Very nice buddy, how have you been? I've completely switched over to Mechs and unreg. I'm so happy with them. I hated one mech and let it ruin my opinion of single battery mods. That and the kbox mini. The mini has fucking horrendous battery life.Like I have explained in another thread not too long ago, the iJoy 5-legged 20700 only really shines in a dual series mech IMHO. Another thing about this battery is that it is a 30 amp battery so you can build at lower ohms compared to the VTC5A─in order to compensate for the fact the 20700 doesn't hit as hard... thereby offering different coil building options to explore (not necessarily always better ones, but still).
On a dual series mech (i.e. on my brass Vaperz Cloud XXX equipped with the separately sold extension tube as well as with the separately sold bottom section that uses the newer Comp-S switch as opposed to using the older VC Tech switch) at .28 ohms─dual coil fused claptons using Kanthal cores─I can vape on the iJoys pretty much all day without me having to change the batteries. This cannot be said about using dual VTC5A in this same setup by using the accompanying 18650 plastic adapter sleeves. Also note that different rewrap companies can use different grades of batteries so... same battery, different grade = slightly different performance. Efest have been notorious in the past for having lower grades and then selling them at above average prices, albeit they have bettered themselves according to Mooch. Lower grades are not rejects, but they perform a little worse so then why should we be paying extra.
Here's a quick/dirty picture of the .28 ohms coil build that I am referring to... I have it in my Purge Mods Head Shot RDA:
