The lower the resistance, the more current will be able to flow through the carto (or atty) so the hotter it will get. Also note that the more current allowed to flow, the more rapidly the battery will discharge. I don't know what kind of battery you're using but it needs to be above 450mAh current capacity to run LR (less than 2.5 Ohm resistance) cartomizers or atomizers so it doesn't discharge too rapidly.

Hope that helps... Happy vaping! :vapor:

LR's will drain your batteries faster than SR's and should be used on batteries with at least 900mah.
You get a warmer vape and more vapour and TH with LR's on a standard 3.4/3.7 volt device.

SR's are better on vv devices 'cause just cranking up the voltage will give more heat TH and vapour.

There may be more differences but I think these are the main ones.

If the 1.5 is a dual coil and you're using a 3.4 or 3.7 volt battery you may not be getting as much punch from it as one might expect either. The 1.5 dual coils are constructed with two 3.0 Ohm coils wired in parallel, giving a total resistance of 1.5 Ohms. That's okay but in order to get much heat from those coils they require a higher voltage. Some vapers are perfectly happy with them on a 3.4 volt eGo or 3.7 volt whatever, but personally I get much better results with Smoktech's single coil XL 1.7 Ohm cartos or Boge 2.0 Ohm.

You need to learn this easy formula for determining watts based on volts and resistance (ohms), because most juices vape best at around 8-10 watts with a single coil cartomizer.

Volts x volts / ohms = watts.

If you have a 3.7V PV, you want a low resistance single coil cartomizer/atomizer, usually a 1.5.

So: 3.7 x 3.7 / 1.5 = 9.12 watts.

If you run a dual coil at 9.12 watts, each coil gets only half of that = no good. Flavors will be muted, vapor production will be just OK. The coils need to be at a proper temperature to fully vaporize the juice and bring out the flavor.

Just for remembering which end is up (so as not to hafta break out the "math" brain cells), keep in mind that resistance "resists" the flow of current, so the more Ohms of resistance you have, the *less* current you'll have flowing. Less current = less heat. Lower resistance allows more current flow; more current = more heat. (I think I'll go into my kitchen & make some Ohm slaw!) :D
