Voltage question

[R2sojr]

Now I'm really confused..lol Should I just buy a 30amp battery then?

lets make it simple.... the mod is a solid state transformer ( variac)

wouldnt hurt to have one

Working out amps with a regulated mod like you have is not totally straightforward.

Say you have 35W at 4.7V, Watts=Volts x Amps, so Amps = Watts / Volts. You are drawing 35/4.7 = 7.4 amps from the mod.

However the mod is drawing more than that from the battery. If the battery is fully discharged, it might be supplying only 3.2V, but still 35W. So the amp draw from the battery is 35/3.2 = 11 amps. It will be a little more than that, since the voltage conversion is not 100% efficient, but you don't want to get too close to the rated current anyway.

The thing to remember is that power is conserved. No matter what happens to volts or amps, the power taken from the battery is the same as the power delivered to the coil.

well most of it is... there are some losses in the circuit... capacitive, inductive, resistive losses occur...

How do I lower my volts?I find the flavor is better at 3.5v

3.5v / .6Ω = 20.4w
If you want to vape at 3.5v turn the power down to 20ish watts, take a few vapes then increase or decrease from there.

Holy smokes, I definitely gave you the wrong info. @Boden is correct, boost is what I was referring to. The voltage in my head is 7.4 after trying for so long to make a decent series unregulated box mod. Sorry for the confusion.

 

[R2sojr]

Can I build lower to achieve lower voltage. I have a .30 build that was around 3.5 at 40-50 watts and was perfect.

I forgot to add that I'm dripping

Use this to help guide you, lets you play with numbers before building.

you have a sig 75? whats your intent on getting the volts that low? I could understand the lower ohms if you were running a mech...

Use the down button

as baditude said everyone is different and uses different watts/volts and different resistances will require different voltages to satisfy that person experimentation is definitely your friend.

Built another set of coils and down to .28 at 3.3v. Ahhh my sweet spot.
