Atomizers vs. voltage

[martha1014]

I am not quite sure which atomizers to use with which voltage. I can use a regular atomizer on 510 or regular ecig voltage. I can use a regular atomizer on 3.7 or I can use a LR atomizer on 3.7. I can use a HV on 6.0 volts. Which atomizer can I use on 7.4 voltage.

Which produces the best outcome and what usage will enhance the life of an atomizer.

There have been so many post regarding this someone can get totally confused. Can someone explain all of this to me.

For 7.4V you probably want to use an atomizer with 5+ ohms of resistance. You can determine how much power you're getting using this formula:

P = (V / R) * V

So at 7.4V with a 5.2 ohm atty you would get (7.4/5.2)*7.4 = 10.5 watts of power

A 3.7V device with a regular 510 atty (2.3 ohm) would give you 6 watts of power.

An eGo (3.1V) with a regular atty only gives 4.2W of power.

You'll need to experiment to find out the power level that suits you.

I'm not sure which combination would result in the greatest life expectency for an atomizer.

Digs is pretty much right on.

There are low resistance, regular, and high resistance 510 atomizers.

The key is to stay in the 10watt range. There is no sweet spot as far as voltage goes, its all about wattage.

I run 2 LiFEPo4 123a 3V batteries in my Silver Bullet. On a regular atty, I'm getting:
(as tested on my meter)
Batteries right off charger...
7.9V unloaded
2.2Ohm 510 atty
5.2V loaded
(remember that you have to use the loaded vlotage, not the unloaded voltage of the batteries!)

(5.2/2.2)*5.2 = 12.2watts So I'm running a bit over the sweet spot when the batteries are fresh off the charger. But, after an hour or so, the volts drop and the wattage falls right into the sweet spot. I've monitored this several times.

So...
1. If you are using 3V lifepo4 3V batteries, use a regular atty (2.5-3 omh).
2. If you aren't stacking batteries, for example you are using an 18650, use a low resistance atty (1.5 ohm).
3. If use you two 3.7 batteries, I'd go with a high resistance attys (4.5 ohm).

I hope this helps.

Here we go again...

Here we go again...

4.785v with a 3.05 ohm atty or carto for 7.5 watts.
I thought that was the new sweet spot?

There is no one "sweet spot" for everybody. Some people like higher wattage, some like lower. You can use this chart to figure out what works for your preferences.
