LR vs SR coil and battery life.

[MrAnchovy]

Hi everyone,

I have a question about battery life with respect to standard resistance vs low resistance coils. If I normally vape at 3.9v on a 2 ohm resistance coil and then I change the coil to say a 3 ohm coil and run it at 4.9v to get a similar experience, would I have more or less or the same drain on the battery by running at a higher voltage with the 3 ohm coil?

Related question:
if I have a Variable Voltage mod that runs up to 6v, is there any advantage or disadvantage to running low resistance?

As always, grateful for any help,

MrA

From what I understand, batteries are more efficient and will have a longer life if you tend to run them closer to their native voltage (usually 3.7 volts for single battery setups)

To answer your last question, using the Safe Vaping Power Chart using a low resistance atty (< 2.0 ohm) you may begin to taste burnt juices above 4.o volts. Higher voltage than that you are in the red zone.

If you used a 3.0 ohm atty you could take your voltage up to 5.0 volts. If you feel the need to use 6 volts, you'll need a 4.0 ohm atty.

There are those vapors who debunk these charts, and use low resistance attys at extremely high voltages. Frankly, I don't understand the need to use a PV as a power torch. What ever keeps them off the smokes?

If you want battery life, just get a mod that'll hold an 18650 battery as far as the difference between the vapes of low and standard resistance, i think 3ohm running at 4.9 volts is a bit hot. 3.9 volts on a 2ohm is a slightly cooler vape. I think of ohms as a track and voltage as the power of the car. Shorter the track, the less power you need. The longer the track, the more power you need.

Using ohms law:
3.9 volts and 2 ohms - 7.6 watts and 1.95 amps
4.9 volts and 3 ohms - 8.0 watts and 1.63 amps

The low resistance set up will have more amp draw on the battery, and be a cooler vape. The higher resistance will be a warmer vape, and less amp draw.
So in theory the higher resistance/higher voltage set up means less drain on your battery. There is debate about that sometimes - but its generally accepted that low resistance causes battery drain quicker than standard resistances.
