I'm new to mech mods, i wonder is this safe ?

[thesafevaper]

Hi guys, i have been vaping for 3 months now. I started with an ego Twists and then i upgraded my vaping gear to a Kanger subtank mini on top of an Eleaf 30w, its work just fine,I'm quite happy with the flavor however the vapor production is limited..

So i did quite a lot of research about RDAs in order to create bigger clouds. I tried to learn all stuff about wicking,coil buildings, ohm's law,... And i bought a Mr.Owl RDAs to try it my self, i built a 1ohm single coil with 26g kanthal a1 wire, and i used it on my eleaf 30w at full power, it vapes just great, and the vapor production is much more satisfying.

But then i found out that a 30W VW mod can not push an RDAs to it full potential, so now I'm getting my first mech mod (Torchlight mod by Ephro) it's on delivery right now and i will get it in a few days. I did some more research about mech mod And battery safety but some is too confusing for me..

So now i intend to build a 0.5 ohm dual coils, and use it with a Samsung 25R/20A 18650 2500mah battery. I know that my battery when fully charged it will draw 4.2V, so 4.2/0.5 =8.4 amp min , my battery can pump around 20amp so i will be perfectly safe ? How long does it usually take for a 18650 battery with 2500mah to drop to 3.7V so i can stop and recharge it ?

That's all what I'm considering right now, i just want to make sure that i have enough knowledge to vape safety with a mech mod. Thank guys.

Totally depends on how long and how often you hit it. But you will feel the hits getting weaker as the voltage go down. I have 3 mechs and 5 RDAs, honestly the mods we have now can do huge clouds.

thanks for the advice, do you think that my battery choosing will fit with my build ? The numbers i worked out shows that it will be fine but i just wanna make sure

That's ~30W or so on the stainless steel Torch Light assuming a generous drop to 4V (more like 3.8V or lower on fresh cells). Unless you prefer cool vapes or building with 28g or 30g wire, consider building slightly lower so long as your 25R is relatively new with minimal use time.

More power doesn't equal more performance or more vapor.

Theres a lot more to it than just slamming 100 watts through an RDA.
How you build your RDA, coil placement, airflow will determine your cloud size, not the battery.

Absolutely not. A good build, proper placement of the coil the VG/PG ratio and many more factors.

It isn't all about watts.

I vape at 12.5 watts or lower and often chuck larger cloyds than someone using .5 ohm coil and rocking at 40 watts. And here I am with a .8 ohm coil and vaping at 10-12.5 watts.

I don't know the Torchlight, but it has a 510 pin so it's not an immediate danger. I will further say-- I'm a mekkie from way back-- I wouldn't put any battery in a mech but a Sony VTC4; I like the thicker safety margin and I'm willing to give up 400 mAh to have it. That said, the 25R is a good battery and should perform well under the conditions you describe. Building a 1 ohm coil in 26ga must have been fun; on a 2mm mandrel that's a 10 wrap. You know, right, that to make a .5 dual system you need 2 x 1 ohm coils, not 2 x .25's, right? I would recommend you try 28ga, or twisted 30 or 32 ga in that resistance range. Using that 25R, I really would suggest you stay at .4 ohms or above in order to avoid overloading the battery in case of a stuck button or something. I might also mention at .5 ohms you will only be putting 35 watts on the coils, so I am not sure you're going to notice a huge difference over the 30 watt machine you're now using. However, as has been said, it isn't about watts or ohms, it's about knowing how and surface area. (Surface area is why I suggest smaller wire or, better still, twists or even Claptons.) For pushing an RDA to its full potential, I do not suggest a mech mod. You can get a lot more power from a regulated even with a single battery; and on a mech the only way to change your wattage is to recoil. I don't have an Owl, but just looking at the photo, I suspect it will be air limited long before you get it into super low builds and high watts. Using identical builds, I think you would get more cloud from a Mutation V4 or a Velocity; the first of which can be had authentic under 35 bucks and the latter as a clone for 15. You will know when the battery wants changing; the vape gets weak. Still, this will be a good learning experience for you. Coil placement and air vs power are key to good RDA performance and I don't know any way to teach this other than by experience. So have fun, and shoot us some questions when you have some. And welcome to the wonderful world of mech mods, by the way.

This just made my day, thanks for your help.

I love 27g for dual coil mech builds. It just works for me. I do about 8 wraps each at 2.5mm for about 0.55 ohms. And get a satisfying vape down to 3.5-3.6v on the battery. That's my formula, but of course YMMV.

 

[sonicbomb]

If "is this safe?" is the question, the invariably the answer is no.

 

[blubeard]

Try a 28g, kanthal triple twisted contact coil on a 2.5 or 3mm screwdriver on that subtank rba deck.
I run these on mine and get awesome flavor and clouds at 25 to 35 watts.
