I seriously doubt that it will be a problem to buy PG, VG and flashlight/power tool batteries. vaping is just a small part of the market for 18650 batteries in particular. PG and VG are both common food additives that have a plethora of other uses as well.And batts, that's something that brothers me, if I get say 10 batts but not being used I suspect I'll have to still keep them charged
