GoPro Hero 3+

[NordicCrankShaft]

Got this last year for Christmas and used it quite a lot for various things but one activity in particular where I used it in connection with the GoPro app on my android phone it absolutely killed the battery in the GoPro because the wifi needs to be switched on to connect to the app. I could jut not use it with the app, but it's so handy to be able to have control over the camera with my phone.

Is it possible to buy better/bigger batteries?
