I'm pretty stoked to hear you so confident in the stacking [emoji16]! Since this is my 1st go around with removable batteries I, like many others I'm sure, took PBusardo's as the king of all vape knowledge (lol) and was terrified to try. But after hearing y'alls advocacy I'm definitely going to hv to try that out. Although I must admit, i put one of the Panasonic 18650's I got in each new mod (svd 2.0 & zmax v5) and hv been vaping steady all day on zmax and even since yesterday on svd 2 and the charge is still completely full!! Pretty impressive! That's not to say they won't digress over the long haul tho. However I will be taking your advice and grab a couple 800mah 18350's!No such thing as a silly question. There are seasoned veterens that don't understand when stacking batteries works best. IMO I got the zmax to work in mini mode. I like small mods. I got tired of changing out 4 batteries a day pretty quickly. I got a couple of 18490/18500 and they were better, still didn't last a whole day, which also wore thin.
Then I came in here and learned about stacking 2 18350's and the sea parted. I kid you not. I had a whole new vape experience that quickly became #1 (including my provari). At the MoVapes price I've boughted 3 more, 2 for friends and 1 to backup my backup. I have tried explaining why stacking is so cool in the zmax (not all mods work well with stacked batteries) and quite frankly, it doesn't work. Stacked batteries have been abused in the past with mods that were not designed to be used that way. The Zmax was designed for them. I think it's our little secret in this corner of the web.
So IMO, you'll either want the long or short use of Zmax. I wouldn't bother getting a middle sized battery. At least try it out first. You may want to sink your money into a nice atty or a backup Zmax instead.
I haven't noticed much difference between AW and Efeast. I think the main difference is where you buy them so you don't get caught with rewrapped counterfiets. No ebay, no ali ....'s, etc. RTD, Wong has an order thread on another forum, Illum supply (or something, they just changed names). etc. Know your source.
I'm loving the Zmax BTW! Thanks to all who suggested it to me a couple weeks ago! I honestly can't tell much of a difference between it and the svd 2 as far as vape quality. For me it largely depends on my tank. I got a nasty batch of butterscotch and tainted my aerotank so until that's all outta there I'm preferring which ever mod has my nautilus lol.
