I bought some from https://www.18650.uk/ that I was happy with. Where tags have not been available, I have soldered to the cell, but there is a knack to it.

I think it's because of the postal regulations - IIRC you can send lithium batteries "in" something, but it's much harder to send batteries on their own.

I get batteries sent on their own, never been an issue. I know the post office always ask me if batteries are in whatever I’m posting. Never is as I take the batteries out.

As for the discharge current I'm not sure what the standard ones are, I would guess 20 /30 amps .

Open up the battery pack and look for the number printed on the cells to Google, you should be able to find the specifications for them.
Ive removed the cells from a few makita 18v 3ah batteries and although all different types, they were all 10a discharge cells

As said above ecolux is good for batteries and they will be genuine. Always buy good branded batteries. Be it 18650 or drill batteries.
Better to rebuild your own drill battery with good batteries than chinese scrap off ebay.
To many smart boys trying to save a few pounds on ebay but it always comes back to bite you.

Im after a single 18650 battery, Im fed up of trying to look though spec sheets. although Im only after a continuous discharge current of 4 amps, Im needing it to remain over 3.3V for as long as possible (20-30 minutes), so Im thinking of one with a 20 or 25A discharge to keep the internal resistance down (and keep the voltage under load up).
anyone able to recommend one that's suitable?

I have a few cells that I’ve nicked out of old laptop batteries. I have absolutely no idea what the discharge current is likely to be, but you're welcome to try a couple of you like.
thanks for the offer,
but I'm guessing that for a laptop they will be higher capacity low discharge currents.think I might get a Sony VCT6 battery. there are some better spec batteries out there, but trying to find them is stock in the uk is another story and not wanting to get fakes off ebay.
so there's not more replies I'll order one of these tomorrow night.

Torchy did a lot of work on how different batteries performed. I haven’t been on his web page for a while but all the batteries he sold, he tested. He had all the graphs there for you to see.
Go into Lidl & buy one of their 20v 2Ah drill batteries for £14.99. Inside you'll find 5 good quality cells which someone online thoroughly tested & hinted that they were Samsung cells rebranded as the results of the tests were similar & the cells looked nearly identical!
As to why its difficult to buy Li-ion cells in the UK - most of the main couriers refuse to carry them, even nicads & nimh. The airlines will not carry them so they have to go by land. You can buy them if they are in a battery along with a power tool, but the seller has to jump through a lot of hoops to get the courier to accept them! Allegedly Yodel will take them, but their T&C's are as clear as mud on whether they will take them!
As to why I now know all this, I have been trying to buy power tool batteries online without much success. The sale goes through but once they discover I'm in NI & they have to fly them here suddenly they 'cannot ship to your address'.
The only success I've had was with sellers who used Yodel as the courier. I'm guessing their stuff comes by boat as they are so slow!
I have recently noticed that banggood will now ship batteries to the UK so I'm guessing they have found a loophole somewhere!

The regulations regarding shipping of lithium batteries are well defined and depend on, amongst other things, chemistry and Wh of the shipment. But in general, lithium ion cells cannot be shipped on PASSENGER FLIGHTS and if shipped on cargo flights should be at 30% state of charge. So it's relatively easy to ship internationally with a dedicated courier providing the package is correctly labelled.
thanks guys
if you want to know why I just want one cell its because Im thinking of making a small ducted fan model boat, rather that using a propeller for propulsion, so I cable tied one on a model trawler hull to see if it would work.
and just behind it is a model planing hull that someone gave me that should be more suitable. not to go a bot off topic
so after playing with toy boats this morning, I was made to play with model steam trains.......I did my best to try and get out of driving an explosion waiting to happen but eventually gave in and did I as I was told.
