Mechanical mod help

Ok I know all about ohms law and everything. I just want someone to double check my math for me. I have two 3.7 volt 2500mah bateries in a series on a custom made mode with a rafale x rda. The batteries are rated for 20 amp draw. If I have my dual coils set to .6 ohm then I'm ok right?

If your rda on a ohm meter is reading 0.6Ω you should be fine, even with a full 8.4v blast and dropping resistance by 0.1Ω for leeway, you are still only pulling 16.8 amps. The only issue that would come up is if the coils are labeled as .6Ω each, then you will be hitting over your amp limit. I hope this answer helps.

The absolute best answer I can give you here, is that you should already know the answer or shouldn't be using that mod. I don't want to be the one to say "Sure.. go ahead" and it blows up in your face. Mechanicals are not toys, nor a novice item. They are for advanced to experts only. You need to be able to stand up, look yourself in the eye in a mirror and firmly state "that was MY (your own) fault" if anything happens. Either you have the confidence in your level of experience or you don't. If you don't, stay clear of mechs and multicell mechs until you can firmly state that you do.

Now i am not putting you down in any way, nor am I just being a jerk. But it is your face you are betting on, so it is better to know for sure before asking a stranger if your build is ok.

Thanks for the help. my coils are .6 ohms total.

Each coil is a .3 ohm coil, the rafale doubles the resistance of your coil with its dead center post. It's basically connecting both coils making it a larger single coil, which is a pretty sweet rda to use on series mechs.

I'll bet that I have way more experience than you with mechanical mods haha. Every time I build a new mod I do the math over and over myself until I know it is right. As you said this thing up in face, so i believe it can't hurt to get multiple people to check my math for me because we are all human and makes mistakes therefore we have to have other people check up on us and the things we do so if we are wrong they can help and maybe save someones life.

Ah right on, well thankfully he had the Ω reader so covers my butt a bit. Didn't know that about the rafale, crazy $Ħ*† they are coming out with. Can never keep up with everything dropping all the time.

To original poster, sorry for my blunder, thankfully the community jumps in when others make mistakes and I am happy they do. At least in this sense discussion is brought up if conflicting answers start to fly.

The batteries are rated at 20 amps or they are tested to be 20 amps?

I love it. It allows me to do some crazy builds I couldn't do before.

I love series decks, wish they had more. My favorite series RDA is the Modfather RDA, 30mm series deck!

I did not say experience, I said advanced to expert. You could have 10 years experience but that does not mean you have expertise. It just means you have been doing the same thing for 10 years. AND I will bet that I have way more expertise with mechs than you do. Since I KNOW my builds are good and don't have to ask. Point is, you are uncertain, so you need to increase your expertise until you are certain and depend on nobody but yourself for your mod and coil builds. Now take the advice or don't, just remember who owns the face you are putting your mod up to and who is pressing the fire button, and where the responsibility lies at the end of the day.

Like using this site. It along with some comprehension of Ohm's Law, an Ohm/Volt meter for testing builds on are all helpful. Gradually learning, consider myself intermediate to advanced. Don't ask if builds I do are alright too much now.

Last week I had a deep seated urge to use a dual Clapton set up. Knew that it was a little risky doing so on a single 18650 battery. Did it anyway because I also knew who was using the mod, me, myself, and I. The very moment I experienced battery drop off, pulled a slightly warm battery out of the mod and began building a single coil only.

Fortunately, nothing terrible happened. It could have and been quite terrible. Was I being stupid or ignorant, arrogant? No. I did it knowing the risk/s involved as well as knowing of having awareness of battery drop off. It was something I felt a need to do. "What's the limit?" I found my limit and probably will not push it any more so.

The application, or choosing to not apply knowledge is wisdom. Sometimes one gets wisdom from Cracker Jack boxes or books and sometimes from the doing themselves. Can I say either is the better way to go? Nope. Both have their advantages and disadvantages. A person needs to balance their own path/s for themselves. Only my two pennies, all the standard disclaimers, warranties apply.

LOL you could be sucking on cartos these past 10 years with never even attempting to rebuild anything. Just makes you a user.

Dual claptons could be done, but you would have to build specifically for your target resistance and plan ahead for heat flux. Im thinking, 28ga NiChr or kanthal, parallel core with 32ga/34ga SS wrap would be within limits. You have to do your own math of course. Basically, you want very light weight claptons, to trap juice for flavor, but not stress your cell.

What I've on hand is 26 awg inner core wrapped with 32 awg. Possibly
could create 28 awg inner core with 30 awg Kanthal, lacking ambition
to do so though. Not denying it can be done. For my own pleasure, fine
sticking to using a single Clapton on a single cell. Tried my limit and
got wearied enough to suit myself. *chuckles*

Reminds me, need to do some dry burn & tuning tomorrow / later on today.
Been sucking vapor off a coil for about two weeks now, and the juice
is probably around 20/80 (PG/VG). The higher vegetable glycerin helps
lifting out the fruit elements to this particular juice blend, at least
for myself.

Of course, one pays for extra vegetable glycerin with a little more
residue hanging on the coil. Oh well, like I'll complain when the coil/s
run me a cost of pennies per unit, in comparison to Pro tank coils
which used to run around a buck a pop for me.

At worse case, I'll build and install another coil/s setup on the Goon
deck.

too much wire mass for a single 18650, what I run on my 18680 tube's is SS 28g-32g core and 36g - 40g for Wrapper

Alright. :) ty. This morning instead of dry firing a single Clapton that seen two weeks of hard use with a high vg juice, I opted to wuss out and plop on a dual coil 28g. It's hitting around 0.70 (R) oHm net +/- 0.02. Keep working to dodge out that 0.02 miss of my target, as in I want to hit 0.70 solid all the time and not be +/- anything at all. Seem kind of stuck though in hitting that tolerance range. Could be better or worse I guess.
