Same here, ordered them from Fast-tech, so it's taking awhile to get to me. But so far these batteries have powered my UDC Trident like a champ. Got the nitecore charger as well. Hope it lasts longer than the Trustfire charger that I originally had

They've started weaning them out for the more cost effective 2000mah version. Most users won't have a problem with that, but us vapors that do sub ohms have to start looking for alternatives. That was an amazing battery and lighthound sent me notice the other day they'll still have supplies for a while but no new ones are being made. I try to think ahead so I'm looking for a good battery now rather than later.
Be sure to get unprotected batteries. I mean, you can put a protected 18650 in the battery compartment - but the door won't close because of the added length.
The term "unprotected" when describing batteries is a pet peeve of mine. The correct term is "IMR". Safe chemistry. High drain. Lithium Magenese (Li-Mn).
Unprotected can also mean a unprotected NCR/ICR li-ion battery which is an entirely different Li Ion battery chemistry. Unprotected li-ion batteries should NEVER be used in a mod due to their inherent unsafe battery chemistry without protective circuits.

I use the samsung 20r batteries. I build around 0.4 ohms on my patriot and these batteries perform well.
I would highly recommend the Nitecore 18650s and chargers. Nitecore makes tactical and emergency flashlights, and those really aren't useful at all without a decent battery.
Same with vaping equipment though, right?

Actually, a "protected" battery means it has an IC (integrated circuit) which protects the battery from over charging, over discharging, and too much current. The battery actually has a little circuit board attached to it under the shrink wrap.
I have the VTR and really like my Panasonic NCR18650B 3400mAh batteries for it. Super long vape time, and super stable chemistry. And since you are using a regulated device, you don't need (nor should you use) a protected battery. The VTR will handle the protection.
I'm going to have to try the Panasonics. This Efest is ok but I vape pretty much constantly and I've never run the VTR down to the red indicator but I usually put it on the charger in the evening and use my Evod for a couple hours while it charges. I just need to buy a spare battery. Spent all my cig money on gear and juice til next month. I've got Li-Poly's for my Planes that will put out 60 amps... Could build a hell of a coil for those...lol! I can charge those in 10min. I'm not sure how fast you can charge Li-mn batts?
I have a pair of those and have used them only sparingly while my other batteries were charging. I don't use them regularly because I suspect that they're unprotected ICR cells, but I can't confirm this because I haven't been able to find the specifications for this particular cell. The reason I suspect ICR chemistry is the nominal capacity of 3400mAh. Unless battery manufacturing has made a tremendous advance, I don't think it's possible to achieve such a high capacity with IMR or hybrid chemistries.

These are not high drain batteries, so they are not optimized for use in regulated mods, or mechanical mods using a Kick module, or with RBA/RDA's.

That's what I suspect as well, but others on this forum believe that the new NCR chemistry is safer even than the IMR chemistry. Panasonic doesn't publish the max current rating on these, so there's no way of telling if they're high drain or not. However, I have seen them tested as high as 5.0a, which is the limit of the Vamo and most other regulated mods (ProVari is 3.5a, IIRC) and the batteries performed very well.
Test of Panasonic NCR18650B 3400mAh (Green)
If I'm doing the math right on the energy density from Panny's specs and the test results shown above, the max discharge rate would be ~7.0a which is within the limits of anything I'd be dropping one of these cells into.
However, I'm always in belt-and-suspenders when it comes to battery safety so I'm hesitant to use these on a regular basis. The high capacity and high computed amperage make them fine for short term, light duty use. But I wouldn't put them in a mech or kick it with any device capable of exceeding the computed limit.
I sure wish I could get my hands on the factory specs showing the discharge rate. Panasonic makes quality batteries and I really would like to use these.
The continuous discharge rate is 6.8 amps. I couldn't find this on Orbtonic's or RTD's website, but I do recall reading it somewhere. Possibly PBusardo's Taste Your Juice article on batteries (?). I've seen Thrasher quote that specification, too, and I have no reason not to trust what he says.

...!?! Only 0.2C for the NCR19650B!!! I thought they were at least 2C. At 0.2C, that's only .68 Amps discharge rate! I gotta get some of those AW IMR batteries!
That's what I calculated too, using a 2C rating that I'd seen elsewhere on another vendor's website. With a nominal capacity of ~3400mAh and 2C rating, max discharge is 6.8a.
No way those are genuine Panasonic NCR's. The energy density ratings are way too low. Those are either counterfeits, or factory QC rejects.
It's the Wild Wild West in the battery market.
Edit to add: If those batteries actually had a 0.2C rating, they would have vented during HKJ's testing.
