Hold on tight, you are about to get more info on batteries than you thought existed. I am not an expert on this topic, so I'll be watching this thread along with you.
@Baditude explains this very well
Efest, MOJO, AWT, Basen, Eizfan, IMRen, Sub-ohm Cell, Vamped, Vappower are all re-wrap resellers that are buying these "second and/or third tier cells" (sometime referred to as "B & C bin discards"). They print the "pulse discharge rating" on the label and pass it off as their CDR (continuous discharge rating). They often charge double what the authentic is worth. Unless you know what you are getting, stay away from these brands as you never know what is under the wrapper.

It should also be noted that there are many, many different models of Sony, Panasonic, LG etc 18650s. Not all are suitable for vaping, and of those suitable for vaping different specs make them ideal for different types of use (e.g. high wattage but low runtime vs lower wattage but longer runtime).

So who makes who's batteries? Who are the main battery suppliers to all of these other companies? Does Efest make their own batteries or are they rebrands as well? Would love to know more about the batteries I'm using and batteries I'm looking at purchasing in the future.
You're asking for battery industry top secret information.
We know for sure that LG, Panasonic, Samsung, and Sony make their own cells. You can't go wrong buying these batteries.
Everyone else, its anybody's guess. But more than likely most of the other "manufacturers" are re-wrapping the second/third bin (rejects) of the above manufacturers. They buy them cheap and sell them for a lot more for a hefty profit margin after putting on a new wrap. They usually advertise inflated battery specs, too.
Andrew Wan from AW was a former employee of Panasonic, who branched out on his own and allegedly has agreements with the main Japanese manufacturers to buy their first bin batteries and sell them under his own brand name. Others believe he makes his own IMR batteries in China. He was the first to bring an IMR battery onto the market, and is the only top manufacturer to sell IMR batteries in the 18490 and 18350 size (while LG, Panasonic, Samsung, and Sony do not make this size).
Efest claims they make their own batteries, but bench tests prove in my mind and others that they are selling re-wraps of other brands. They also over-rate their battery specs.

As stated previously LG, Panasonic, Samsung, Sony (and possibly AW) make their own cells. These are recognized as the industry leaders in the battery trade. They don't over-rate their battery specs. However, not all batteries are created equal. They go through a quality control process before they leave the factory. The lesser quality cells (known as second or third bin batteries) get sold to other companies to be rewrapped under a different brand.
Most other brands will buy the lesser quality batteries from above for a cheap price and put their own brand wrap on the cells. Many also deceptively "over-rate" the specifications in order to compete with the major brand companies. What's bad about this is consumers might have a false sense of security (safety) using an over-rated battery.
Purple Efest Batteries Not As Advertised
Imren Purple 40a 2500mah 18650 bench test results; only a 20a battery, runs very hot
Battery pulse ratings are useless! | E-Cigarette Forum

Somewhere in the product description page the battery specification sheet should be displayed. The most important specs are the "maximum continuous discharge rate" which is the battery's amp limit, and then the "capacity" (or mAh) rating.
Guide to Battery Specification Terms:
Batteries can generally be broken down by two major characteristics: capacity (mah rating) and amps (current handling). When choosing which battery to buy you must pick which characteristic is your priority for the application that you will use it. You can't have both the highest mah and highest amps in one battery. This is due to the limits of current battery chemistry & technology. Safety should always be your number one priority.
Capacity or mAh Rating - an approximation for how long a battery charge should last from 100% charge to when the battery will cut off. Roughly, 100 mAh = 1 hour usage with low drain applications like a flashlight.
The "best battery" is not always the one with the largest mAh rating. In most vaping applications a higher amp rating (CDR or continuous discharge rate) determines the better battery.
Amp Rating - or "continuous discharge rate" (CDR), is the maximum electrical current at which the battery can be discharged continuously before the battery will fail. This specification is set by the manufacturer, and is a standard measurement in the industry. The "pulse or burst discharge rate" is not a standard measurement and varies from one manufacturer/vendor to another making comparisons from company to company impossible, and therefore should never be relied upon.
Sony US18650VTC4 2100mAh 30 amp battery.
Specifications:
Nominal Capacity: 2000 mAh
Typical Capacity: 2100 mAh
Nominal Voltage: 3.6V
Discharge End Voltage: 2.5V
Standard Charging Current: 1.5A
Charging Voltage: 4.20+-0.05V
Max. Continuous Discharging Current: 30A
Internal Resistance: 12 milli-ohms
Dimensions: 65.00mm (L) x 18.20 mm (D)
The Sony VTC4 battery has the most amps and mAh combined, comparatively to other brands and models.

