And unsure on the resistance it's been awhile and I don't remember


That's not a 35 amp battery.
personally I wouldn't use it for vaping.

Resistance is crucial. That's really the most important thing here.

I must ask, why are you using a mechanical mod?
From your post to seems you either aren't aware of the risks you are taking or your are acting carelessly with your safety.

This is the recipe for getting hurt.

Mech mods are for advanced users only. Whoever gave/ sold you this setup needs a slap.

Good on you for asking though.

First thing to do is put the mech away. Get yourself a regulated mod and do some reserch. Watch some videos on building, ask lots of questions.

The fact that your friend is using twisted 22 gauge is a red flag. I would not trust this person with my safety.

I've been vaping for about 2 and a half years I was just wondering bc I've never seen it done before

I would ABSOLUTELY NOT mix those coils. In fact I would never put two coils in the same device if both coils were not very close to being the same resistance. Why you ask? Because the coil with the highest resistance is going to take most of the heat. With very slight differences the thermal variance will be minor, but big differences can cause one coil to get really hot and the other one not so much. In essence draining your battery faster and putting more of a load on it and getting very little benefit in return. Multi-coil setups should always use the same type wire, the same size/diameter, and the same number of wraps.

Also with mechs and sub-ohm setups you really shouldn't ever fire it if you don't know the resistance of the coil, how many amps that is going to draw and if your batter can handle that load or not. Unless of course you don't care if that battery explodes in your face.

Are you talking about having one coil being 22/28 and one 22/22 in the same RDA?

If so two things would happen. The resistance would drop like a rock and the coils would heat up with very diferent ramp up times.

Actually the coil with the higher resistance will produce very little heat in comparison to the lower resistance coil. Strangly in this bizzaro sinario the 22/22 coil would make most of the heat but take a long time to come up to temp because of the very high mass.

Thanks for answering my question
