Vamo Diameter?

[Coastal Cowboy]

I'm building a new PV storage/display block and have a Vamo 3 on the way.

[Hush it, Bill and Tracey. I'm only gettin' one!]

What's the diameter of the device? eGo's always slip right into a 5/8" hole, but I'm sure the Vamo is bigger and need to know what size drill to use.

It's 22mm.

It's 22mm.

Thank you, sir. I just happen to have a 7/8" quick bore in my arsenal of drills.
