Traver- you show quite a bit of knowledge here, so let me ask you frankly, what is your most reliable e-cig battery, regardless of style?
There are so many batteries out there I can't possibly answer that question and I have a very limited experience compared to some people. I am assuming you mean the moderately priced Chinese batteries. If you really want to know about batteries read this thread where people who know something discuss them. It's a lot of reading.

For low a price the Joye Ego with a PT and a 2.5 ohm atty or carto.
A 2.4 - 2.6 ohm will give about the the same vape as a 2.8 - 3.0 on a KR808. Most people go around and round about batteries. As far as the vape goes it doesn't matter as long as it can deliver enough power for your needs. All the battery does is deliver power. It is the carto and the juice that determine you vaping experience.
For a mod one of the ProVapes.

A big part of my consideration with a mod is reputation, longevity and to be able to replace the actual battery. Five to ten bucks for a replacement.
The ProVari will be my next battery.

These may or may not be the best but they are the ones I know well enough to recommend. Next week it may all be different.
Personally I use a 900 Xpower instead of the Ego. Same vape but lasts longer. I don't recommend it to people though because of the odd thread. You have to use an adapter for most of the cartos out there.
