There is
no one best PV (
juice-fed or otherwise) for every vaper. My
Wonderful World of Mods describes the juice feeders in
this post. You'll see that they range in price from $45 to $135 ... not counting the GG Telescopic Storm with AVS ($239, but that is not exactly bottom fed).
The highest mAh battery used in mods (at this time) is the 18650 (~2500 mAh). You'll see that the
Ali'i and
P Woodie Feedie use this battery ... and, I believe, the
Reo Grand will. They certainly will "last all day" ... and night ... and then some.
Mods using the 14500 battery (~900 mAh) will last all day for all but the heaviest vapers. The much less expensive
Wetbox uses that batt.
The "best" atomizer certainly is in the eye of the beholder (or throat of the vaper). The 510 is the most
popular. The 801 has always been
my favorite ... although this Cisco LR 306 atty I am vaping now is bewitching me (and many other vapers). But many people reading this post will scream that I haven't mentioned
their favorite.
In general, on the 3.7V batteries used in those juice-fed mods, you'll probably want to check out the LR versions of whatever atomizer model. And not necessarily 1.5 ohms. ~2.0 ohms puts less strain (i.e., amps) on the atty, while still delivering an intense vape.
