What kanthal wire to use for 18350 battery?

[ZacUnknown69]

I'm new to building, so new my stuff hasn't even shipped yet. Since I'm clueless, I need to know what a safe wire gauge for 18350 batteries are. I know I can't do extreme sub-ohming, nor do I care to. So what gauge wire would be safe to use on an 18350 battery? Thanks.

Your desired resistance will dictate your wire, to be honest. 30 gauge is less wraps to get something 1ohm or higher, than 26 or 24 gauge would be. Wire isn't safe or unsafe, the coil build and battery quality are what primarily (not only) determine the safety. Here's a good calculator you can run a few checks to see how many wraps various gauges would require, for your desired resistance load.

Also, if you're clueless, spend quite a bit of time reading up on battery safety and everything else, so you are 100% informed on what you're getting into

With an 18350 battery just follow a few guidelines for best results. Use the above linked calculator to design your coil.

Don't go below 1.0 ohm. A standard 18350 AW delivers only 6 amp continuous. Running a battery at maximum will result in more voltage sag under load, and will cut your battery life in half. That small battery can be discharged very rapidly; lots of spares needed.

Depending on your vape needs. much over 2 ohms will begin to result in a weak, cool vape. That's the beauty of a regulated device.

Start by designing around 1.2 to 1.4 ohms. Use 28 or 30 gauge. 28 for a larger diameter coil, 30 gauge for a smaller microcoil.

The biggest difference you will notice in wire gauges is how fast the coil will heat up. Smaller is faster. Larger gauges may require a little preheat before drawing air over the coil, letting it heat up a little bit first.

As has already been said, wire gauge needs to be appropriate for coil resistance in a mechanical mod, which is what I think you'll be using.

Your battery will have a safe maximum continuous amp output (draw) rating that you don't want to exceed. Also, 18350's don't have much mAh (milliamp hours) so will empty quickly anyway. The more amps you draw from the battery, the faster the battery will empty. Typically 18350's have around 700 mAh while 18650 are around 2500, so about 3 1/2 times the run time at the same amp draw. Good 18650's are typically rated for around 6A max while good 18650's typically go up to 20A and sometimes 30A.

The amp draw will depend on the resistance of your atty and can be calculated using Ohm's law. Here's an online calculator for that. Plug in 4.2V and the resistance of your build and it will output the watts and the amps.

There is a great post witha lot of links to information that you will find helpful here; One Stop Reference Shop For New and Experienced Vapers. It ius indexed so you can read up on topics you chose. Baditude's battery blogs are very good. You need to be using high drain IMR or hybrid batts that are typically unprotected, never use ICR li-ion. There is a list of common high drain batts in there with max amp drain numbers. You need a way to check atty resistance and battery voltage. I suggest you start with a inexpensive DMM.

Take your time getting into this and ask away when you have questions
