I'd like to chime in here and say that efest has had a pretty bad rap with a lot of vapers, despite trying to market to said vapers, particularly sub-ohming cloudchasers. the purple efest battery, as stated above, is actually a panasonic 20-amp battery with a pulse rating of 35 amps. efest also "makes" another battery, which is in fact a repackaged sony vtc4, rated at 30A continuous with a 60-amp pulse rating, at which point, may as well buy the sony rather than the repackaged and more expensive sony. MNKE's are overrated, but they also make a 30A continuous draw battery. I regularly vape at 0.15 to 0.10 ohms, but that's with a diy mechanical box mod and 3 vtc4's wired in parallel rather than series, but this is a completely different situation, because I would have a theoretical safe discharge limit of 90A. And in all honesty, a build at 0.5ohms may make bigger clouds than a build at 0.2 ohms. At that point, it's all about managing airflow *cough CCI cough* and not just sheer quantity of airflow, as well as a good inhale/exhale technique.
Vape safe buddy, don't go building pipe bombs like the guy at vapecon with a mutant clone did.
