Would this be safe?

[VAP3MICHIGAN]

Hey guys, Im not new to vaping but fairly new to sub-ohming and just wanted to confirm this wether this would be a safe build or not.
I have a new 18650 AW 2200mah in a Copper Penny mech mod, using a Dodge V2. Ive been playing with coil builds and have been sticking to the .3 ohm-.5ohm range. But my question is for my latest build, 22ga kanthal wrapped 4 times, coming in at a .18 ohm. Now personally i dont feel safe using that low of a build especially with a fully charged battery. But a so called "vape master" at my local vape shop assures me that this is safe, and that he vapes even lower ohms. I just dont trust that, i want to be as safe as possible when sub-ohming. So what do you guys think?

From my understanding, you should stick to 20% head room, so I don't think I would go lower than .25 or .3. You can go to steam-engine and check out the battery drain. You can pop in your battery and the ohms and see where it's at.

That's pulling 22 amps - I wouldn't do it without a battery I was positive was capable of 30

A genuine AW 18650 2200mAh has a MCCD of 20A. Without considering the pulse or momentary discharge/time values... you have a negative headroom of 3.3 amps, at 4.2V & 0.18Ω resistance.

Lets say for a moment that you have a conservative pulse discharge rate of 1.2 X 20A = 24 amps. Might be more, might be less, but... you still have less than 1 amp, or under 5% head room.

As the pulse-to-time amperage is an unknown... even though the "vape master" says it's OK, unless he's got factual data direct from Andrew Wong (AW) to support his recommendation... you're trusting your VMs guesstimation, rather than any actual hard data.
IMO - any supposed vape master that tells a customer it's OK to push beyond a batteries limits... is an irresponsible fool, and they take you for one as well.

If you've never used Steam Engine, it's the first hyperlink in my sigline. The second hyperlink is my advanced users guide for Steam Engine. Might want to take a look, VAP3.

Cheers

Bottom line , NO , you're exceeding the continuous discharge rating of 20 amps by more than 3 amps with a freshly charged battery at 4.2 volts . I agree with the others that stated your so called vape master is an irresponsible fool for telling you that it's safe . You need batteries with a 30 amp CDR to be safe with that build such as Sony vtc4's or vtc5's . Here's a link for a simple calculater to help you out . Ohm's Law Calculator

Thanks everyone for the clarification, i typically use steam-engine, which is why it made no sense to me why he would tell me that its okay to vape that low of ohm with that battery. Clearly he is no vape master, more of a master fool, lol

a so called "vape master" "I just dont trust that,"

Don't. If somebody introduced themselves to me as a "Vape Master" I would ask to see there Douche bag card and walk away. Just sayin'...
