There are several good quality batteries to choose from.
the 20a Samsung is a good battery
the 30a AW is a good battery
the VTC-3,4&5s are good batteries
the NMKE is a good battery
Where you buy your batteries is more important than which of those quality batteries you choose to use.

I think that Efest must have tested the batteries at 35A and discarded the ones that don't qualify before putting a 35A label on them. As I mentioned, these batteries are being used sub-ohm, have not exploded, and do not get hot. IME, they are working great and last for a long time.
On any MOD, you have to Make Sure that Whatever Battery you buy is going to fit in your Mod.
So there may be a 10,000mah 18650 200A Battery out there that people say is the "Best". But if it Doesn't fit in your MOD, it Really Doesn't Matter.
ETA: What is the Longest 18650 Battery that will work in a Cloupor T5 and start from there.
18650 at any mah is the same size is it not??

No, that is not what they did.
They took a LG18650HE2 2500mAh 20A (continuous) battery and rewrapped them with their logo and slapped a 35A rating on it. What they did not tell consumers was that the 35A rating was the "pulse" amp, not the continuous amp. Their labeling on this battery is very misleading.
People around here seem to like the authentic Sony batteries, but I'm a newbie, so I'm not speaking from personal experience
Definitely one 18650. Stacking Li batteries is a no-no.
stacking in mechs is not advisable.... but stacking 350's in a regulated is ok... just make sure the regulated mods instructions say its okay... SVD and Vamo3 sez its good to go...
You are basing your opinion on a lack of evidence and purely on your own personal speculation and experience.
There is evidence from a reputable independent tester that Efest rewraps the LG 18650HE2 battery (which LG says is only 20 amp continuous), but puts the pulse rating (35 amps) on the purple label.
Other manufacturers use the continuous discharge rating for their batteries as this is the industry standard to indicate how hard a battery can be pushed before failure. There is no industry standard defining a pulse rating, its whatever a manufacturer or reseller decides to use. IMHO, this is intentionally deceptive on Efest's part. People are buying that battery believing it is a 35 amp battery and its not, its a 20 amp battery. There's a big difference between 20 amps and 35 amps. A big difference between continuous amps and pulse amps.
Efest makes another purple battery, a 3100 mAh model they advertise as a 20 amp battery. It is a re-wrapped Panasonic NCR18650BE model that Panasonic says is only a 6 amp continuous discharge rated battery. http://www.e-cigarette-forum.com/forum/batteries-chargers/587759-purple-efest-18650-battery-warning.html
Which would be why we shouldn't rely on any pulse rating from any manufacturer or vendor. Pulse ratings are unreliable. Any failure, mechanical or electronic, that fires the mod will operate in the 'continuous' mode. If your setup relies on a pulse rating, it's instantly over spec.
If your amp draw is safely under the continuous discharge range, your coil could act almost like a fuse and burn out before the battery is stressed. If you are running the battery at the edge of it's limits (the pulse rating), there is no margin of safety. Doesn't this make better sense from a safety perspective?

18650 30 amp continuous, IMR high drain battery. PERIOD...
edit: Far as efest goes, the owner of the new vape shop in my town told me, the efest has been bought out by another company in the last year, and are trying desperately to get on top and loose the bad mislabeled reputation.
You'll notice now on all the new Efest Purple products, they now list the continuous and max amp limit, and are looking more true to form. And their new chargers are much better. The usb port actually works without having batts in any slots, and much better engineered.
So yeah, am sure there is still some old stock by the old Efest, but the new stuff should be up to specs. I joked with the guy, they should of renamed the company "Not Efest",
Of course, this is unverified info, so shame on me, haven't searched it out, since am not in the immediate need for batts or chargers, and am waiting till the new chemistry high drain batts hit the market. But the links and info he showed me looked legit.

Stacking batteries in series only doubles voltage. The mAh capacity and amp rating remains as if there was only a single 18350 battery being used.
Two 18350 batteries stacked in series, each with 4.2 volts, 700 mah, and 6 amps will provide 8.4 volts, 700 mAh, and 6 amps.
There is no rational or practical reason today to stack batteries. There are more rational and safer ways to increase voltage (ie variable voltage regulated mod, variable wattage DNA mod, a Kick in a mechanical mod).

This is My Thinking.
Stacking Batteries seems to be a Hold-Over from the Past. When Increasing Voltage wasn't as Easy as it is Today.
Also, don't the Stacked Batteries have to have Very Similar Performance to Work Safely. ie: If one of the Batteries in the Stack is Under Performing with respect to the Other Battery, isn't this a Problem?
If you are running a DNA or sub-ohm build in a mechanical, yes I agree.
If you are running factory built or standard resistance coils (ie clearomizer, cartomizer, Kayfun-style RBA), no I disagree. All those amps in the Sony would be overkill, and there are 7 and 10 amp batteries with far more mAh for longer battery time than the Sony's.
Panasonic and Orbtronic NCR18650A 3100 mah 6.8A
Panasonic and Orbtonic NCR18650B 3400 mAh 6.8A
Panasonic and Orbtronic NCR18650BD 3200mAh 10A
Panasonic and Orbtronic NCR18650PF 2900mAh 10A
Panasonic and Orbtronic NCR18650PD 2900mAh 10A
Choose batteries based on their specs (amps and mAh capacity) according to the application they will be used.

You are correct. Should someone decide to stack batteries (against most people's better advice), they have to use new, identically-matched batteries and mark them as paired for life, the order that they are placed in the mod must be alternated each time they are discharged, and the voltage be checked coming out of the mod and off of the charger to insure they remain identical for the entire time they are used. If this practice is not done, one of the batteries weakens and becomes a weak link in the setup and will be more likely to fail. Once one battery fails, the other is likely to fail too. Then you have two batteries failing in either your mod or charger.
I keep pretty up on battery information, and I've never heard of that story. I sure would like to get my hands on those links.18650 30 amp continuous, IMR high drain battery. PERIOD...

I read a recent email response from an Efest representative that stated that all Efest batteries are made "by the parent company". Well, that's a corporate lie as I know of at least three of the purple batteries that are re-wrapped Sony's, LG's, or Panasonics.
"Made" is a Funny word when it comes to Many Products.
I can take other peoples Cells and Shrink my Wrappers on them and then say that I am "Making" a Battery. Whereas Most People would consider who Manufactured the Actual Cell as the one who "Made" the Battery.
Kinda a Symantec thing I guess.
But as I understand it. Efest does Not Physically Manufacture any Battery Cells. Only Wraps someone's Else's Cells. Just like AW does.
Something that I've always wondered about:
The ICR version of AW batteries say on the label, "Batteries made in China, IC and cell made in Japan."
The IMR version of AW batteries say only, "Made in China".
I also find it odd that many of the supposed sources of AW batteries (Panasonic & Samsung) do not market/sell batteries in 18350 or 18490 size, but AW does.
