i'm curious if there are any disadvantages to using low resistance cartos? new to cartos, and with my first order i got a few low resistance (2.0) and a few standard resistances (3.0). i noticed that with the 2.0 cartos set at 4.0 volts and the 3.0 cartos set at 5.0 volts, i get the same flavor, but since the low resistance cartos require less voltage, my battery lasts longer. do the lower resistance cartos burn out faster or anything? why would someone choose high resistance over low?
advantages/disadvantages to low/high resistance cartos?

I'll let people with a better handle on the amps/ohms/voltage thing take care of that end...but here are a couple differences I've noted:
a) I use non-variable Egos pretty frequently as a grab-n-go, and for me, they don't cut it on the 2.4's, especially as some of those 2.4's are actually 2.7.
b) I can TASTE the difference - with SOME juice, at least, even when I'm using a Variable Wattage device that adjusts for the coil resistance, I've found a flavor difference! So there's the answer I think - some people find a superior vapor/flavor result with higher resistance and higher voltage.
Overall, I lean the same way you're thinking - I buy 1.8 ohm coils (which tend to come out of the box at 1.9 or 2.0).

Correct, according to atomizer power calculation P=U2/R, power for 2.0 is 8w, while power for 3.0 is 8.3w, they're very similar(0.3w is neglectable), it's same w what u felt by urself.
But as to last time for batt, suppose both output mah is same, for example 650mah, so total energy is diff, Energy=650mah*Voltage, Energy(2.0)=9,360J,Energy(3.0)=11,700J.
Lifetime each circle for T(2.0)=energy/power=1,170s, T(3.0)=1,409s (continuous vaping), so 5.0V lasts longer.

I personally like the Boge XL LR 2 ohm but the Smok Dual Coil (seems to run around 1.5 ohms) are fine too. I run at 8 watts and I like the flavor/vapor and carto lifespan at that power. I found that I burned them out faster and frequently got a burnt taste above 8 watts. The only difference that I find with higher resistance coils is that they seem to take longer to heat up. YMMV.
I know pbusardo (think it was him at least) posted a video about the basics of volts/ohms/amps and whatnot, and that LR cartos/tanks/clearos/whatnot don't necessarily make your battery last longer.
LR cartos are great for non VV/VW devices, since you don't have the power to go and get the optimal vape from say a 2.5+ohm carto.

Could not quickly find the info on ECF, I know its here,
just can't remember which room I saw it in...
A link to the folks at Discount Vapers on LR/HV:
Undestanding resistances, LR and HV
"The typical resistance of LR cartomizers is 1.5 ohms. Vapers routinely use such 1.5 ohm LR cartomizers on 3.4V eGos (7.7 watts and 2.3 amps) all the time: excellent vape intensity but the life span of this tye of usage is much shorter due to the intensity.
There is no physical danger in such high amps, nothing blows up. Its just that 1.5 ohm cartomizers die faster than standard (or high) resistance cartomizers."
