"With the ability to record up to 4 Hours of HD video on a single 64GB microSD card, the last thing you want to worry about is battery life. The GOPRO HERO3 / HERO3+ is capable of far longer run times than the internal battery can provide. Once you've enabled Wi-Fi, or attach the GOPRO LCD BacPac, you'll be lucky if you can squeeze out a full 40 minutes. Sure, you can achieve an extra hour of run time by mounting the external GOPRO Battery BacPac2, but this means removing the LCD Touch Screen - our favorite accessory. So we came up with a better idea - the Tehkron CagePro."
"The CagePro also incorporates a 62mm threaded filter ring to further improve the image quality from the GOPRO HERO3 / HERO3+ Cameras. By adding an ND Filter you can reduce shutter speeds on bright days which can help to reduce Jello and Rolling Shutter effects. Or slap on a CPL (circular polarising) filter to reduce glare on reflective surfaces and enhance colour saturation in skies, oceans, and trees."
"Our most 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."
