Here's what the battery guru had to say about that battery when he bench tested it.

I can't tell you if you should use it or not (I wouldn't), but after reading the results I most certainly wouldn't be building for high amperage.

https://www.google.ca/amp/s/amp.red.../imren_purple_40a_3000mah_18650_bench_retest/
And that was the particular cell that mooch tested at that time.
Who knows what is under the wrap now.

Only buy genuine batteries from reliable vendors.
LG HG2, VTC5A, Samsung 30q, etc
VTC5A is a decent choice for most mech useage.
25 amp rating at 2500 mah I think it is.

Battery Mooch is THE vaping battery expert that you can trust.
Check out his recommended batteries and test results here.
He also has recommended vendors where buying origional good batteries is often cheaper than buying iffy rewraps elsewhere.

We have some really knowledgeable people here when it comes to batteries. I had questions and they were answered in depth. With their helping hand i got bats that perform just as i want and to b honest better than i expected.

Mooch also has a series of very good instruction videos on youtube about vaping batteries and such.
https://www.youtube.com/channel/UCePHh3NMvu3rW2LFJeOWo-Q

Anyone using mechs should educate themselves on battery safety so they do not 'blow yer face off', or have a fire and bad burns.

imho if you cannot or will not educate yourself on using a mech safely you should not use one,
Kind of like giving a chainsaw to a child.

You asked about a battery for the mod. But that's not how it works. The battery for a mech is chosen by coil resistance or using a coil that's within the parameter of what the battery can do.
There are good battery brands and bad ones. IMREN is bad. I suggest not using a mech until you understand completely how to stay as safe as possible.

If you don't understand what truly can happen if bats r not properly used watch this video till the end of it.

I use the purple Imren 20amp 3000mah batteries in my Noisy Cricket and they really work nicely...just mind your build, know Ohm’s law, and you’ll be fine.

Since they are similarly priced, there is no reason to buy anything other than from a premium brand like
Samsung
Molicel
Sony
LG

Everything else is bought from them and wrapped with their own label and specs, not to mention the top 4 companies keep the premium lithium they produce, for themselves and their own brand. They'll keep the best of the batteries they make and sell the rest to a re-wrapper. For those reasons I only buy from the top 3 companies I listed.

I have watched a bunch of vids on the mech mods.I was trying to get a high amp battery to give myself a wider range for builds.

So long as the build you put in it are within its parameters

Ok Thanks
http://www.ohmslawcalculator.com/ohms-law-calculator

Put in the ohms of your coil
NOTE always check build on a regulated mod or ohm checker. with the atty fully assembled, becuase coil can short to chamber cover and such.

put in 4.2 volts for worst case current.
Your actual battery output voltage under heavy load will be more like 3.7-3.8 volts.
Battery output voltage drops under load. How much depends on the battery specs and how much load.

Hit calculate and you will see your amps required.

I have some Samsung 25R batteries ,is 20 amps good enough for a mech mod?
I use those in some of my mechs, but

Very good advice!

Coming on here and asking questions is a smart move by the OP, it still makes me nervous for people when I see basic battery questions. Mechs aren't anything to rush into, I'd consider my self an experienced user and still take great care and respect of what I'm using.

that vid posted by Wb80 is very comforting.
there was a ton of warning before the battery blew.

plenty of time to get it out of the house.

is there a quicker failure?

That was done with a lil wire. It can happen faster or slower.

anyone know what is average.?
i study mooch's stuff n i'm real careful.
any venting for me would be due to battery or regulated mod failure.
that's possible but i'd like to know how bad it might be.

There are too many variables to say what average would be. The one constant is heat. That's how you'd know something is about to get interesting real soon. If the battery is overheating you'd know it in most mods and can dump it.

thanks.
i'm not worried about things happening while i'm awake.
you hear about bad things happening in the middle of the night.
i know you can remove batteries, but i use 4 set ups all day n removing batteries is too much of a pain.

At minimum, turn the regulated mods off. I take the batteries out of my mechs at night.

Good battery hygiene (no tears, etc) will protect you, people that take care of their gear usually don't end up having issues.

Yuppers. Even then, things can go badly. Lock your mechs too...

I never have had a full thermal meltdown of a battery, but I have had one stuck on auto-fire in a mech once. It was a heavy solid copper Panzer mech with a AGA-T2 Genny on the top. My usual vape years ago. ;)

The thing was, the spring failed to support the weight of the full tank + battery + the weight of the mod and it auto-fired when set down.

Took about 2-3 seconds before I noticed it firing and by then the whole thing was too hot to touch. That's with a 1.1 ohm Kanthal and SS mesh build that got turned into a electric space heater real quick. Grabbed a towel, unscrewed the bottom cap to stop it firing, then ran the thing into the kitchen and dumped it in the porcelain-clad cast iron sink, towel and all.

