But I use a Chest Mount Strap with my GoPro Hero4 Silver camera. Instead of mounting it on my helmet. Also, You mentioned about having to re-charge the battery daily. That is a given. But I have three identical batteries, along with a battery re-charger. So I will never run into a situation(before going on my ride) of all three batteries are not charged. I am still trying to figure out, how. To be able to take a spare battery with me. Without damaging it in any way.
