Is a gift that could become dangerous in a split second really a gift?

Folks new to mechanicals shouldn't jump right into extreme subΩ if safety is of any concern, you need to learn to walk before you run.
Again, for someone new to mechanicals .5Ω would be a decent starting point until you gain the knowledge, experience & necessary equipment to use a mechanical safely.

.16Ω - .18Ω is too low for a single 20a - 25a CDR cell and leave headroom under the CDR as a safety margin. Especially for someone new to mechanicals.

The LGHB series cells would support those resistances, 30a CDR 1500mah, battery life will be fairly short.

Be easier to learn to build your own coils in a safe resistance range for the batteries you have or intend to use.

You'll need,
A firm understanding of ohms law and battery safety & selection.
Know how to rapidly identify something is going wrong and what to do if/when something goes wrong.

Authentic name brand cells from a reputable vendor that have a sufficient CDR to support the resistance ranges you intend to vape.
Calculate amp demand using full charged 4.2v as a slight safety net.

An accurate way to measure resistance & check for shorts and a safe way to test fire / pulse the coils to adjust & fiddle with them to ensure they're heating from inside out.

Various gauge kanthal or ss wire & a mandrel/something of a known diameter of various sizes to wrap coils with, 2mm, 2.5mm - 3mm should do to start.
Start off slowly around .5Ω (or above) practicing coil building & wicking until you get good at it with simple single coil, then dual coil (halves resistance), then twisted wire coils & so on.

Learn how to disassemble clean & reassemble / maintain the switch/fire button & threading.

Learn the differences in top cap design, 510, direct to battery, hybrid & which delivery devices will work safely on which type of connection.

If what you're asking is how to vape .16Ω - .18Ω on a single cell mech using a 23a CDR cell safely,,, you don't.

If you've built coils before on a regulated mod, it doesn't really matter what size coils are "arriving with" the gift, does it? Just build some higher resistance coils that will be safe with the battery you have. Flat out, vaping that low ohms with that battery is dangerous. I'm glad you asked the question, but you really must take the answers seriously. If you want to use the "gift" coils, use them in a regulated mod.

Didn't really think about that honestly thanks for the idea Im going to make so coils for the mech soon to be safer

... I'm still new to mechs and I wanna do more research and learn before I use it
Smart idea. :thumb:

Learn how to use Ohm's law to calculate the lowest resistance (ohm) coil you can use with the particular battery that you will be using. You'll meet a lot of vapers who will vape with coils that are too low with certain batteries and proudly say "nothing bad has happened to me" .... YET!! It is far better to build at coil resistances that provide a safe margin of safety, especially with mechanical mods which have no built-in safe circuitry.

:rules:
The two most important things to know when rebuilding coils is to know the amp limit (continuous discharge rate) of the batteries that you will be using and the measured resistance of your coil.

I'm not going to use it at all until I know forsure what I'm doing that's why I'm trying to learn as much as I can

When using a Mech Mod, EVERYTHING you do is based around How Many Amps you are going to ask the Battery(s) to provide.

Ohms Laws say that Amps = Voltage / Resistance

So if I place a Freshly Charged 18650 Battery in a Mech Mod and then place a 0.16 Ohm build on it, when I push the Fire Button, the Battery will have to provide, roughly, 26.25 Amps (4.2v/0.16 Ohms) for as long as I hold down the Fire Button.

The Mech Doesn't Know or Doesn't Care what type of Battery you are using. It just holds a Battery/Atomizer that now has a Completed DC Circuit.

So it is Up to the User to ask... Can My Battery Safely Handle 26.25 of Continuous Amps?

Because if it Can't, the Battery could Vent. And if it Vents in a Mech, you could be Holding a Pipe Bomb with part of the Pipe Bomb in your Mouth.

So the 1st Question a Mech User should be Asking is what is the Maximum Continuous Amps I can ask a Authentic Battery to provide given it's current Age/Condition?
