Presuming maybe? The capacity of the F1L is above 3100mAh at 0.5A typical analyzing charger discharge rates. It does not really match that well, and is a foreign cell anyway.
Maybe it is this:

This one matches better and is easily available in china. Sold under different wraps, Sofirn included:
Check here for related discussion.
Cheers :-)
Uhmm just wondering, are these batteries trustworthy?

My friend said they are pretty legit cause he has used these type of batteries before for his e-cig so im wondering if i should keep them or refund them
I'll try to avoid being judgmental but, unfortunately, your friend knows jack shit. LiitoKala is known to be making business selling fake batteries, and those cells are 100% fake guaranteed. Check the reviews, but check them well: select “Sort by latest” and look for additional feedback (AliExpress' feedback system encourages quick, badly done reviews with inflated ratings).
I see complaints by recent customers. You can also see this:
Genuine LG HG2 cells will hardly deliver ≈2.9Ah down to 2.8V at 0.5A discharge rate, you can check reviews like this one.
Those cells being sold by LiitoKala as LG HG2s are some kind high capacity, lesser discharge performance cells (maybe own brand LG D2 or F1L cells).
There are trustworthy places to get batteries from if that is what you aim for. Like Aliya's, Lucky's or NKON. 
Cheers :-)
You have a way with words Barkuti, I love it!! . 
. 
hey, i have this battery(exactly in the picture), the IR is about 35mOhm(measured with 4 wires probe), and the most important thing, it’s dirt cheap, less than $2 per cell, great for <1500 lumen flashlight
They’re not fake. They’re “LiitoKala Lii-HG2” cells, not LG HG2 cells. It’s perfectly clear! 
Wow! :facepalm:
Didn't pay attention to my own latest messages here. :-)
Yes, that DLG battery. With a 4-lobe top, very much like LG HG2 cells. Ticket to ride LoL!
:-)
There are still shops like Vapcell that sell genuine cells
not sure but I think HaikeLite can be also trusted

Just had 5 cells delivered from here https://www.aliexpress.com/item/32796443183.html
I'm thinking they are genuine,
Opinions?
No way!
Check my signature, by the way. Thanks.
I just got an 8pak from FT, all with 3 lobes on the top cap. Didn’t put ’em through the wringer yet, but they’re looking good so far.
I am going to be brutally honest here, this is a terrible forum script.
Fair enough, but this is a fairly old forum platform and merely requires some user interaction when posting images and such. There are fancier and more modern forums available, but they tend to cost money. This is a free forum, after all, and doesn’t even have advertising :+1: .
Nothing wrong with being honest, but we’re getting our money’s worth here :partying_face: .
Your 30Q’s are fake, though, as the terminal has too many legs. I seriously doubt that anyone has received genuine 30Q’s (or any other name brand) from any Liitokala seller (yes, there are many). Your measured capacity does seem quite close to the genuine cells and the voltage curve and figures even appear close to the real thing (bump at first 500mAh, drop-off at 2300mAh). However, testing them with a 5-10A load would likely differentiate them.
The ones in the pictures on the item page appear to be genuine Samsungs, so you can tell these are fakes by comparing them to LiitoKala’s own photos :person_facepalming: . Regardless, they seem like good 3000mAh cells for low-drain applications and I’d like to know how these cells perform at 5A or more. Has anyone tested them at high currents?
I personally won’t buy these, though, as I don’t want to support LiitoKalas’ (plural) fakery. If people know what they’re getting (3000mAh cells that happen to be pink), then it’s understandable that they buy these, but the stores should somehow be punished for their fraud 
. It’s fine to sell 3000mAh Chinese cells and even claim that they are similar to Samsung 30Q’s if they wish, but they should be labelled honestly.
Looking at the item page, I find it odd that they don’t mention Samsung in the tag line, images, or most of the text, yet they eventually state “100% Samsung Brand New and High quality” in the bullet points under “Features”. It almost appears that they’ve purposefully avoided including “Samsung” in the images and item name, perhaps so that it would be fast and easy to simply remove the single line stating “100% Samsung…” if it became necessary to do so for some reason. Hmmm…
…or perhaps “100% Samsung Brand New” simply means that they are just as brand new as Samsung cells .
Unlike Bangbad with their button tops and such, FastTech takes care; something quite understandable when you see the money you end up paying there what with one thing and another.
Wellp, conversely I can say that, despite a few hiccups, I find it terrific. :-D
If HenrysCat were to obtain a V(C) curve (voltage to capacity) like the usual ones, it'd be of help. Anyway, let's see if we can make some sort of comparison with the V(t) curves from Henrik:
/Samsung%20INR18650-30Q%203000mAh%20(Pink)-CapacityTimeHours.png)
/Samsung%20INR18650-30Q%203000mAh%20(Pink)-CapacityTime.png)
There are some shape differences like, for example, the nearly instant drop under 4.1V at the start for the non 30Q cell. 
The problem is that 1A isn’t high enough to see if they are at least acceptable fake 30Qs.
I mean, the top terminal has more than 3 legs, so it’s not a 30Q.
Anyway, could you test the cell at 3A or more, or give any resistance readings?
Thank you.
I’m cooking mine now. Can’t get consistent mΩ readings worth a damn, but then again I never could. The Ope isn’t getting heat-stroke — yet — charging and discharging at 1A each (all 4 bays loaded), so I should get some indication by tomorrow.
I typically get a consistent 30xxmAH with 30Qs.
You mean this? That's the only other way the software will display the results.
Currently running a 5A test, will post results when done.
The results are in :)
