What's the best Ohms for a new mech user.

[AlanV]

0.15 - 0.22, although I find the 0.22 a tad weak, for flavour and the 0.15 a bit too warm, so somewhere in between, which is not always an easy target to hit.

Yeh, that can be hard to achieve on a single coil setup. Worth a try anyway.

Would this be a good setup for my first build on the mech.
It's 510 pin is protruding and it's solid.
The Vape in bypass is almost perfect.
Sorry for all the questions but I just want to get it right.

Mechs can be a bit of a dark art when calculating the wattage that gets to the coils.

One thing I totally agree with is you MUST stay within the amp limit of the batteries - with the 30 Amp Molicel P42a that limit is 0.14 ohms. Don't go below 0.14 ohms for any reason.

When working out the wattage of the vape take account of voltage drop and battery sag as 4.2 volts will not actually make it to the coils even with a full battery - I recommend you start with 3.7 volts as this is a more realistic figure.

Using 3.7 as a guide you will get approximately-

DUAL COIL

0.14 Ohms - 97 Watts
0.15 Ohms - 91 Watts
0.16 Ohms - 85 Watts
0.17 Ohms - 80 Watts
0.18 Ohms - 76 Watts
0.19 Ohms - 72 Watts
0.20 Ohms - 68 Watts

SINGLE COIL

0.20 Ohms - 68 Watts
0.21 Ohms - 65 Watts
0.22 Ohms - 62 Watts
0.23 Ohms - 59 Watts
0.24 Ohms - 57 Watts
0.25 Ohms - 54 Watts

The above is a very rough guide of the actual power vape you are likely to get at the 510 with each build assuming the voltage drop/battery sag is around 0.50 Volts when the battery is fully charged - the power will gradually reduce as the battery discharges.

Personally I find 0.14 Ohm builds too hot and generally stay in the 0.16 to 0.17 range for dual coil builds. With singles I tend to stick closer to the 0.25 end than 0.20 as that also gets too hot for me. (This is with atties with the option of plenty of airflow)

I would advise you factor in voltage drop/battery sag to assess the actual wattage you get at the coils BUT DO NOT INCLUDE IT when you are working out the Amps you are pulling from the batteries - that is an express route to pushing your luck.

If you find 0.14 Ohm builds too tame (you're a nutcase) you can go as low as 0.12 if you use 35 Amp Samsung 30Ts, if 0.12 Ohms isn't enough (you should be sectioned) then consider a mech with more batteries.

Hope this helps

Looks safe. I use dual coils and build to .19 - .2 for fruits/drinks and .17 - .18 for custards. Its a confidence thing so get to the back door and try it, soon you will be drooling over the stacked mods which is more research for safety.

Thanks so much for that.
I'll copy this to my note app so its always to hand.
