Lets pretend I know nothing about ohms, amps, voltage (Battery question)

[Dougiestyle]

Ohms are resistance. The higher the number means less resistance. Edit: This is backward. Higher number = MORE resistance. Doh!

Resistance to voltage causes amps. Amps are regulated by most circuitry. If you exceed the amp limits, you can fry a circuit.

Mah is battery capacity. Capacity stays the same on a battery. The completed circuit drains the battery's capacity.

Generally you get ~1hr/100mAh. This is variable by resistance and vaping style (i:e. How long/much you have the button pressed)

Alot of people don't know much about circuitry and currents and the like. I didn't either. I payed attention and asked questions like alot of others and was educated about e-cigs and how they work. I hope this enlightens you some.

You have that backwards..the lower the number the less resistance to voltage. I learned that as a child when dealing with stereo speakers..lower ohm speakers will blow out easier and put out more sound for less power..they also will have less "noise"...

^This is correct.

Try to use this analogy if it helps.

With voltage, think of the current as a garden hose.

When you're talking about ohms, you're talking resistance, think of resistance as a kink in the garden hose. The bigger the kink (high resistance) the less current can flow through your hose. The smaller the kink (low resistance), the more current can flow through your hose.

When you use a small battery and try to flow more current than it can handle, you overwork it and can cause damage, as in the examples above.

Ah-What!! I think that discription will cause a lot of confusion.
More resistance is more resistance, it's as simple as that.100ohms is 100 times more resistance than 1ohm.
Where the validity of your statement comes into play is to think about poring water through a pipe. The larger the diameter of the pipe - the more water will flow through it at the same pressure.
But, even that just confuses the issue. The end result of the electrical equasion is measured in Watts. Try this simple tool to see how voltage and resistance effects both amperage and watts. Ohm's Law Calculator
Or this tool if you are math inclined

I think what he was trying to say is... Given a fixed voltage...

The higher the Ohms, the lower the Current
The lower the Ohms, the higher the Current (which fries crap).

I=V\R for those in the knowledge.

THis was posted by six and I want to repeat it.

Over-discharge is the risk with small batteries and low ohms. Catastrophic battery failures (thermal runaways, flame outs, and even explosions) can happen in three states - over-discharge - overcharge - and short.

The key words being flame outs, and even explosions. Both have happened to vapors. It's a matter of low risk and high consequence.

One more thing is the attitude of I did so it must be ok. This is the same as saying I smoked cigarettes so it they must be OK. Do you guys really believe that? It sure sounds like it.

I don't know why I quoted a post that wasn't even mine. Carry on, nothing to see here....

Basically, even if the LR atty/carto doesn't fry the super-mini ecig (even the 350 mAh ones) it's an exercise in futility. You end up charging them so often that they just get "used up" in a real hurry... and die.

As stated, I think over working the battery (over discharge mostly) is the danger. But even if you let it cool between hits, it's still irritating. This is also why everyone recommends "fat bats" for the LR stuff. Like they said above, its about AMPS (current draw). Smaller batteries just can't put out enough electrons per second and they get stressed out.

It's kind of a pain that e-cig users have to become amateur electronics gurus too. OTOH, there are plenty of people that have popped their circuit breakers at home by doing stuff they shouldn't. E-cigs are no different. You need to be aware of this due to the lack of standards in the industry (a color coding or alpha-numeric code or other such thing would go a long way to help people match stuff).

I think you would be better served using dual coil cartos over LR ones. They will still drain your batteries faster but less likely to damage the battery. Getting a higher mAh battery like the Kgo or the GLV2 would also help.

+1 on the 3.7 v. IDK about the DC vs others tho... ohms are ohms from the batteries perspective. It's the ohm rating that counts here... just to clarify the very short post. So it would depend on the ohms, not # coils. And the lower the ohms, the higher the amps, the more stressed the battery, and the more need for higher "drain rates".

The electronics probably won't fry since the super-mini batteries can't put out enough amps (a guess and average vaping). lol. The electronics used to fry in some eGo type units with LR stuff, either due to shorts, or over-amping the mosfets/switches. AFAIK, that hasn't happened in the more recent revisions (the over amping without shorting thing).

So, if I was using a super-mini, I'd stay at SR atties, or if I used lower ohms, I'd probably only go to 2.0 and not use it much. It definitely wouldn't be my main PV. And I'd be real careful not to over stress it. I'd be pretty unhappy if it vented on me while using it. This is all unverified, of course. I just doubt you could fry them (the circuits). Stressing them however, I would guess is possible, with venting as a result. Again, best guesses.

Edited my mistake. Need more coffeez before posting lol.

I think a basic explanation of resistance, voltage, current has been pretty well addressed. I'd just like to add that I've been using a 1.7ohm LR atty on the same 2 ego batts for 9 months before they went bad. And they didn't even fully go bad, just their capacity went to poop.
