Thanks Barkuti!! 
I guess that is relevant enough, despite my great ignorance about those readings!! Hum, Iām gonna risk on the Pkell, buy 2 and hope they are nice enough to the incoming flashlight
Unless others like the āOn the Roadā are sold in any place, but I donāt think soā¦
Muchas gracias :+1:
Something for a side note. The Windyfire IMR16340 600mAh cells clearly look like the TrustFires, and it also happens that the TrustFire and Windyfire IMR14500s look and had similar performance in the reviews.

Ditto! 
I get my batteries from Aussie eBay seller supersports600. A big more expensive than from China options, but the 3 day delivery and customer service is worth it! He is involved with Keeppower so knows his stuff!

Max continuous discharge current is only listed as 2A though, which is too low for my liking. That said, I still have no idea what max discharge current is on the Lumintop 650mAH batteries I bought. Canāt seem to find any info in relation to this on my internet search.
Max. Continuous Discharging Current: 2C
Thanks for this info. I have saved him on my ebay profile, always good to have another reliable source of battery supplier. 
I contacted Neal about the On The Road 16340 battery.
He was surprised when i said they were one of the best (high capacity and current), ad asked for some more test results.
So iām looking for test results, canāt remember where i saw reviews of that battery.
Maybe it was a Youtube review, iāll have a look in my āwatch historyā.
But i think it would be great if Neal could source those cells (either with or without the OTR wrapper).
Maybe you guys can help finding test results.
I recall seeing something on David Sunshine channel, in his review of the OTR M3! Canāt be sure (and canāt check now as Iām not on the computer)!
Yeah, thatās where i got the high capacity measurements from.
He says itās 799 mAh.
But another (more recent) review i just watched says itās 600mAh.
So now iām not so sure anymoreā¦ :person_facepalming:
By the way, i got 4x āPKcellā 16340 in yesterday, they seem to hold up fairly well in the M3.
I will try to do some tests later.
These are 2 reviews that analyse the battery. The first one is about the OTR U16, and the second about the M3.
Maybe it was here youāve seen it?
Also, a quick insight on the batteryās voltage, in their branded charger: ENEDED .
And this post from The Miller about the capacity: Are these OTR M3 runtimes normal? - #7 by The_Miller .
Last week I sent PM to Neal asking about the same thing, about if he sells good 16340ās!
To not overload him with PMs and all that stuff, if you are in contact with him, can you take care of this and them return with some answers, please?
Iād be interested to get some good 16340s and of the OTR is one of the best, and he can arrange some, letās do it!
Yes, please tell something about those too!
I ordered a 16340 flashlight (Jaxmnve M3, on AliExpress) and wanna buy some cells. But canāt be sure if the PKCell are good or if I should try the Trustfire IMR. So, if you have some insight on those, let us know please
I still use a few aw 16340ās (red ones) not the best but working fine in all of my highish drain 16340 lights.
I received the two Lumintop 16340 batteries purchased from AliExpress as well a couple of days ago. Will pop them in my Liitokala Lii-500 charger to check capacity.
Thatās great.
When you pop them into your M3, do you visually see a difference in light output between high and turbo?
Okay, so i did a NOR test on my Lii-500 with the 4 PKcells.
Theyāre all around 700mAh, may improve a little because they were brand new.
The internal resistance guestimate of the Lii-500 are inconsistent wild guesses, so it doesnāt mean too much, but it seems these PKcells are a little better in that regard than Sanyo 14500.
I think these PKcells are similar in performance to their 14500 cells.
My M3 draws 2.28 A on āturboā (according to my UNI-T clamp meter) with a freshly charged PKcell,
with a āhalf fullā cell (3.6 Volts without load) itās 2.24 A.
with a 3.5 Volts (without load) cell itās 2.05 A on the clamp meter.
So this is where it apparently starts to suffer from the sag too much. 
I will calculate the internal resistance now, iāll get back to you with that.
Just remembered the Windyfire brand market its cells by themselves: http://www.windyfire.com/windyfire-imr-16340-600mah-3a-button-2pcs.html
http://www.windyfire.com/windyfire-imr-16340-600mah-37v-3a.html -> In the past you had to ask for a cheap shipping quote. They may still do it for those of you outside of the countries listed in the above link.
Cheers 
And the plot thickens
Thanks for the test Jerommel and the heads up on their site Barkuti!
Letās see if the PkCell and the Lumintop worth a try. It they are nice, why not?
If they are not, Windyfire may be an optionā¦or the Trustfire IMRā¦or the AWT IMRā¦or the On The Road :person_facepalming: :person_facepalming:
Okay, i calculated the internal resistance of one of my PKcells, i think i did it right.
The Voltage of the cell was 3.5 V without load.
I put on a load with a 1.35 Ī© resistor, giving a Voltage of 3.2 Volts over the resistor, I=U:R so the current was 3.2 V : 1.35 Ī© = 2.37 A
Now i can calculate the total resistance. R=U:I so R = 3.5 V : 2.37 A = 1.47 Ī©
Subtract the 1.35 Ī© from that, so 1.47 - 1.35 = 0.12 Ohm or 120mĪ©
When I (current) is 2.3 A (M3 turbo mode) P (power) wasted as heat in the battery is P=IĀ²ĆR ā> IĀ² = 5.29 ā> 5.29 Ć 0.12 Ī© = 0.63 Watt heating up the battery, which is nothing to worry about i.m.o.
Anyway, with Ri=120mĪ© this is not a high drain cell at allā¦
PS: The numbers could be off by 15% (or something) due to my equipment.
Unfortunately the batteries got to me first from AliExpress, even though I ordered the OTR M3 from GearBest at least a good few days before the batteries. Hopefully the M3 will turn up next week.
