Resistance ???

[angie124]

I have a pico battery which I'm using with a cleito with a 0.4 coil. Don't really understand what the display is telling me

I'm running it at 45 watts. The display is saying 4.14v and the other figure I guess the resistance 0.38. Should I be running the resistance at a different figure ? Sorry if a stupid question don't really understand
Any advice appreciated.

The mod reads the resistance of the coil & determines the voltage required to provide the wattage you set. You will notice the voltage changes automatically as/if you change the wattage. Hope this helps...

Hi Angie! With variable Watt devices, you basically plug in two "knowns" and the third will "calculate"

In your case, your coil is a 0.4Ω coil, but that's never "perfect" it will likely "wiggle" plus or minus a bit. SOOOOOO, "knowing" your resistance (in this case the Pico reading 0.38) and the Watts (in this case 45) the "math" behind this is that Watts = Voltage^2/Resistance. Voltage^2 = Watts * Resistance, so Voltage^2 = 45 * 0.38. This is about 17.1. If you take the square root of 17.1, you get about 4.138 (rounds to 4.14)

The only way to "run the resistance at a different figure" is to change the coil. Set it to how you like it, and you're o.k.

Oh I see. Ty.

No Such thing as a stupid Question if you don't understand something. The Only thing that would be Stupid is if you Didn't Ask when you want to know something.

Ask All the Questions that you might have. It's a Big Part of what the ECF is for.

Resistance is a measurement in ohm units. Resistance gives you an idea of how easy electricity will conduct power through the heating coil. Low resistance coils allow electricity to flow more easily and makes a warmer vape, but that means they also draw more energy from the battery. High resistance coils restrict the flow of electricity; this draws less energy from the battery but produces a cooler vape.

The regulator chip takes care of the calculations on the atomizer side, you don't need to worry about it. The regulator sends the wattage you set to the atomizer by multiplying amps by volts. A higher resistance coil will usually need more volts, a lower resistance coil will require more amps. Though as I said this academic, the regulator takes care of business for you.

1.2 ohms at 100 watts - 11 volts and 9 amps.
0.6 ohms at 100 watts - 8 volts and 13 amps

How much amperage is drawn from the battery side of the equation is your responsibility. The more wattage the higher the amp draw, and this will increase as the battery voltage falls. Plug the numbers into steam-engine and use an appropriate battery.
