What battery for GoPro Hero3+ Black photo time-lapse??

[legrevedotcom]

I have a client that is asking if I could GoPro a time-lapse over an entire workday (8 hours). I'm imagining myself an exposure once a minute, maybe 2 at most.
I'll be mounting the camera out in the open with the bicycle mount if possible.

So I started looking, but mostly find people talking about different travel chargers, or people giving examples of battery life when filming continously.
The most heard about options I found were the Anker, the Limeade and the New Trent.

Have any of you tried doing a long duration time-lapse with latest GoPro? And if so, what setup did you use?

Thanks in advance...

I did a gopro 3+ job last week.

I was concerned about battery life - I then read the manual.

You can run them off the USBport and therefore the mains with an adapter.

Obviously you wont be able to do that while the camera is in the regular housing.

Battery life on the GoPro doesn't extend significantly when running timelapse (when compared to filming), maximum you're likely to get with a Hero 3 and battery back pack is in the region of 5 hours.

So, if you want to run an 8 hour lapse, you're going to need an external power source. The cheapest method would be to buy a new (standard) GoPro housing, drill a hole in the side to expose the USB port on the Go Pro, then fit an external USB power pack to the camera (e.g http://www.ebay.co.uk/itm/like/2213...ff11=ICEP3.0.0&ff12=67&ff13=80&ff14=95&ff19=0)

If you're expecting rain, then you'll need to do a bit of water proofing, the battery pack can be placed in waterproof bag, opening pointed down (e.g http://www.trait-tech.com/product/T...e-used-as-the-bag-for-phone-s-shell-blue.html), to seal the hole on the GoPro case, put a bit of self almagamating tape around the USB cable once it's fitted in to the camera, and then pack it out to cover the hole. Try and get as good a seal as you can, if any moisture gets inside the housing the lens will fog up.
