External Battery Case?

[iPreferAndroid]

The Samsung Galaxy S3 has a myriad of cases available to it. The ones that get my attention are the external back-up battery cases. I use a lot of battery in a day, and having both a more powerful battery in general as well as a backup battery case would be really helpful. Are there any cases that you know of for the Evo V 4G/Evo 3D (I know they are the same, but the product name may not be) similar to something like this?

No, the best that you can do is get an extended battery with a flat back, and get the generic tpu case to match. AFAIK this is the only extended battery and case solution unless you want to spend $50+ for the Seidio setup.

Do you have a link to the case?
