I know the tailcap spring can be redesigned to fit longer-than-D-cell 18/26650s, but what happens with 32650s? The smaller cells fit inside the recess in the tailcap, but I don't think 32s will do that. Is there a workaround?
Maybe I'm getting ahead of myself - are there any 32650s worth using? Any that would be an improvement over 26650s?
I am using feilong 32650s in a custom mag built by jayrob. 2 of them fit in a 2d mag fine. tailspring is shortened a little but no fitment issues.
its using the kd 2 li ion driver and an xml u2
They will fit, but as to how much better than some of the newer 26650 cells, I think it's a toss up.
I do have an empty unused 2D Mag, but what about 3 cells in a 3D body? Here's 3 18650s in a 3D, unprotected & only 65mm OAL, if the 32s end up this long or longer I don't think it would work...
Might be better all around to stick with some good 26650s, I know 3 of those will fit in a 3D.
32650s are expensive… at least good ones… i paid over $22 a piece for the two feilongs i have and they are 6000mah
in all honesty you are better off getting double the amount of quality 26650 for about the same price and more run time
edit: 3x 32650s would be very tight in a 3d… i have 3x king kongs with solder blobs on the + end and its tight in a 3d mag
The tail cap is slightly bored to allow it to fit over the end of the 32650’s, I have 2 lights that run 2 32650’s and 1 stubby that runs 1. All have a slight boring at the opening of the tail cap to allow the 32650 Novae protected cells to fit.
JayRob took my stubby down 3/16” from the leading edge and opened it up to 1 5/16” On the 2 that I did I took em down about 1/8” and opened em up to just less than 1 5/16” They all 3 work the same with the Novae 32650 cells I use excusively.

Same cells I use. Same method I use with the lathe with a 2D mag. I’m pretty sure a rotary tool could be used to do the same thing.
With a 3D mag, I’m not really sure if the extra length created by one extra cell would still leave enough room. Its possibly but I’am not for sure.
Ah well I just checked (not with an actual 32650, but with both alkaline & NiMh D cells) and the new bigger ID in the cap isn't so big that it'd compromise the threads. Close, but should still be enough meat left that it won't fall apart. (potential) Crisis averted!
Maglite + 3x32650+MT-G2+ 9A driver??
The Feiling 6000 mah 32650s from FT are not too expensive. 15,86$ a piece when you buy three.

I think that 9A driver is mostly a flop, there needs to be a way to disable that ridiculous overheat 'protection' BS. I don't think the driver itself is making the heat that's affecting it, it just happens to get smothered with the heat from the LED. It might work if it could be mounted separate from the pill but that's not really practical.
