Canon 6D Timelapse overnight with a Powerbank and no shutter count!

Have you seen the beautiful Time-Lapse videos, some on 4K that are all around the internet?  Some have increased dynamic range which gives a spectacular effect and changes the way we see the world (in fast movement).  Seeing the time passing by so quickly fitting 2 or more hours in a one minute clip is something that drew my attention, but I was always scared of the large shutter count it would need before the video length was enough to watch.
