Depends on what OHM rate you build the coil to. A 1.5ohm coil runs at 9-11watts, 1 ohm coil will run at 13-17watts and .5ohm coil at 27-35watts and a .2ohm coil at 68-88watts. BUT the .2 coil will also run at 22amps which is beyiond the safe limit of a 25R battery.
This should help, Battery drain

Without reading any article common sense will say it depends on the resistance of your coil and the power loss of all your connections. Some mods and atty's are more conductive ans some are less. The lower your resistance is, less power you are getting from the battery due to battery sag and conductivity problems.
The wattage drawn from a battery depends on the load you give it.
A fully charged lithium battery is 4.2 volts.
If you put a 1 ohm load, your wattage will be 4.2 x 4.2 / 1 = 18 watts.
If it is a regulated mod, the mod electronics attempts to draw the power that you set.
If it is a dual battery mod, more power can be drawn from 2 batteries than from one.
Same ohm rate in series would be the following wattages, 1.5ohm= 36-47, 1ohm = 54-70, .5ohm 109-141 and the .2 = 273-352 watts. BUT the .2 would be at 42amps and unsafe. Lowest you could technically do with the 25r would be about .42ohm and 130-168 watts Battery drain
Sorry to be a little rude, but if you don't know how to calculate these results, then don't use mechs and stay at regulateds...
The calcuations done by several above are correct, although they are theoretical, meaning no voltage-drop of mod and no IR of battery. You will never achieve the results quoted above...
A series mech, in dual-config, gives double the voltage and e.g. a 0.8 build is the same as a 0.2 build on a single cell-mech. A dual-parallel mech will not give that much more power, but since the IR is split between them, then at lower ohm levels, there will be some difference and that gets hightened upon how many cells in parallel e.g. tripple-parallel etc.
The samsung 25r is a 20a CDR cell, so just use an ohm's law calculator and see what's possibly under safe meassures i.e. at 0.25 or above... Well, it has already been stated above how many watts, but again, these are not true obtainable values...
Also, a hybrid, i'm guessing you're referring to a pinless-510 mod, and they can or can-not give lower VD, depending on how it's made totally, and if it helps, then it's only very little and not something to be felt unless if using pretty low ohms...

Ohm rate?
"Resistance" is the word you are looking for.
Yeah, Yeah.... You, use your big words, I'll use my small words. Meaning is the same.
You don't need to do the math yourself or even know how to do it. There are plenty of good tested Coil calculators out there. I like Steam-engine.org the best but Coiltool is also good for quick simple builds. Those, a good Multi meter and a 510ohm/volt meter, plus enough common sense to USE the tools, and try to understand them. You can do allot of building and stay very safe. Goal is to stay within all the safe limits of every bit of your vaping equipment.
Thank you for the information guys this was really helpful since I was deciding whether or not I should switch from a mech to a vw mod.
A lot of the problems with regard to safety we have in vaping have come about as the result of complacency and a general dumbing down of the community at large. Part of the process includes the misuse of terminology and the unwillingness to learn and understand the fundamentals of circuit theory as they apply to our purposes. Placing 400 watts under load up to your face without understanding what it is you're actually doing and the inhearent danger of doing so is a recipe for disaster and flat out irresponsible.
If only the offender was held accountable in the court of public opinion, I could care less. Chalk it up to natural selection. However, as all users of e-cigs are clumped into one collective pile for judgement, I must take issue with your position in respect of my own interests.
To advocate ignorance is a foolish position to take at a time when the future of vaping is being decided by people who use this very ignorance as their preeminent tool in imposing regulation on us in support of their friends in the tobacco industry.
Also, if you super sub-ohm, you need to know resistance values to the one hundredth of a ohm. What multimeter do you know of that reads to the one hundredth of an ohm? I have a pretty top notch Fluke, but I don't know of any Fluke product (with the exception of their bench testers) that read resistance units beyond a tenth of an ohm. Even coupled with all of the common sense in the world, a good multimeter will not help you determine your resistance to a one hundredth of an ohm. Unless you do so via calculation using you multimeter to measure current. But that would require knowledge of Ohm's Law
.Knowing or using the proper names for things does NOT make one safe.
Plenty of people out there driving cars. That don't have the faintest clue of how turning a key makes 4000lbs of metal and plastic go. Yet they are safe.
Yes, people should educate themselves on safety involved with vaping especially on the DIY aspects. That does not mean they have to learn all the science or math. They just have to know it is there, respect it and use it.

I think the issue is that when it comes to safety and mech's, there isn't actually that much you really need to know to keep you safe. There is a lot to know to get good performance, but a small amount of basic knowledge can keep a user safe.
Not knowing the word "resistance" shows there is potentially a hole in the knowledge base. With vaping, it's a ridiculously common word. I certainly wouldn't call it a "big word".

I agree that it's not a big word by far, but come on guys, it was a slip-up probably, like e.g. myself in a previous post here where I wrote "... at lower ohm levels" We shouldn't advocate ignorance, obviously, but also we don't need to be word-nazi's either... It's not factually correct, but the meaning is the same, in contrary to e.g. the hybrid vs pinless-510 debacle...

While I agree with you mhertz (we all have a brain fart now and then) my post was because resistance was being regarded as a "big word". Resistance is not a big word when it comes to mech's.

He made up a term instead of using the correct word "resistance", while giving battery safety advice.
Pointing that out is not being a word nazi, it's being safe.
Please don't condone this.
This is one reason why new vapers have problems understanding what they are doing.
I know you guys will correct me if I'm wrong but here I go anyway to show that not consistantly using the same/proper terms really can hurt! Because I try to understand what what I'm doing I did understand the terms used above correct or not! The statement that confused me was this;
I have always used vv/vw gear for the year I've vaping & never understood the use of mechs at all! But recently I've been looking into squonking & getting something like a REO! Because of this I've been looking into mech mods & their SAFE operation! What I learned here on ECF is the RESISTANCE (OHMS) is probably the BIGGEST word in safety because it's the only way to determine what the amp draw you're batteries are getting & without knowing that you run the risk of the mech blowing up! So if it is true that resistance is not a "BIG WORD" when it comes mechs What is?
Yes, it's one of the biggest words, but i'm sure 93gc40 didn't meant it like that, as he's not ignorant.
As said, when I said "blah blah, at lower ohm levels", then that's wrong and I will not do it again, but I fail to see it has anything to do with "mis-safety", as everyone knows what is ment... Pointing things out that's obvious is the usual definition of a word-nazi... If it was expressed in any unsafe manner, then different of course, eg. as I stated before about the hybrid vs pinless-510 mods, which is another case entirely...
Anyway, I agree that we should use proper terminology as best possible, especially when safety is concerned
Mech mods are for advanced users, or rather advanced readers, lol Ohms law is mandatory anyways...

You have misunderstood what I was saying. My point is that when it comes to mech's, resistance shouldn't be a "big word" it should be a word used all the time to determine safety.
