I have been playing around with ideas for a dive light and was wondering why the 18650 battery seems to be so prevalent for battery packs vs some similar like 22650 or 26650?
The Idea I have in might will probably use just 4 cells, and there would not be much penalty for a wider26.5mm cell vs a smaller 18mm cell.
on a similar thought path, I currently use Dive Rite BX-1 lights for back ups and they use a delrin sleeve to space out a 18650 battery. It seems like a 22650 battery would fit in there just fine. I might email DR to ask, but I don't see any reason this would not work, as both batteries are 3.7v.
