question about kanger k2 and different resistance coils

[NLDV]

Sorry, I can't post in the other forums yet..

I'm using a vision spinner 1300mah and want to know which coil resistance is better for my t2 clearo?? Which one gives battery life?

I tried a 1.8ohm already and now a 2.2ohm. Does the battery drain faster when using a higher rated ohm coil, seeing as I've got to turn the volts up for the higher rated coils? Or does it not matter? I'll just use 1.8s if they give better battery life... they worked great so I may not need to use a higher ohm.

Thanks

It depends on the voltage you set for each resistance (OHM) value, because that determines the amps (draw) on the battery. It's the amps that determines how quickly the battery charge is depleted. For the Kanger T2, I haven't seen much difference in the battery life between the 1.8 ohm at around 3.8v and the standard 2.4 ohm at around 4.4v.

I... see? I'm not sure what you mean.. This sounds to me like the higher the volt, the more amps are drawn period..

Sorry about that. Let me try to explain it with a bit more detail. I like to vape at around 8 watts, and the formula to calculate watts (power) is voltage squared divided by resistance. Essentially, it works from Ohm's law (see link below):
Ohm's Law Calculator

So, to get 8 watts of power using different resistances, I need to set different voltages which in turn draws differently on the battery (amperage). The higher the amperage, the harder the battery works to provide the power needed, and thus the shorter the charge cycle lasts:

1.8 ohms (resistance) @ 3.8v = ~ 8 watts (drawing ~2.1 amps)
2.4 ohms (resistance) @ 4.4v = ~ 8 watts (drawing ~1.8 amps)

Between the first two examples, there is only a ~.3 amp difference, so the battery charge cycle difference might be minimal but the higher resistance would allow the battery to operate a bit longer between charges. How that translates into usable hours on the battery depends on how often you use the device (light, moderate, heavy), and a few other factors.

Does this make more sense? If not, let me know and I'll try to explain it better.

ok this makes more sense..

funny I had it backwards, its actually the higher ohm coil that gives slightly better battery life, although probably not a big enough difference to matter between different coils.... My 1300 lasts all day and I just charge it overnight, never had it die on me yet..
