I buy from RTD Vapor only--when it comes to batteries. My single coil setups have resistance of ~1.0Ω. Dual coil setups are 0.7Ω. Parallel box mods Sony VTC5.There are only a few battery manufacturers in the world who make their own "cells", including LG, Samsung, Sony, Panasonic & Sanyo.
All the other brands on the market buy the second and third tier cells from those manufacturers and re-wrap them under their own brand. These are "second and/or third tier cells" which did not meet the higher standards of the original manufacturer. In order to compete with the original manufacturers' batteries (first tier), these other companies feel obligated to publish specifications which are inflated to make them appear superior to those of the original manufacturer.
* (AW is Andrew Wan, a former Panasonic employee who branched out to create his own "brand" of batteries. He allegedly has agreements with the major cell manufacturers to purchase first tier batteries from them. Not all batteries are created equal, so AW tests these batteries for quality. The best get chosen to be AW brand, and are re-wrapped as AW.)
Do your research before you buy. Decide what battery to buy depending upon the application that you will use them.
I have nothing against what anyone wants to vape. I can appreciate anything, and consider myself fairly open-minded. I do, however, become pretty cross when people choose to push the envelope without doing enough research.
I get REALLY cross at the notion of inflated battery specs. I get that companies will do anything to make a buck. These people do not have a conscience. And it's s... like this that will be vapings downfall.
