Unregulated Box Mod

[rangerrobin]

Hello and pardon me, I couldn't find a subforum for this.

Today, I received a tuglyfe mod. My 1st ever unregulated mod. I've tried several of my toppers on it, but haven't had a decent vape yet.

I installed a brand new, married, set of fully charged Efest IMR 18650 3.7 2100mAh 38A positive ends up and at .5 ohms it feels weak.

I'm comfortable with building and my regulated set ups rock. I don't have a meter. The 3.7 is what's printed on the outside of each battery. Did I get the wrong batteries or what?

Thanks in advance for any info/direction you can provide.

You need to get a resistance meter.
The reason that your vape is not good is because .5 ohm is too high of a resistance.

Okay, does that leave me a range of .1 - .4 builds? After work, I'll build a lower ohm coil.
Thanks for your input.

It really depends on the gauge of wire you are using. If I was building it with 24g, I would be doing a .2 build. With 22g, .15. If you are using higher gauges like 26 or 28, it will be closer to .3

This would be for dual coil builds.

 

[rangerrobin]

Okay, so it sounds like I need to build under .4 to use this mod. Correct?

Yes definitely. I would build it under .3.

10-4. Thanks again for your input.

FYI those cells have a 20amp CDR, not 35amp as the labeling states. You are better off with Samsung 25R or better still a pair of Sony VTC4.

Where can I buy authentic Sony VTC4s?

I get a very satisfying vape at .5 on my parallel box mods. It definitely isn't too high of a resistance.

What is your regulated setup?
What voltage do you vape at on your regulated setup?

With unregulated, you are limited to 3.7 volts, so you have to make a coil to suit 3.7 volts.

a 24 gauge kanthal, dual coil, 0.5 ohm, will be weak at 3.7 volts.
a 26 gauge should be ok.
a 28 gauge might be a bit hot, but workable.

No, you can likely build at any OHM you chose, within SANITY levels. Safety says to stay above .2 ohms, many don't.. Unless you have a meter that really read that low, MOST don't. But you could also build and run for weeks on a charge at 3ohms.

So far, I've gotten a decent vape off a .4 coil. I will try a .3. If I understand correctly my only coil options, with this device and these batteries, are .3 and .4?

Thank you for the info!

I've been using IPV2s, and IPV Mini II, and an IPV4S. My coil builds vary, as do my watts and voltage per build, device, juice, etc. I tend to like .5 -.8 anywhere from 30 watts to 45 watts. Voltage varies with the wattage.

I said 3 OHM as in THREE.ZERO and even higher.

What wire do you use? Without that, ohms and watts just tells me about how fast your battery drains. The wire determines the HEAT.

Maybe we can help come up with an equivelent build for a mech.

Wrong. You have two VTC4 cells in parallel. You could technically draw 60 amps and still be within the CDR, if you want to stay below CDR. You can see this for yourself using ohms law. You have many options. If using 24g, I would start with a .2 ohm build, which will be at half the CDR for your batteries. Measure your resistances. Make sure there are no build errors. Do it right and you won't have any issue.

28g Kanthal. I don't know the mm of the little blue screw driver, but will find out and try the calculator. Thanks for your assistance!

Oh, I would think that 28g should be fine at .4 ohm. Maybe your build isn't good. Can you post a picture? Are you using an RDA?
