Post GODOX LP-800X
Hi Guys,

I've been asked to shoot a timelapse for 23 days for up to 12 hours each day. Due to the risk of theft I'm going to have to set up each morning, so leaving the camera is out of the question.

I'm looking for a battery solution to power a 5D MK III for around 12 hours, shooting around 4 shots per minute in raw. Although expensive, I found this device - http://www.theflashcentre.com/godox_lp-800x_lithium_ion_power_inverter.html. I'm unsure of the maths involved to make a calculation but the retailer tells me that it's more than enough power to run for a day. I know it's overkill but I quite like the features and ports of the device to use in the future when on the move.

Would anyone be able to tell me if that is indeed the case. Is it enough power in theory? Naturally there's many real world variables to take into consideration, but does this tick the mathematical box?

Thanks a lot for your time.

I forgot what I ran during an event but I think it was either 30 or 60s interval.
For that I got about 12 hours of JPEG photos out of gripped 6D and 5D3. Around 1,200 - 1,400 photos depending on when I swapped batts.

Are you using an 128gb CF card? 4x60x12 = 2,880 photos. 5D3 has like what, max 1K photos in RAW on a 64GB card...
(Unless you mean you have a 128gb CF card and a 64gb SD card.)
If you are swapping cards you might as well swap batteries...


As for batteries - Sony NP-970 is ~6,000maH I think.
LP-E6 is around ~2,000 maH.

Just make the DIY DC connector and hook up 2x NP-970 and you have ~12,000 maH, or 6 LP-E6s.
That should definitely last you 24h. Cheaper than spending $1,000 dollars on a power supply.

Or you can just get a lithium ion battery like the Anker 20,000maH and just hook it up to the camera.
You will probably need to step down the voltage.
$80 for Anker battery
$30 for LP-E6 DC adapter
$2 for voltage step down board
+ $5 for parts.

If you are doing continuous coverage then you need 2x Ankers per camera as you will need to swap.

Many posts on these sorts of things on google and this board.

Just posted this battery http://www.tracerpower.com/lifepo4-12v- ... -pack.html

It truly is the ultimate. You would need a voltage converter for powering your camera off it, but I bet it would power a shot for weeks and weeks.
