Something new from Sofirn. These larger cells (than 26800) seem to be popping up in flashlights more often now. This one lists 6500 mAh which isn't a much bigger capacity but presumably the maximum discharge must be pretty high to support 12000 lumens.
Sft-40 in the center surrounded by flood emitters. This isn’t one I’ll be picking up, maybe I’ll hold out for a 461000 cell!
There are some adapters that squeeze four AA's into the D cell format. This is theoretically a little too thick, but it will fit in many devices where the battery tube is not too snug.
By pure volume a D cell is around 7x an AA.
