OMG, I think I'll go back to mechanicals.
I think I must be cracking up, and it is a figment of my imagination that my batteries last longer when I increase my coil resistance, but maintain the same wattage.
I'm losing the will to live.

All I wanted to know was how many wraps for a 1.5 or lower coil?

It depends.

I always use Steam Engine

[bobby00]

Me too but I just wanted 2nd opinion and all this happened lol

Mine eyes have glazed over and its like thhe curtains are drawn lights are on but there is nobody home?

Sorry that I have been called a trouble maker All I wanted to know was how many wraps for a 1.5 or lower coil?
I can just about wire a plug all thi tech talk has put me to zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

Ask a simple question

Is that a clockwise or anti-clock wise coil you intend to build?

If you have the coil master coiler, you have the option

Think of the converter as a gear box, it changes more than one parameter, rpm/torque or current/volts, ignoring losses they have to balance and have the same energy on both sides.  As rpm goes up, torque goes down, as current goes up voltage goes down and vice versa, while energy stays the same.

You have just not grasped that the current from the battery is normally different from the current at the coil with a regulated mod.  It has to be because the voltage is and otherwise energy would be being created or destroyed which defies the laws of nature.  You understand the coil side, but are stuck thinking that a circuit must always have the same current, which is only true for a single path or loop.

So it is my imagination that the battery lasts longer with a higher resistance coil at the same watts?

[jtc]

I would imagine it would last longer but it should be a constant power rather than dropping off like a mech 🤔

I totally agree with you!
I know from empirical tests that my batteries last longer.
Yes I was arguing from the o/p side of the magic box, but extended time between charges proves that less energy is being drawn from the battery with the higher resistance at the same wattage.

I've heard that a lot and there could be lots of reasons, like having your coil hotter will not give you more vapour over a certain point and higher res coils would tend to have less contact (bulk) and get a bit hotter than larger lower ohm coils.  Lower res coils, more bulky coils could be using a fair bit of the power to get to temperature.  Then there's air flow and wicking..... , so hard to qualify and pin down a single reasons, I certainly wouldn't like to pretend I knew.  A VW board could be a bit more efficient, but Evolv are one of the few who publish the figure and it just a flat percentage.

I would second that one - in my experiments with thicker gauge wire, I find it takes a while longer for the coil to heat up, then it tends to overshoot...

Surely higher resistance, with the same wattage will result in slower battery drain due to lesser amps? it's the amp pull that kills the battery isn't it?

If I have it right, according to VapingBad, No. The power watts used is the deciding factor, so a .1ohm at 50 watts drains as much battery power as a .5ohm at 50 watts

Now to get the same cloud age with a .1 you would need more watts and that would use more battery power.

Maybe it's different for regulated, due to the circuitry, but..

1 ohm at 50 watts pulls 7.07107 amps, whereas
0.3 ohm at 50 watts pulls 12.90994 amps?

Maybe i've just got it all completely ass backwards.

I suppose wattage is the "power" part of the calculation so it makes sense!

I thought amps had a factor though

[Bluefish]

I think it's just that with a lower ohm coil you need more power so drain the battery quicker, you just need batts that can handle however many amps the watts produce, anyhow when it's flat you need to recharge lol
