How long does the GH2 battery last for you guys. My experience has been pretty bad. I have two OEM batteries for GH2 and each one only lasts 30 minutes of recording time. I have a GH2 hacked with Cake 2.2. Went to the zoo yesterday and had my dad recording video with it. Shot in high bit rate mode hacked and took over 200 video files with around an hour of footage. So yes, a lot of 3 or 4 second clips included in there. No sure if that taxes the battery more having multiple shots vs one long recorded one. That dried up both of my batteries. Thanks.
