Batteries and Temperature Control

[Boden]

I guess in my mind I always thought that a regulated mod used its buck boost or whatever it's called to increase the voltage, and not the amperage. That was my mistake. I always thought that if I set the provari at 5v it would increase somehow the voltage given by the battery, never ocurred to me it was the amperage. I was just happy it gave me that voltage until the battery died. Now I understand it better hehe

You are about to understand a bit more than most.

One factor that I generally leave out to keep it simple. Regulator efficiency.

Using: So, let's say his battery is near dead and is at 3.2v.

80/3.2 = 25 amps

Now lets assume the regulator is running at 90% efficiency and is actually pushing enough energy to make 80W of heat.

At 90% efficiency the converter is loosing 8W so it is really drawing 88/3.2 = 27.5A

But...in that case wouldn't it be giving 72w of power while set at 80w instead of pulling 88w due to the loss in efficiency?

Nope.. well if it was a really badly designed mod maybe.

Most mods when set for 80W make 80W of heat at the coil, that means the converter is drawing the power it needs to make 80W plus the losses.

It makes sense if we talk about battery sag under load, and the pv upped the amps to compensate during firing...but with the efficiency I don't get it, or does the regulator "know" it has that efficiency of 90% (for example) and pulls more to compensate from the start? Ah that must be what you're saying

(I was posting this before your reply but ecf went offline here...something with google chrome, had to restart it hehe).

Anyway I have officially been schooled here today hehe thanks Boden. Learned more today about safety and how amps work than in many years vaping kudos
