John,
I have one but I tend to run out of memory long before I ever run out of battery?

I want to say I get roughly 5 hours out of each battery and I have several 8g memory cards.

I know my buddy has the extra battery pack thing and that may help?
But I just carry a spare all charged up and all together that seems to easily take care of a weekend, selectively filming of course.

However I am ordering a goalzero solar charging kit, just to help facilitate in any battery troubles I may run into while on the river.

Good luck with that and I am already looking forward to any clips you end up putting together!

Cheers,
Watson
