Heyyoo!

I have a question regarding amps on my Alien mod. I´ve been vaping on a smok R80 with a baby beast for a long time and today i upgraded myself to a Alien 220w mod with a original TFV8 Cloud Beast. I came home and popped in some 18650´s and primed my coil and filled up the tank.

I read the screen after my first puff and it said i was pushing 25 amps? @90 watts. This doesnt seem right or is it Reading some other values im not getting here. Anyone that is up to par with how Everything works with the Alien that could clearify?

Best regards

Ignore those amps. They do not relate to draw from the battery at all. In fact, I don't see how they serve any purpose at all.

Okey. Well i´m pretty new to the technical part of vaping so i though i´d ask Before just ramping stuff up and burn my house down. :p Might sound silly to an experianced vaper but i like to keep my stuff on the safe side

Not silly at all!! The only thing silly is when people don't ask.

Not sure what you guys are talking about but, based on Ohm's law, 90watts @.15ohm is pulling 24.5amps from the battery.
Ohms law doesn't apply to the amp draw at the battery with regulated mods. Watts law does.

Watts / battery voltage = amps

Account for the chip efficiency and use the mod voltage cutoff. With parallel mods the amps are divided by the number of batteries, with series mods the battery voltage is multiplied by the number of batteries but the amps are not divided. The result is that the amp draw per battery is the same with parallel and series mods.

Per watts law. Thats 23 plus amps on 4.2volts about 12 on 8.4 and 7 if 3 batts in series.

SO YEAH THE AMPS DO MATTER IN A REGULATED MOD. You might not cook the batts....... mods circuits should save itself first.....

But yeah a regulated mod can draw less Amps from the batteries most of the time than the atty is drawing from the mod. It is also possible for the mod to draw more amps than a battery is rated for or in condition to handle.

Of course amps matter (I never said it didn't), but the draw isn't calculated by ohms law. And yes, it's fully possible to draw more than the cdr of the batteries, and with the ridiculously, dangerously overpowered mods today it's likely to happen a lot (200, 220, 250w in too battery mods... Unsafe).

In the above example, using Watts Law, you still end up with a 24.5amps draw on a single battery (90/3.67)

Fwiw...... that 24.5 amps at 90 watts is WHY we suggest married sets of batts in a regulated mod.... the mod will pull the majority of those amps from the weakest of the batteries first or more.

Path of least resistance kind of thing.

The alien should be able to handle the load... being a multi battery mod... but the reading is correct.

Actually, the Alien being a two battery mod with a cutoff at about 2.9v, the draw per battery is about 17 amps (assuming a 90% chip efficiency), no matter the resistance of the coil.

99 (90w + chip inefficiency) / 5.8 (two batteries in series) = 17 amps

On a single-battery mod, with a cutoff at the more common 3.2v, the amp draw would be about 31 amps, not 24 and change.

Obviously, I don't understand this very well!!!!! I have 7 dual-battery mods so I guess I need to do some reading.
You also need to learn difference between 2 batts in series vs parallel. Because your 2x mods could be eitherway. And in a few mods Both ways.

The amp draw per battery is identical in regulated mods though. In parallel mods the amps are divided between the batteries but in series mods the voltage is doubled.

In theory yes... in reality...Only if the batteries are also identicle. In everyway....... the weakest battery carries the majority of any load. It represents the weakest link in the chain.

Laws of science are the same for mods.
