How are you going to stuff 21700 cells into a device that takes 18650's?

You need to forget about 97% of what that vape shop told you, they flat out lied or at least misrepresented everything to make a sale, there is an outside chance they actually believe what they said, in that case I'd avoid further contact.


Brown, green whatever is not a way to properly identify any cell used in vaping.

We would need to know, actually you would need to know, the exact brand name, model, series / any numbers & letters on wrap to identify the cell which then could be used to determine mah, CDR / overall quality.
Of course buying only from reputable dealers/vendors is the only way to ensure you don't end up with counterfeit name brand, or lesser quality rewrapped cells.

Again, beginning basics, battery safety & selection.

Won't fit your mod. Though those are very excellent batteries, I use them in my 21700 squonk mods.

It seems you are hung up on maxing out power. Is there a reason why you are doing this? Again, I run at 45-50w on a single coil and pump out just as much, and sometimes more, vapor than the guys i run into trying to flex their vape muscles and run super high watts on super low ohms. I just get much better battery life. Try different set ups and don't get all hung up on the false assumptions that bigger (or more power) is better. A lot of the time the peoplei see try lower power vaping, enjoy it more than high power.

Yes, I know what they sold you, I got it the first time you mentioned them.
In reality there is no way to determine what cell is actually being used under the wrap.

That isn't the issue with the cells you linked.

If I get a 30 amp battery what shud the mah be?

Okay and I get you were given a lot of misinformation. We all have some, some of the time.

But the POINT of this board is so that you can ask your questions and get accurate information.

I ONLY buy batteries from Mooch's list of recommended vendors, I would trust a vape shop to supply me batteries about as far as I could THROW that vape shop, so 0%.

You ALSO need to look at Mooch's blog there is a chart in there that tells you the testing he has done on vape batteries, and also what rating they are REALLY okay to run under.

It is not okay to abuse your batteries or your equipment . Expecting TOO MUCH and demanding it from a subpar battery is vaping abuse. Vaping abuse can lead to severe CONSEQUENCES like your mod Blowing Up.

I get annoyed when that happens, and yes I have some sympathy for the vaper it happens to UNLESS they were given the correct information and chose to ignore it. I then get vaping annoyance for the few and highly touted who DO blow up their equipment and claim they didn't know when they were told. Repeatedly. Because, we have the kind of media who will report on "how unsafe vaping is," rather than the UNSAFE PRACTICE the vaper was engaging in.

Don't use those batteries. Recycle them. You have already overstressed them and you have no idea what they actually are, they could be both poor batteries for your application AND REWRAPS for all you know. Those could be 10 amp cells, for all you know.

Read Mooch's AND Baditude's blogs.

https://www.e-cigarette-forum.com/blogs/mooch.256958/

https://www.e-cigarette-forum.com/blog-entry/baditudes-blogs.7609/

There's another set of links.

And by the way, I'm glad you are asking questions but you have so many questions in so many different areas of the board, *I* am getting confused and so that means you probably are too.

Slow down. Do some remedial reading on vape safety and vaping generally. Give yourself time to absorb it.

You do not want to be "that" vaper. I mean it. You don't.

If you want a 30a CDR cell pick one from Mooch's list, there aren't many options of mah with a true 30a CDR cell, most are fairly low.

I'd use a 25a CDR cell & learn to build a more efficient set up instead of use the get a bigger hammer method.

Actually I'd use quality 15a - 20a CDR cells and build an efficient setup that would function tremendously & never come close to the cells CDR.
Mostly so I could take advantage of increased run time due to increased mah & lower CDR requirements.

First step, understand the cell size differences 21700, 20700, 26650, 18650 are all different actual sizes. Different lengths & widths.

If you don't understand size difference, mah, CDR, you really should put down that hexoxhm until you understand the very beginning basics.

You won't find a 30 amp continuous discharge rated battery with more than 1500 mAh. With higher amp ratings, you sacrifice mAh capacity. You can't have both a high amp rating and a high mAh rating. That's how it works.

** I haven't seen it available yet, but Samsung should have a 2000 mAh 30 amp battery sometime in the future.

Yeah, the charge on a 1500 mah battery won't last long at the voltages you are currently using. That's the sacrifice you pay for using such high voltages.

You could drop your coil resistance to a more reasonable 0.6 ohms and use a 25 amp battery that will have more mAh.

You don't NEED it, you only need it if you WANT to vape the highest power possible. If your batteries are a) genuine, not fakes and b) you know their REAL amperage, whatever it is, you can safely vape UP TO THE RECOMMENDED POWER LEVEL FOR THAT BATTERY.

You could have a 50A battery, say a car battery, and if it didn't fit in your mod, it would be useless to you. If you want to use that mod, get the highest rated 18650 and then check out Baditude's chart as far as HOW much wattage you can expect to safely output, PER battery.

Also, amperage usually sacrifices runtime, so you are going to have to make your best choice you can on that. Some batteries do better than others, but as a general rule, capacity is sacrificed for longevity.

Stop trying to obtain the highest power, just because. One of my mods is currently set to an all powerful 8.4 watts, so I PERSONALLY think you have plenty of wattage "wiggle room" to play with without turning up your speakers to 11, when they only go up to `10.

Would you assume that habitually driving your car at it's maximum speedometer reading would be a safe practice, even if in "theory" it "can" do that?

Can and should are very different words, with very different expectations and you should make the jump from "can" to "should" and begin vaping safely.

You misunderstand. To get the full 180w, you would need 30a. But if you don't use it at full power, then lower amp, higher mah would be fine.

You also seem to avoid my questions to you, which is quite disrespectful since I have been nothing short of nice to you, and not just rip on you for not doing research and educating yourself before buying an advanced level mod.

Well here we go.

The hexoxhm v3 is a series box, even with its 'proprietary board' it draws from both cells as if they were stacked.
Meaning the two cell increase voltage but the safe amp rate/draw is that of 1 (one) cell.

It does not have an actual over current hard limit / reliable over current protection. Most times the board will refuse to fire but not always, sometimes the board or mosfet will hum, squeal / make a noise but still fire in an over current situation.
The potentiometer is a crude voltage adjustment, it is not at all like a regulated Variable Wattage device.


The protections are just enough to allow experienced advanced users some marginal leeway when experimenting beyond what would be considered normal safe vaping practices.

Nothing I would rely on to prevent something really bad happening, even more so when using unknown quality rewrapped or insufficient CDR cells.
It is certainly not a beginners device or something to learn on.

A series circuit creates a current from each battery at the same time and combines the voltage from each battery. While the voltage is multiplied by the number of batteries, the amp draw and mAh remains at that of a single battery.

A parallel circuit splits the current between two batteries at the same time. While the total voltage remains that of a single battery (4.2v), the total battery life (or mAh rating) is increased as well as the overall amperage..

MVS listed the Samsung 20S this morning for $6.99 each.

Samsung INR18650-20S 2000mAh Battery - 30 Amp

I have no use for a 30A battery. A high capacity 15-20A battery is more along my needs.

EDIT: I do agree with the other numerous post here though. It seems like you are trying to find the biggest/most powerful setup you can, and that's not what it's about. Find something that vapes good for YOU. I second the comments above about finding a good 20-25A battery and a build that works well for you within those limits.

Then you get a great vape on higher capacity (2500-3000mah) cells.

Yes I know, I made a mistake, thanks for pointing it out so I could correct it. :thumb:
