Battery Life in Cold Weather
I was excited to use my new GoPro Hero3 Black on a snowmobiling trip this past Saturday only to come away with mere 10 minutes of video. I was using the remote (a great invention BTW) which was attached to my glove. Really handy, as I used to have to look in my mirror, fumble for buttons and watch for the flashing red light on my Hero 1.
One would think that the technology would get better over the years and not worse. I never had a problem with my Hero battery when I went out sledding. I used to carry a spare and I could shoot 2 hours of total video in the cold -25C or 13 below.
I spent the morning looking at ways to power the Hero3 externally. There were lots of ideas about modifying a USB cable to power the unit but then I read that using that port to power the unit can cause problems (corrupt video?).
Then I came across the DC couplers idea which intrigued me. One in particular, from Hardened Power Systems, which I saw mentioned elsewhere on this forum. This looks like the solution for me since I already have my sled setup for USB power for my 5" wide screen GPS or I can just run it off a Patriot Fuel or Antec Powerup battery inside my jacket...whatever. I think I'll order one and shoot a video of the setup! I need it for next weekend. So I better get crackin'! :)
I spent an hour in Zero shooing how to clean a windshield. I spent 5 hours via a external power source plugged into a usb, that was left behind in Granada. so I see no problems for me. where you charge the cam is where you plug those ext packs enjoyed the write up...
It is definitely important to keep the battery warm. I'm assuming you left the battery tucked away inside your jacket?
all batterys degrade in the cold
lithium having better resistance to cold compared to nimh, especially when idling/storage. but 10 minutes is not right. the battery must have not been charged or something was draining it prematurely.
