Their SUPERcase, which is currently funding on Kickstarter, is looking to make GoPros more functional by adding a significant amount of additional battery life and storage capacity, in addition to a few other handy features like a 58mm filter thread.
Here's the SUPERcase pitch video:

And here are the main features and tech specs for the SUPERcase:
As you might expect for a case with this much functionality, it does not come cheap. The base model, with just one 5200 mAh battery and no additional storage, comes in at $100. Once you add in 128GB of storage, that price climbs to $230. If you want a fully spec'd out SUPERcase with a battery and 512GB of storage, you're looking at $455, which could very well be more than you paid for the camera itself. Frankly, that makes the SUPERcase feel extremely pricey, but then again, storage and batteries are almost always a significant investment with any camera, and if you're looking for an integrated solution that adds loads of storage and battery life to your GoPro, the SUPERcase might be an excellent option for you.
