I really don't understand now. I thought the Hero 3 is smaller than the Hero 2. So, is the Original battery bacpac an accessory that's made specifically for the Hero 3? I was assuming, from the name and it's location in the menu on the GoPro website, that it was made for an older model camera than the Hero 3.