I'd stay away from "SUMSONG".
That'd be like getting a burger at "McRondalds" or a watch from "Bolex".

Authentic HE4, LG HE2, and LG H2 18650's are much easier to find. Sony VTC5's are so rare it's not worth risking unauthenticity. VTC4's are much more likely to be real because production is greater of these, plus they have 2100mah and more than sufficient amperage for 200W TC Box Mods like the Snow Wolf 200W 1.5 Limited Edition TC or Sigelei FUCHAI 200W boxes. The FUCHAI box sometimes is sold with Sigelei batteries but those suck. For the cheap new Sigelei 200W mod (which blows away the 150W that so many adore and spent 35 bucks more on), get LG HE4's at the most mah you can find or LG HE2's. The Snow Wolf isn't technically 200W without a pulse feature which sucks down half a pair of batteries during high wattage vape hits then the batteries return to full voltage. So perhaps skip Snow Wolf mods until version 2 in February. The 69.99 or, 54.99 on some good sites, is real ergonomic and feels good in the hand like the 150W did...metal and rubberish construction or it seems plus plastic obviously in places like battery hatch, all mods though. Get that unless you can afford a Vapor Shark DNA 200 with additional zip charger, hard shell casing accessory, 250 bucks total and a Windows PC. Otherwise wait for the Sigelei 200W TC Box Mod with the color screen for 129.99 coming out in about month. Use a pair REALLY good batteries for the colir screen reasons on the upcoming model. But my FUCHAI Sigelei VW/TC 200W BOX MOD is the best investment I've made. Not too small, not very heavy but sturdy enough so not to feel cheap, very easy chip/menu management and no firmware updates. Hcigar VT200's are known to crap out and have difficult 510 threading. And DNA mods are basically over-rated junk with most often low mah internal batteries unless you mess with them and modify the insides. External Battery boxes of good quality that require only 2 batteries are harder to come by since the DNA 200 crap came out. My Sigelei doesn't need any "customized to my liking" gimmick. It's perfect if you like the design. Anyway, LG H-series 18650's, perhaps Samsung INR18650-25R 18650 2500mAh 3.6v (ask around here about their safety if they're all real), or authentic Sony VTC4's are best. I want to risk authenticity and order Sony batteries because nobody anywhere has said real VTC4's are not fantastic. LG HE2 or HE4 batteries with the highest amperage are a good secure choice plus they have models with high mah aka battery life
Sony, Samsung, Panasonic are real-famous-battery brands. The others are re-wrap batteries
Yeah I decided on 2 Sony VTC4's in a Sigelei FUCHAI 200W box mod black with the included silicone sleeve. 59.99 on vaperoyalty.com. I think that'll pump up watt mode to 195 or so charged up, VTC4's. I'm sick of my full size TFV4. I TRIED all coils and just am ready to try the old Triton .4ohm coils. 19.99 plus 17.99 5 pack of coils. I can deal with top filling leaks. I know tricks. Not filling high in tank, high VG, regardless of recommendations, etc.
10 bucks is the cheapest I saw real VTC4's online. So 20 extra damn bucks. I don't want the Reuleaux because the Sigelei will be just as it should be, no problemo. I can get it up to the full 200W on VW mode. I don't do TC ever. It's too hot for my lungs. I've smoked since 11 so. Lol
What does DNA200 vs Sigelei, the TFV4 and the cost of coils have anything to do with the difference between battery brands?
