Why exactly? 
I’m going to take back my Banggood recommendation for batteries, at least for their button-top 30Q’s.
I’ve bought a total of 9 of those buttop-top Samsung 30Q cells from Banggood, and now I’ve had 3 of them go bad. Suddenly, their self-discharge will start rising to unacceptable levels. I’ll get noticeable voltage drop every day (up to 50mV) from 3 of the cells, without using them. At best this makes them unusable in multi-cell lights (for a series config). At worst, this might indicate an internal short and make them dangerous.
Flat-top cells I’ve bought from Banggood appear to be fine. It just seems to be an issue with the 30Q’s that have an after-market button added. I’m not sure if they’re getting fakes, or it’s a bad grade of cells. But whatever the reason, make sure to check your button-top 30Qs.
Thank you for this all inclusive list.
I can’t seem to find a place to purchase 2 pcs of Keeppower 18350 1100mAh with affordable shipping to US.
Sofar it looks to me like it costs $18-$20 with shipping for 2 batteries
BG is maybe $15 which is still ridiculous for a place with bad rep and slow delivery.
I once tried ordering a couple of batteries from an AliExpress store, and was mildy surprised to receive 2 generic “T6” zoomable flashlights (which had lots of scratches, but I tested them to work). My ordered batteries were placed inside the flashlight (wrapped).
Unfortunately, almost all other AliExpress stores now have stopped shipping bare batteries to my country. The only ones remaining that ship batteries, use DHL or Fedex or other expensive shipping ($50 to $100+ shipping fee) — I have not tried these latter shipping methods, so it’s now been more than 1 year that I have ordered bare batteries from foreign online stores. The only ones that do ship are the ones included in flashlights (eg. the Sofirn flashlight with battery kit).
Maybe I should suggest to the AliExpress stores to try the above technique (place the battery in some cheap disposable electronic device) — this will work for few batteries. Because I think there is still a limit of around 2 flashlights with 2 batteries per shipping (for the postal shipping), The more expensive DHL/Fedex shipping likely have a higher limit on the number of batteries that can be shipped (but still need to be placed inside “containers”).
If I understand it right Lithium batteries need to be shipped inside a container that will prevent any short circuit .
Would these inexpensive plastic containers work?
Depends on where you live.
If you live in Canada, the customs will just seize it.
If you live in the US/Europe, you’ll have a bugger chance of receiving it normally.
I guess CBSA chart changed since this one. War on Lithium! 
Looks like the only reputable seller who still ships to Brazil is Sunway Store Aliexpress 
Has anyone already tested their “AERDU” new cells?
Question about Aliya’s Battery Store https://www.aliexpress.com/store/all-wholesale-products/1382210.html
> Has anyone received any shipments recently (to Canada), from Aliya’s ?
> How does Aliya’s ship ?
> Can/will the CBSA confiscate battery orders from Aliya’s ?
Thanks Knobby

1. Yes I have received them fairly recently, no problem there.
2. They ship via a special forwarder that ships lithium ion cells safely and legally. It does cost more, but it is worth it for the next point.
3. It will never get seized by customs, since it is being shipped via perfectly legal means.
It first ships from China, then to a USPS hub to ship both in Canada and in the US via Ground Shipping.
So, yes, you can be perfectly assured that you will get your 18650s.
So, guys and gals, don’t forget that you can contribute to sources here.
I haven’t found anyone cheaper than nkon.nl for European customers and i’ve been looking around a lot.
If anyone knows anyone cheaper, please tell
I would be buying like 50-100 cells.
great list - I remember when the big sellers in Asia would sell authentic sells for 2 dollars after points and free shipping, guess these days are over.
I had forgotten about this thread…
I bought some NCR18650GA on ebay.
The seller resides in Serbia.
The batteries are genuine, but they are 2 year old (code date: 7216).
They are not cheap but is a seller that sends to my country.
The next will be: https://www.ebay.com/itm/Battery-SAMSUNG-Li-Ion-3-6V-3500mAh-INR18650-35E/163397766612
What’s the turnaround time for an order for Aliya’s battery store? I have an order dated 30th April and it’s yet to ship out. No replies when contacting them on shipping status. Anyone dealt with them recently?
Between May 1st and May 8th, there were the labor festivitities.
I would send them a message just in case.
Thanks BlueSword, I was under the impression that the holidays were until the 4th May. Guess I’ll just wait a little longer.
So I picked up a couple of batteries from “The Lithium Guys” in Australia. Interestingly they appear to sell their own batteries that they claim are OEM LG or Samsung. I’m curious to see how they perform, as they’re suspiciously cheap (AUD $15 for two)
Couple of photos of the cell and data sheet that came with it.
Opinions?
Hey guys, I specifically want a vapcell 16340 that can be purchased in the UK with quick delivery in the UK. It wouldn’t hurt if I can also get 25R’s or VTC5a’s from the same place. Any advise please?
Some very good new for Canadians.
