Yeah found it on Madvapes. I got heavy into this in march, the first week of owning my first one being a ProTank 2, I was taking apart the coils, wrapping the coils with out a ohm meter with in two weeks already, guesstimating the circumference and also the wraps for the resistance it would put out. I started using cotton. Ripping out all the mass produced Kanger heads, Then went to 29 gauge. Later, recently last month or so got a Kayfun clone and a ohm meter. I checked my wraps of my old protank coils just for fun, they where dead on what I thought the ohms were. Anyways, moved forward had a ego twist with a kayfun, but we all know about ego-s good for on the run batteries if well your really into it, you aren't using a Ego on your main tank or RDA. So I just got this first "mod" Smoktech SID and going deeper. Long story long, yeah I checked the site we all know of that's massive site aka Madvapes I didn't originally see the info, but didn't know on the info on batteries for the devices themselves for the highest performance to move forward. Thanks to RIP Trippers, he's like me can't stop messing with anything and wants it perfect. Anyhow found the info thanks for the responds.
