Hi guys! I have a quick question and I hope you can help me.
I have a Canon 6D Mark II camera with an external flash, and I'll be doing night club photography for approximately 5 hours. I'm wondering if one battery will be enough to last throughout the entire session, or should I consider having a backup battery?
Considering turn off all unnecessary feature also shut the LCD screen.
It's always wise to have at least a second battery. In addition to camera features, it will also depend as to what lens you're using. Some lenses would be drawing more power.
I agree with Ricky. I always have a spare battery and a spare card with me. I have a 6D2. Even when I'm using GPS, I've taken a thousand shots with one battery. However, this has not been continuous shooting, so bring a second battery to be safe. With two batteries you will have no issues at all.

A lot will depend on how you use the camera. Always carry a spare battery. If you turn off Image Previews. Do not do a lot chimping. You should be fine.
However, I would think you should be equally concerned, if not more, about the battery life in the flash. BTW, you may not even be able to use the flash.
