Battery voltage; mah; atty oms; need understaning of relationships

[Vego]

In my research, I hear a lot of talk about using batteries at 3.7 volt, 4, 5 or 6 volt, ect... And I often hear it in conjunction with the ohms of certain attys.

I really need an understanding of why and when one should use a certain volt with a certain model e cig or certain model atty, and how they effect/synch with atty omhs. Do these relationships effect more than just vapor production... or vapor flavor?

Also, except for longer battery life before having to re-charge, (obvious benefit) what is the benefit of using these monstroserous, pipe-bomb looking batteries? Do we really need those things and why are they such the rage?

Thank you for any info or links you can guide me to.

Slim ecigs have limited heat because they can't use low resistance atomizers or cartomizers. They use standard resistance. LR is only supposed to be used on battery 450mah+

Depending on the voltage of the device, what ohms are standard resistance (warm) and what lower ohms are LR (hot) will be different for each voltage.

A 3 ohm atty on a 3.2v battery is slightly warm. A 3 ohm atty on a 5v battery is hot. A 3 ohm atty on a 7v device might just pop and die.

So the lower the ohms are relative to the voltage, the hotter the vape and the faster power is demanded from the battery. Heat enhances nicotine's hit. But if you go too low, you can damage lots of batteries if their protection circuits fail to stop you.

Exception re ohms and heat - the above is for single coil devices. There are also dual coil devices which draw as much power as LR but are firing 2 standard resistance coils. So due to the power draw they should only be used on big strong batteries, but they make more vapor rather than being hotter.
