First Mech Mod & RBA Build, will it be safe?

[rindey]

Hi ECF,
Hoping for some newbie love - I have a Nemesis Clone, Sony VTC5 Battery with a kayfun 3.1 clone sitting ontop (looks smick!)

I built a 0.9 Ohm coil from 28 AWG A1 Kanthal last night (measured the Ohms on a VAMO V5 as i don't have a Ohm Meter) and using the vapers toolbox app on my phone it says i'm pulling only 2-3 Amps from the battery. I have no idea how to confirm this, all i know is that the VTC5 is 30A Continuous and 60A Pulse.

Can anyone point me in the right direction or help? I don't want to blow myself up here
I won't lie, i have been using the mod so far - the tubing hasn't gotten even remotely warm

As long as the vamo can measure the resistance, you shouldn't have a short. Just make sure your coil isn't touching the base of the build deck, or the mod will short. I know the feeling, the first one is always scary. And the VTC5 can go down below .2 ohms, you shouldnt have anything to worry about as long as you don't have a short.

Welcome to ECF rindey... good to see you using Ohm's Law.

Actually, I think you may have entered 2.7v instead of 3.7v nominal into your phone app. At 4.2v it's more like 4.7 amps... but with the VTC5s 60a pulse, you have a huge margin of safety. As stated... short of a dead short, you have nothing to worry about.

If you want a bit more information, click on my second sig line hyperlink... and have fun. ;-)

Agree there is a little bit of info you need to know just incase you overlooked it. Pay close attention to your battery drain one of the main issues with a Mech mod is there is noting to prevent you from over discharging your battery so test your battery often. Try maybe testing every couple hours till you get to know your battery per your vaping style. Other then that you can test your atty on your vamo to make sure it remains un shorted. I usually test mine with a meter every day before I start vaping it if I'm running it on a mech mod.

If the vamo reads it its safe to vape

Wow! You guys are awesome, didn't expect so many replies so quickly! ECF is the place to be! Thanks everyone, I definitely appreciate your feedback.

I want to get lower Ohms in the future but even 0.9Ohms with 18mg Nic Juice is a bit strong for my preference. Lucky I've got some Five Pawns 12mg sample packs sitting just waiting to be vaped as soon as i'm confident with safety and the build quality of my coils.

I've been lurking on ECF for quite some time, decided to go with the 'choc-biscuits' of rebuildable supplies thanks to ECF's reccomendations - 100% organic cotton and a1 kanthal direct from Temco (loving it!)

State O' Flux I'll be keeping a close eye on the deck making sure things are hunky-dorey. I'll definitely follow your hyperlink and read up - thanks
epicdoom I'll be buyng myself a Ohm Meter & a 510 Volt Meter to keep an eye on things Thanks!

Yep, look good to Vape, everything looks 5 x 5. I would drop down to 0.7 or so and give that a ride.

You might want to pick up a atomizer ohm meter, more accurate and can track ohm drift in the build easier.

You ain't going to blow your self up, and it's not the warming of the tube that needs concern with, when an atomizer gets hot, it will pass the heat onto the tube, it's the battery one needs to keep an eye on. You could cause the bat to vent, but you'll need to work hard at that to make it happen. Could happen, but you are looking good to vape to me.

You are demanding more like 4.6 amps with that build, but still, with the VTC5, no prob there. Here's the Ohms Law Calculator that I like to use.

Sounds like your good to go. However, as others have said, I too recommend that you pick up an ohm meter. I'm not saying that the vamo won't give good readings, It's just that I have a lot more confidence in having the meter. Being a little OCD, I sometimes test on multiple devices (vamo, MVP, etc), but that's just me. Besides, I just enjoy screwing around with this stuff.

vapecalc.com says

a full battery = 4.2v

a coil of .9 ohms

would be outputting:

19.6 watts

and 4.67 amps

i allways check with vapecalc before applying power to a coil i make just to stay on the safe side hope this helps

I wouldn't just say safe, i'd say super safe. As long as the nautilus can keep up with wicking it, you're fine. My builds are usually around 50-60 watts / 6-7 amps with no problems. That's with vtc4's, vtc5's, and efest high-drain 2500's. But I only use drippers any more so I wouldn't suggest going that hot of a coil in a nautilus, lol.

 

[dice57]

lol dns, yeah a Naut chokes at about 11 watts. chuckle, chuckle. snort. lol. But a Kayfun style rba can easily handle 30 watts if built and wicked properly.

 

[Jaepoori]

your battery is capable of handing down to .3 at least. You should be good.

 

[KitchenSoap]

I'm running .15 ohm on a trident with a Sony 30 Amp battery. You should be fine.

Cheers All!

Been vaping on the Nemy with Kayfun all day now! Can't get enough flavour! It's awesome

Next build will be on The Kraken, however I got too excited when it arrived and chucked juice in it and PWHOA machine oil taste is foul! Gotta clean it out and start again. Got some SS Mesh with it too, first time working with the stuff.. Could be interesting ;D

 

[Christian Aaron Ellis]

My first build was on a Kayfun. You shouldn't have to much of an issue. I am running at .9 ohms myself and the vape is pretty warm with the stock drip tip.

As a theoretical question, what would happen if the voltage drops below 3.7 volts on the VTC5 and you keep vaping?
I've been monitoring my usage and I've been charging them back up once they hit 3.8v to be safe

3.7 is the nominal voltage and will not cause any problems. It's when you go below 3v that you might damage the battery. Most regulated mods will turn of when the battery is down to about 3.2v, to leave a safety margin.
