LR Atty question

[Ragamuffin]

Hello. My question is: I keep reading that Low Resistance Atomizers are only supposed to be used on batteries that are at least 440mah or higher, AND that they make the "3.7Volt vaping experience feel like it's 5volts", then which 3.7volt batteries are 440 mah or higher?

Thanks

The easy answer would be just about any mod battery except for the 10440s. Also the eGos have a high enough mah rating to use them on.

Basically any mod...or an eGo.

The capacity of the typical batteries is too low, that you will kill the batteries so fast its not even worth it to use LR on them.

Thats it. It isn't even advised to use lithium ion batteries with LR attys. IMR, or high drain batteries, are your ticket. They supply the power needed at the rate required better than li-ion can. When you use LR atomizers on a li-ion battery, you will ultimately ruin your battery because it is drawing too much power (more than it should be giving). IMR batteries are meant to supply gobs of power, making them your perfect match for LR attys.

Ummm, not exactly... Just check the max discharge rating of your battery. Often listed in "C" and sometimes amps. Typically Li-Ion batteries will have a max discharge rating of 2C. Depends.

So. Nominal voltage of a Li-Ion cell is 3.7v and they charge to 4.2v. Let's use 4v. Typical LR atomizer resistance is from 1.5 - 1.8 ohms. Throw in maybe 0.2 ohms for springs, switches and stuff. 4v through 1.7 ohms and you're going to be trying to draw about 2.3 amps? A 14500 is usually about 900mAh, 2C would be 1.8 amps... you're getting in the ball park. IMRs are like 8C to 10C? so no problem there. A regular 14500 would work but it would be a little hard on the battery and you wouldn't get the full performance from the LR atty. A regular 18650 with about 2400mAh would probably have a max discharge rate up around 4 to 5 amps so that would do just fine as well.

Reason not to do high voltage like 5v or 6v is that, with the low resistance, you're going to be running a really large current through those. I would expect the atomizer's life to be brief at best. Like 3.8 amps. 25 watts is a lot of heat...

It really doesn't have anything to do with the battery chemistry.
