EOS 5D Mark IV: Timelapse Movies and battery life

When shooting a timelapse, it is likely the camera will be active for a long period of time, and as such battery life becomes important. In normal shooting conditions, with a shooting interval set to 1sec, the EOS 5D Mark IV with a fully charged LP-E6N battery should last around 3h50mins. For timelapses lasting longer than this, either a battery grip with two batteries (double time) or a mains adaptor should be used. At lower temperatures, the shooting time will reduce.
