This goes along with many of the problem symptoms I've read about with the H3B (shutting down, corrupted files etc...) It's not a charge level issue, the batteys are misreporting the level of charge to the cam.
GPs customer service is replacing them as we speak.
Two key issues not mentioned in the documentation:
format the micro SD card with the camera prior to filming.
2) Use a wall plug USB charger, 1a rating is preferred. Do not rely on charging via a computer's usb port, it does not supply enough current for the GoPro.
Definately buy extra batterys if you go with the new GP, the average runtime is a little over an hour per battery @ 1080P/60FPS, Wifi will reduce that a little.
If they come out with a skeleton case for the H3s I'll probably run a 64G card and a remote battery pack (4 hrs of video) The H2's 2 hr recording time has spoiled me.
