Series mech mod
Just got myself a series mech mod and I need some advice on coils.
I usually vape around the 60 watt mark @ 0.2 ohms and I tried that with one of my "One" RTA'S and all it did was burn up the cotton...q
What prebuilt coil would give me the same type of vape that I'm used to ??
Insert smart and witty comment here.....

A "series" mod sends a LOT of power through, so you will want to raise your coil resistance to counteract that. Keep in mind, even at the .35-.4 that most agree is "optimal" for a series mod, it can STILL knock your socks off!

Definitely don't use nic salts/high nic juice!

Start with double your normal resistance, so roughly a .4. That should give you a very accurate indicator of whether Series vaping is for you. I don't recommend ANY single coil atomizer...Series is a dual coil thing!

When it comes to series mods you have to QUADRUPLE the resistance to get the same wattage vape.

If you use ohms law with 4.2 Volts and 0.20 Ohms resistance you will theoretically pull 21 Amps from your batteries. Multiply 21 Amps x 4.2V will give a theoretical 88 Watts. Of course battery sag and voltage drop will take their toll and in reality you'll get something in the mid to high 70s range when the batteries are fully charged.

If you do the same with 8.4V and 0.4 ohms you will still be pulling 21 Amps, but when you multiply the Amps by the Voltage to get a Wattage figure you multiply by 8.4 instead of 4.2 - this gives a theoretical 176 watts, even with battery sag and voltage drop that still is going to be around 160.

Personally I would forget pre-made series coils as they tend to cater for high wattage only, you could use dual 26 gauge single claptons, but you will have to use a lot of wraps to get anywhere near a 0.80 build - and they may be a bit much for an enclosed RTA deck.

Personally I would stick to dual coil RDAs with plenty of airflow and the ability to take wide coils, but don't forget to QUADRUPLE the resistance for the same wattage vape, if you feel you need more power it is easy to knock off a wrap or two - there will still be plenty of coil to cotton contact.

I suggest you try dual 10 wrap 3.5mm i.d. claptons in an RDA and work it out if you need more or less wattage from there.

Seems to me an easier, correct way to obtain a .4 is to install two .8 coils. Voila! A series build!

Watts are irrelevant on a mech. They don't make "series" regulated mods. Just build, or buy, a couple .8 coils. Simple.

Honestly, i never use a rta on a series. A good airy 24 mm rda, type Dead Rabbit, Kali v2, Apocalypse, Redemption at 0.4 as lowest is what works for me. And on a series, i always use lg hb1 or hb6 (30amp) batteries.

I think I heard him mention it being a dual 21700 series recently, so he's got the goods, lol!...and a Fatality style RTA will work just fine, mucho airflow is needed! RDAs are a natural choice, but not the only choice.

Its late in EU, but:
W = U x I
I = U / R
W = U x U/R, = (4V x 4V) / by 0.2 Ohms = 80 Watts.
You run your existing mod with 80 Watts and not with 60 Watts.
Is that right?

To run batteries in series is an other story,
depends the coils are in series or parallel or single.

Add Edit: e.g. a single coil with series batteries for 80 Watts:
80W = 8V x I
I = 80W/8V = 10 Amps
R = U/I = 8V/10A = 0.8 Ohms for a single coil.

Some of you REALLY don't know what a series build is, huh? Okay, for the few of you copy/pasting, save your time. A "series" build is simply a build that works well in a series mech configuration. That's it. No math, no computations, nothing special needed.

Most vapers agree that anything below .35 is simply too harsh, and too "rowdy" to be enjoyable when batteries are run in series, so .35 has become the "default" minimum for Cloud blowing mech series vapers...for as long as I've been vaping.

Most tend to err on the side of comfort, so I tend to use .4 as my standard. But anyone who's ever vaped series mechs , like Philip, or me, know that already, and want OP to get the info simply and correctly.

There's no secret formula, a .4 will be just fine. If not comfortable for the user, they can build higher next time.

Just for the fun of it, I would say
P=(I×I)×R so 60W=Isquare×0.2 so 60w/0.2= I square so I=17,3A
Since series the voltage doubles, you'll need 8,65A
Therefore 8.4V=8.65A × 0.97ohm.
Single 0.97 ohm coil

I'll bet that was one hell of a hit with a .2 single coil! Jesus!

First mod I owned was a MCM clone, way back in the day...I did the same thing immediately - I threw a "normal", .18 or so build rda on top, and coughed for a minute straight! Burnt juice, burnt cotton, burnt tongue! But, I learned....

Cherry Bomb!
