Ok, let me explain a bit about how the battery industry works. There are only a few companies that actually make the Lithium Ion batteries. Keep in mind, they manufacture for all different types of devices like laptops, cars, cordless drills, etc. They sell some lithium ion batteries in form factors specifically for the device... like a cell phone. But they also sell batteries in standard sizes, and let the manufacturer do what they want with them. The battery companies call these "cells". Companies that make laptops, might take some of those batteries and soldier them together. The battery companies never do claim that these cells are end user batteries, and that they're intended for companies, and those companies take the liability for the safety.
Now, price is also an issue. so, they don't just make the top amperage, MaH batteries all the time, they offer other lower grade batteries for lower prices. Most lithium ion batteries run at a charge at 4.2 volts charged, and need to be recharged at around 3.4-3.6 volts. The mili amp rating is how long the battery will last before it needs a recharge.... With a bit of number fudging, this MaH rating can be highly subjective. So, you'll never quite get an accurate reading unless they are all performed under the same test circumstance... and that is what mooch did.
Also, as batteries discharge, they generate heat. If they discharge their energy too fast, the battery will heat up. If it gets too hot, the batteries might vent the gasses. They have done a lot to help with the venting, but there is still quite a danger. The companies then list a recommended amperage as a maximum discharge. Some even put a limiter, or a protective circuitry on it to prevent it from discharging too fast. This is usually added, and under the button top. They limit it quite low...
Now, that briefly covered amps, and Miliamp hours (MaH)... Some companies resell the original manufacturers batteries, and put their own name on it. Efest is one such company. Usually those sell to us consumers, but the truth is, you cannot be sure of what is under the wrapper. Also, re branding companies can also list their own specifications on the batteries. And since it is a very competitive market, they may run their tests to reflect a better battery than their competitors. That doesn't mean they lied, or they're doing anything illegal, but the numbers on their branding can be widely different than what the manufacturer recommends.
Now, that is where mooch came in. He took it upon himself to test as many batteries under the same circumstance so we can get an accurate assessment of how well the battery should be. Just so you know, NO battery can discharge at 40 amps without getting too hot. You said you've already looked at fakes... just keep that in mind. If I were you, I would choose from mooch's list...
Good decision.
We do not know the distribution channel these cells take before reaching their final retailer. Retailers cannot purchase these cells directly from the manufacture (or at least the non-rewrap companies) and must go through some sort of distribution. Despite regulations and a retailers reputation for selling authentic products, counterfeits can enter the distribution chain unknown to both the distributor and retailer. Even the trusted sources within Mooch’s list can acquire fake cells. Using trusted sources just mitigates that risk of receiving a fake cell.
Counterfeits are getting so good at disguising themselves; it is almost impossible to detect them by visuals alone. Legit companies can also change the appearance of their cells – LG is a good example of this where some cells came with a printed warning on the wrap and some did not. Does not make life easy for us. Even re-wraps can be counterfeited!
If asking questions on specific functions and or features for your device, probably best to open a new thread under that specific topic, ie: question about coils, under the “Drop In Coil” topic, or a question about temp control under the “Regulated Device” topic.
On a side note: These cells require a minimum voltage in order to stay operational. Exceeding that min voltage could lead to the degradation of the cells electrode - and if discharged too far, could render the cell unfunctional. To avoid this, regulated devices implement a safe cut off voltage which can vary depending on design – I have seen as low as 2.85 volts and as high as 3.5 volts. 3.2 volts is probably a comfortable average and well within the safe limits.
mAh ratings are usually achieved at a very low current draw, <1amp (I believe) and down to 2.5 or 2.8 volts. Not a true representation on how we use these cells but does somewhat give an indication on performance. That said, the higher the number does not necessary mean longer run time. A high mAh may discharge to 3.5 volts quicker than a low(er) mAh cell, but operates within 3.4 volts for a longer duration (as an example). If your device has a high cut off voltage (+3.4volts), you may not be benefiting from the higher mAh cell.
Should have linked this earlier. On top of Mooch’s YT channel, he also has a few running blogs within ECF. Some of the information is a bit dated, but pay attention to battery safety.
@Baditude also has a few very informed running blogs on batteries and chargers along with some general information on vaping.

I have the revenge x, I've had it now for 2 yrs. Great device. It holds up well! My old man works in a factory making tile and he's hard on stuff, period. Most mods I've bought him or he's bought himself be drops, they're done for!! I bought him the original Revenger long before I got the X and his still works great tti this day and is why I bought my X. We both love Vaporesso devices! And I personally love the fact the batteries have a magnetic door on one side verses a lot of other mods who have the hinged door on the bottom! I've learnt that all of our mods with hinged doors never make it past the 1st year! The door wears out and we're fix it and fix it and fix it until it can't be anymore. I've been looking into buying the Luxe, If you get it, lmk what you think?!
Thanks a lot everyone for such detailed info. You guys rock.
So I got my package of two VCT6 batteries and I bought them from a reputable seller. Since its the first time I am seeing these batteries. Please let me know if they are fine from the top? I see some space between the top terminal and black cover around. I attached the pictures. Also it says do not use outside the box. I didn't understand what does this mean. Please let me know.
Melanie, I didn't get my kit yet and this will be my first ever kit so I may like it anyways because not use to kits. But I will give you my opinion about it surely. According to my research the luxe S kit has the improved skrr S tank. But I will give you my opinion about it once test it for a couple of days.
