots of other posts in that thread about adding a port to the side of the case to run it off an external battery. My sense with the 808HD, though, is that it'd be way easier to either use the accessory AA power thing or build your own JST to USB adapter (with + on Pin4 per the research in this thread) to use an external pack on the cam's existing port.
