Premade coils wrong resistance

[Arvellon]

Hi,

I'm using the vandy vape pulse bf mod and I am looking for a good single coil build around .250 ohms. So I purchased a pack of Demon Killer Tsuka premade coils which claim to be .250 ohms on the package but when I test them, they are .460 ohms. This is not at all working for me because the pulse bf is single battery and it simply can't handle a resistance that high (almost no vapor).

So I was wondering, are the coils not actually .250 ohms or am I doing something wrong? Also if someone has an idea on how to get a resistance of .250, I'd apreciate it.

Thanks

This is the problem when you buy pre-made coils. You can't trust that they will be what they are advertised to be. I appreciate your concern about safety, which is a good thing.

If you use two identical 0.46 ohm coils (dual coil build), you should end up with a total resistance of 0.23 ohms. Will your battery handle a 0.23 ohm build? What battery are you using in your mech?

Maybe you should learn to make your own coils?

I'm using the samsung 25R battery (20amps max) and I did before make my own coils but I have crappy wire (23awg ss317L). But I'll try using two coils thanks!

I will give an update when I have tested it.

Isn't the Pulse RDA a single coil deck?

I'm using only the pulse mod, the RDA I'm using is the Vandy Vape Mesh RDA

The 22mm is. The bigger one isnt

Mesh is a whole different animal. Are you using mesh or regular coils?

If you're using a single battery mech with exotic high mass coils you will struggle at any resistance.

Looked it up and a "Tsuka" is essentially a triple 26g coil with an added passive heating stage. No way you're getting an acceptable vape on a single battery mech, the resistance is the least of your problems with that. The ramp time should be epic, no need to test dual "Tsuka" it'll only get worse.
A review in a German shop confirms your ~0.45Ω reading, they just seem to come that way. Maybe their stated Ohms is for dual coil? Pretty far off target otherwise.

What you need for your single battery mech is a low mass high surface build.
Got simple 28g wire? If so I'd try a parallel 28g coil, should work fine.

My single cell mechs are all built with either a 5 wrap 3mm ID Ni80 fuses Clapton 28x2/36... It's around 0.15Ω, or dual 22 AWG SS316L built to about the same resistance. I am using either Ampking/iJoy 5 leg 20700 or LG HB6 30A cells.

Your "crappy" 23AWG SS316L will make a dandy coil 3mm ID 8 wrap 0.3Ω

Big exotics will need a regulated device.

Also, I'm a bit confused, usually a higher resistance build will consume less power from your battery than a lower resistance than that. Have you tried ONE of your exotic coils in your mech and seen how it performs? It may or may not be a "satisfying" vape but the outcome may have more to do with the type of coils you are using, rather than the resistance itself as more wire is going to result in more surface area and flavor, possibly, but will consume more battery life to heat it up. I might be tempted to just try a single build and see how you like it.

I'd agree that with a mech more surface area but maybe not more MASS is going to give you a better outcome, battery wise. Although you can also try two of your coils if you wish, but I would be concerned about the amount of metal in the build. Yes, you want to stay within a safe resistance, but the battery will also strain to heat up that amount of metal, you may be better off with more simple builds, and maybe a thicker wire, but still a simple build and etc.

On a single 18650 with a 20A CDR, this is the way to go.

I would rather have parallel or twisted 28 than wire thicker than 26. Yes, you get lower resistance but thanks to the value of Pi, the coil surface area you give up ain't worth it.

Maybe some 26/36 Clapton wire.

am I doing something wrong?

Might like to read the wisdom of these posts,they say it all for me:

Resistance is futile. Ohms are not king. Wattage is. • r/electronic_cigarette

Salut à tous ! Il faut que je post messages si j'ai bien compris avant de pouvoir faire quoi que ce soir sur ce forum. Donc en voila un ! Bonne journée

It'd be too bad to see you blocked.
