Thank you, all. I'm so glad I came here to ask.
I just ordered

and
https://www.amazon.com/gp/product/B07XGDXD37/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
And, all's right with the world again.

I'd rather have Chubby Gorilla bottles.
So if anyone is looking for some smok coils the older models there's some TFV8 T12 coils that are $0.49 for a five pack they're the ones that light up. And then there are some other assorted I want to say TFV12 tank coils same price but for three coils that don't light up. They're all in the lower ohm's neighborhood and shipping is going to be at least $8.20 but if anyone's in the mood for some of those you might want to go check them out at Kanger wholesale AKA light fire distribution. I ordered some just to have a backup even though they are obscene coils that require at least 50 watts which isn't really my game. But I was making an order anyway so it doesn't really matter 50 cents is not much. As long as I haven't been misled these coils at least the TFV8 ones are the same baby beast coils that are going to be compatible with a large range of tanks but I am not personally guaranteeing that because I have never used these coils
Thanks for the tip. Although I didn't use that particular tvf12 coil, that price couldn't be passed up. I bought 50 boxes. I don't use drop in coils at the present time, but I have a stash for the time when I'm unable to build. With my bad eyes, that may come sooner than I'd like.
I posted on the page before this one, on Feb. 23, about those SMOK coils and a couple others they had then...that have since sold out. They're definitely a great deal, and the S/H is, too. Even shipping 100 boxes was less than 10 bucks. There's also a link in my post to compatibility charts that show the other tanks they'll work with.
Lol I'm out of practice. It used to be that before I would mention a obscene sale of some sort on here I would do a search to see if you had mentioned anything recently in that topic because 9 out of 10 times you had! You are the best
Confession: I have not been keeping up with this thread (or ECF in general very much).
If anyone needs 18650s, Molicel P28As are back in stock at various vendors. I just got a batch from the 18650BatteryStore. These are good batteries! I just got done testing a pair of them that I intend to put in service shortly.
AC internal resistance 11.75 and 11.92 mΩ. A batch of P26As I tested two years ago were all between 11.50 and 12.06, so I'm calling that the same. The only cells I've had that test better (lower) were VTC5As, but those are quite a bit more expensive (if you can find them at all these days).
Capacity: 2747 and 2744 mAh down to 2.8V. I don't like to go below 2.8V in testing, but I'm reasonably confident they would have hit the 2800 'nominal' if I'd taken them down to the rated 2.5V.
Conventional wisdom has been, "Don't stock up on batteries". Well, based on all the batteries I've bought used, and started testing several years go, I'm gonna say: It's not a problem to store batteries for several years if it's done properly. E.g: I have VTC5s that were made in January of 2014 that I'm finally going to retire after 8 years. These were used sporadically, never heavily, but they we not stored properly, and I believe if they had been stored properly, they'd still be performing decently.
Speaking of storing batteries properly: First and foremost: Don't put them in storage fully charged! Store them with a 40-50% charge. 3.6V is good. Second: Keep 'em cool. How cool? Stand by on that. I expect to post detailed storage temperature (room temp / fridge / freezer) test results this summer in the battery section of the forum. Come July, it will have been three years for a batch of VTC5As, and two years for some P26As.

I have used lithium batteries since the late 90's. Those early lithium batteries didn't have a long shelf life, but they got better in the early 2000's. As I still have lithium batteries from 2006 stored at room temperature and half a charge that some are still doing just fine today.
Am not positive, but I am pretty sure that storing lithium at freezing temperatures may actually harm them. And for sure, avoid using them until the temperature is 50°F (10°C) or higher. As frozen batteries have been known to explode. Putting them in the fridge has shownnot to help over room temperature. So I don't think you'll notice any difference.
I really love this video about lithium batteries. You might want to watch it.

At 1:12, Jeff says storing them in the fridge will last longer. And the lower the stored voltage, the better. Of course, not too low which also will damage the cell.
He also said and I have heard other studies for years say the same thing... that if you charge say a 2400mAh cell @ 100ma for 24 hours vs. the same battery charged at 2.4A for one hour, both will be fully charged. But the 100mA charge will do far more damage to the cell. As the clock (time) spent charging does the damage, not the current (up to a point). So the quicker you can charge the better for the cell. And also the less time cells stay from higher voltages (higher charges) the better.

Yet every detailed datasheet I've seen allows for storage at freezing temperatures. Hence freezer temps are included in my testing.
The big no-no is charging them while they are cold. That is indeed dangerous.
My test results after one year concur, but one year isn't very long. I meant to re-test last year, but circumstances prevented it.
It has been speculated that there is a sweet-spot for charge rate. Not too fast, not too slow. But I absolutely do not buy "the quicker you can charge the better". Fast charging generates heat, and heat is bad.
I've heard a lot of opinions on everything to do with batteries. On some aspects, like not letting them sit at full charge, the opinions seem to be consistent. Other aspects, not so much.
I never heard of a benefit from charging at higher rates before. I heard many times that it was less stressful to charge them at lower rates. I generally charge at 0.5W. And try to pull them out for recharging at around 3.5 if possible.
I store spares in the fridge at 3.6 which I heard was the best level for storage. Sounds from the above that maybe they should be stored at a lower charge.
Like with a lot of subjects maybe a lot of what I believe about batteries is wrong. On the other hand my annual expense for batteries is insignificant so a bit of marginal improvement in how long they last isn't something I spend time worrying about.
Likewise. I just in the last month or so replaced all my 18650s, after 8 years of use. (mtl tootler
) Still good in flashlights.Yup. The inconsistency of opinions regarding storage temperature is why I decided to do my own testing. Some people say there's no benefit to cooler temps, others do. Who are you gonna believe?
It's not the expense of batteries that worries me; it's availability. Most of the big-name manufacturers are trying hard to keep loose cells out of the channels that we buy them from. I don't want to be in a position a few years from now where I need some "fresh" ones and the only ones available to buy are re-wraps of uncertain quality. I'd rather stock up on known-good cells when they're available and determine the best way to store them.
So I guess the Chinese govt decided to lockdown parts of china due to covid outbreaks. I have not looked into it much, but I see that Fasttech is affected as well as Hiliq (they just send me a notice about it via email.

It might be even worse than that UncleJunkle. As of May 1st, all manufacturing and exporting of vape related devices may end coming from China.
