Joe,

Assuming that you need uninterrupted power longer than the battery provides it is possible to use a power adapter kit. I believe the M6ii battery is LP-E17 and that the camera has a trap door on the battery compartment door. If that is correct check this LINK . Using the power adapter opens up all kinds of possibilities for extended shooting but does require 110v. If the shooting location is not convenient to 110v the solution is to use an INVERTER .

Using a Canon M2 on a tripod I used this setup with each of these components plus a 12v lawn tractor battery to shoot the solar eclipse a couple years ago. My goal was to shoot a 6 hour time lapse and, even with the smaller lawn tractor battery, I estimated that I had at least 24 hours battery capacity. This setup worked flawlessly.

There are other adapters and inverters available but the two units listed above worked quite well for me. This might work for your needs or at least point to a suitable solution for your needs.

Thanks JRET. Very helpful!

I have the power adapter for the LP-E6 battery and used it last night with my 5D4 on the back deck plugged into power.

However, I want to be able to carry a battery with me to remote sites when things go back to "normal". So, weight  is a big factor. I'm OK with a camera pack and R + lens + LP-E6N batteries for Milky Way and M6ii + lens for star trails and tripods, but not much more.

Do you think that I could use this adapter and the batterymentioned in the original post? Is there a simple way to calculate how much battery I need to last 8 hours? It's been 45 years since I had calculus and basic physics. So, please go easy on me here.

For what it's worth, last night, the LP-E17 lasted about 4.5 hours shooting 30 sec exposures with a second or two between each exposure.
