Gotta update this for everyone, just ordered one from Amazon and it was $15 plus $3 shipping. I have the Naztech 2500ah battery and its amazing you can't kill the phone no matter what you do (calibrating the battery is fun lol) but no protective case fits it- and I paid for that last week I dropped my phone and the screen broke (phone still works great tho) so for when I'm at work here I need a battery that will fit in a case. I'll save the Naztech for when I'm walking in the woods or something.
