Yeah I do not have access to my old high school physics info. That part of my brain has long since calcified.
If 2 CR123As are filling the space of 1 18650, then they would be stacked in series (like a tower of minions in a trench coat (why does the internet have no picture like this? I could have sworn they did this gag in at least one of the Despicable Me movies!))
the webz does say it's in there, but not giving me pictures...
