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!
By 46100 do you mean 4680, the new Tesla format?
32650 is pretty close to a D cell. I wonder what they were thinking.
I did make up 461000 but there are a few variations coming out with 46mm diameter, based on the popular format you mentioned but different lengths. And the poster of this BLF thread mentioned Lumintop GT110 which uses a 46110! (110mm not 11mm).
Interesting about these large single cells displacing multi cell lights. I guess the vendors don't trust the cell quality and/or BMS. This is all lumenitis anyway imho. By the time a light gets this large, maybe you want a night vision scope instead.
It kind of makes sense if you look at the geometry though. Look at the wasted space in the 3*AA holder and think how many more Wh you could get if that space were filled with more anode/cathode/electrolyte.
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.