Fortunately, all that happened was a scorched towel and a mess of boiled liquid.
The mod and atty are pretty much indestructible and using a SS wick, nothing to burn.

What saved me was the battery: a brand new (at the time) Samsung 25R that was way overkill for that tame build, but it took that torture and didn't even get damaged or swell at all. If I'd had a cheap efest or something in there, bad shit likely would have happened.

Ya, that spring got replaced with a much stiffer one! And, I always lock my mechs.

.34 is pretty high for a single 18650. For my way of vaping anyway.

I do .34 paralell SS316l coil on a Pico Squeeze. Single cell unreg squonk mod. 20 map 25R cells. Hits harder with a VTC5A though.
A nice warm vape. not hot but warm.
I use the same build in a Merlin RTA at 24-25W on a regulated mod and again a nice vape for me.

Regulated mod.I don't get my mech mod till tomorrow.I am going to use a Samsung 25r battery and it is only rated at 20 amps.This will be my first mech mod.

I've only got 20 amps to work with.
I don't want to hijack this as gsmit1 was about to give you solid advice, but I can tell you that running a dual coil rda on a single 18650 is not something I do simply because your going to feel the battery drop pretty quick. That's not to say you can't, I'm sure a lot of people do, just have spare charged batteries at hand. What mech mod will you be using? It's all about experimentation and finding what works best for you, just stay safe within your amp limits and enjoy!

With a 25R you should be abler to run up to around 75 watts or a bit more with no issues.
Build resistance is not as relevant on a regulated mod.

That would be a weak hitting and cool vape for me that's for sure.
Me too personally.

I think he meant what ohms and wattage do you use on a regulated?
Right. Trying to get a feel for what he's used to.Not to sound the wrong way, but I'm not sure if our friend knows exactly what he's getting into though.

I don't want to hijack this as gsmit1 was about to give you solid advice,...!
Oh no LOL! I appreciate the courtesy, but don't worry about me :) I've only been into mechs a few months myself. Like I say. Plenty of folks around here far better qualified to be giving advice like this. I was just trying to maybe help get him pointed in the right general direction.

Yeah, that might be the biggest difference between mechs and regulated devices. A regulated mod doesn't care about the resistance beyond what power requirement it's being asked for. The voltage regulator will manipulate what's available in the batteries in order to provide the wattage being asked for to the coils and will refuse to do so if any one of it's set safety parameters is being violated. (as long as it's working properly.)

Mechs don't do any of that and it's on the user to set his own parameters and know how to keep the current draw within the safe limit of whatever battery he's using. Of course you knew that, but I was just pointing it out for the edification of the OP.

And The mass of the coil is very relevant as to how hot it will run on a mech.
A 26 ga roundwire build will run hotter than a 24 ga build and both will run hotter than a Fused clapton.
More mass = longer warm up time and more area being cooled by the airflow.
A higher mass coil will also require more watts on a regulated mod.
And mesh is a very high mass coil. Just thought I would throw that in there ;)

Many factors involved and not as simple as I laid out though.
such as atty design, dual vs single or parallel coil, etc.

I got my mech mod today and it is working fine.Really like it.I have two 30A 2000mah Samsung batteries coming and I went by Moochs list of online stores to get them.

If you got the blue batteries I'm thinking of, that's the Samsung 20s which is a great choice. Those are indeed 30 legit amps and 2000 mah as per Moochs' testing. They will hit like a tank for a while, but at the cost of dropping off in performance quicker than some others. Make SURE you keep them charged well.

And especially with copper, you REALLY need to keep your contacts and all the inside very clean.

What is the resistance of the build you have in there again?

That is a Copper Onyx tube. I don't know if it's a clone or authentic. I don't recognize the RDA.

Its a .34 build,I got the mech mod on ebay for $11 and it has a magnetic switch also believe it or not the threads are really smooth.The tank is a Wotofo Freak Show 22mm which you can run in single coil also.

For single coils of that resistance I make a parallel wound 3mm id 26GA SS316l 10 wrap that come in at around .35 and vapes nice.

Well at that resistance, with pretty much any decent battery in decent shape, especially with a 20s, you'll certainly be safe as far as the batteries themselves are concerned.

That's a nice mod, probably even if it's a clone :) It's old, but I have old ones that are nice too as do many others here. I'm sure I speak for most everybody when I say I want you to enjoy it, If it seems like you're being babied, it's only because people want you to be safe. :shades:

It would be good to watch and absorb a bunch of Mooch's VIDEOS on mechs and battery safety along with SOME on the proper care and cleaning of mechanical tube mods. Yours isn't a hybrid (direct contact between the battery and the atomizer) so that does make it just a bit easier.

I think Cromwell's' vaping style is much closer to yours than mine and he certainly has a lot more experience than I do.
