question about mods/rda

[charlieboy]

Hi im kind of new to mods ive been having my friend build coils for me and i want to try it my self.
I have a chi-you and omega rda clones and wondering what is the best wire to use for good vapor
and flavor also is ohm meter necessary? I have an efest 18650 battery.

thanks in advance

Ok the thing to consider is what wattage you want. 18650's are 4.2 volts or there abouts when fully charged. They should not be used below 3.4 volts. So assuming you want 8 watts you would want about 2.1 ohms so you will have close to 8 watts when the battery drains. The starting wattage will be about 10watts. 2.1 ohms would be about 1 3/4 " long piece of wire assuming about a 3mm diameter coil and 1/4 in leads on the coil. There are some cool apps to help with this. I use an android app Called Vaper's Toolbox and Eliquid Recipe pro which has a wattage, voltage, amps calculator. The wire used by the way would be 32 gauge. Almost forgot that. LOL

Vaper's tool box does the wire calculations.

You're going to want to have a Multimeter around. They're handy, and you can use them to confirm that the circuit is working. You can also use it to determine if the resistance of your coil is correct. I picked one up from the local hardware-type store for like 12-15 dollars. It's a cheap one, so I'm not expecting it to do any fancy tricks, but it does what I need it to do.

I use NiChrome wire for my builds... I've read that a lot of people get a metallic taste from it, I've never had that problem, myself. Maybe the metallic taste doesn't bother me. I've also found that it's a bit softer and easier to work with than Kanthal.

Also, if you're planning on building anything <1ohm, you really need to have an IMR battery, and I'd point you toward the AW brand. They're known for good batteries. They cost a bit more, but you get what you pay for.
