I don’t know I didn’t get one yet, but this makes photo makes me think maybe not?

Thanks, looking at the + post on the driver I had a feeling flat tops could be in issue,
I’ll stick with button tops then.
hi friends all,
so many threads in so few days…I cant read and reply smoothly, it will need too much time to read every threads carefully……
the middle modes is powered by PWM which works at 500 Hz, and it will not be seen by your eyes. but maybe seen by a camera, and I think the middle mode will be seldom used in most time, so I choose PWM for a convenience. The low and high is not PWM.

hi, the design of anti-reversing of battery forbids full flat batteries to work.
So flat 14500 batteries can not be use in this flashlight. You can use 14500 with a little higher cap like AA batteries, and I have this kind of 14500.
if dears cant get the battery,I can give you as a gift——need you leave a word in your order—-only few pcs this battery.
while,if you use 14500,the E3 will lost low and middle modes, it will be only one mode—high mode.
I am worry about if you can know what I am saying…
best regards
The english is not perfect but we understand it fine 
I understand completely what you said jaxman 
I will get one of these flashlights Thanks for your work!
Oh, and please consider to sell the flashlight host, because we like to make mods here 
I want learn a good English ability from all of you.
I found it is hard to get the truth ability of foreign languages if you are not live in the place of that language.
Ok, since all of us are the man who love DIY, I fully understand what dear all are thinking.
Host is not a problem. but need some time, now we are too busy to making business. Later, we will make a link for the host.
That sounds very nice, thanks for making it possible!
Well done Jaxman! Well done! 
+1 jaxman Thank you very much!!
Thanks! I’ll likely order one and leave a message to request for button-top 14500… Hope shipping flashlight+battery to my country won’t be a problem (unlike shipping of pure batteries)…
Single mode (high only) on a 14500, I take it you’re planning on modding with a different driver?
Anyone else think 22.5mm is kind of thick for an AA/14500 light?
I’d like to know where that measurement is taken, head, tail, or thickest part (anti-roll hex)
I have to wonder will it be much different in size from an E2 or S2+ w/18350
It looks like the E3 is not as lean as the Tool AA but still ok, and it is pretty short.
With the Tool AA, and with my 4sevens mini AA I have the feeling that if I drop it they could deform and the threading gets stuck, the E3 can be overrun by a truck.
Yes I see that, looking at this photo I’d say maybe even overrun by a tank!
.
I wonder if the 22.5 mm is the thickest part (anti-roll hex) or the head or the tail?
Jaxman, can you confirm it?
It does look small in this photo.
.
Could probably even drill that tube out for 16mm:
………………….Max Discharge Current: 18A…………………….
measured lumens with NIMH?
I want to use 14500 and have all modes, plus some increased output (Nichia 219c)
So I was thinking to swap in one of this driver:
Qlite 7135*8 w/guppydrv or NLITE
or
Convoy 7135*8 w/Biscotti
Anyone have an estimate of max lumen output for nichia 219c with the 7135*8?
.
Looks like it already will have copper DTP.
So this is begging for a driver upgrade!
