Tired of your GoPro battery letting you down? Me too... So check this shiz out... P&C are calling it the "CagePro" and it lets you Power-Up your GoPro for more than 5 hours of run time on a single charge, using the easy to get, LP-E6 Battery (Used in Canon DSLR's).
So... That's pretty Kickass right?!
CagePro Powered GoPro Camera Cage; They're asking for a tweet (or FB like, if you must) to register your interest in having these things be a real thing you can buy...

"Our unique Patent Pending design solves several problems for filmmakers who use the GoPro Hero3 in professional production and broadcast environments. First and foremost, our cage offers additional mounting points - an important feature to minimise vibrations when rigging the GoPro to cars, motorcycles, planes, boats, and more.
Our most unique and innovative feature pumps power to your Hero3 through a common LP-E6 battery (Canon DSLR Type)! A single Canon LP-E6 Battery can provide more than 5 hours of run time on a single charge. A perfect solution for long video takes, or a full day of Time Lapse projects."
