makes me wanna buy button top
fwiw Jackson and Hank are reportedly recommending H10 Button tops..
a dented flat top might press on one of the plastic coated components..
fwiw, H10 button tops are too long to work in a TS10. The F12 button tops do fit the TS10.
I just read a report that the USB-C 14500 that work in my TS10,
also work in the D3AA, even though they are protected.
the D3AA can pull up to 6A,
the Vapcel F12 1250mAh button top has a 3A discharge rate.
the H10 1000mAh has a 10A discharge capability, so would give a higher turbo.. I would opt for the higher capacity of the F12. I disable Turbo anyway. I dont expect any more than 300 lumens will be thermally sustainable in a light this size.. its more than enough for indoor distances anyway, imho
fwiw, there is a report of a difference in O ring on some early run D3AA,
in this pic we can see the O ring on the red body is quite small:
someone else posted the O ring on the black body.. seems more of a normal size..
which O ring did your light come with? ;-)
