I have a Terminator RBA, Smoktech Magneto, running Panasonic CGR18650CH batteries. I had posted in a separate thread that I was a little disappointed in the battery life that I have been getting. Around 3.9v my vapor would pretty much disappear and I was having to change batteries. I had been wrapping my coils for around 1.2-1.5 ohm. It was suggested that with that ohm range, I was only using around 15% percent of the battery and I should try a 0.8 ohm coil and would likely be able to use the full usable range and get the battery down around 3.6v before needing to swap.
So, I got myself some 28 ga Vapowire A1 Kanthal.... and I've been using 30 ga .999 silver wire for my NR. I wrapped up a new coil and I'm seeing some strange things happening. First thing is.... when I newly wrap the coil (and I saw this with 30 and 32ga kanthal as well on previous rebuilds) it will test out higher than it should be. For instance, the coil that is currently in it, I used 1 3/4" of 28 ga Kanthal.... which should be somewhere around .8 ohm I would think. When I finish wrapping and get it attached to the Terminator... it reads as like 1.8-2.0 ohm. Then I screw it down onto the Magneto and dry burn to check that the coils are glowing evenly, pull it back off and test again and it reads as .9 ohm. So I go ahead and use it that way.... use it for awhile and vapor starts to get weak, so I check the battery... it reads 3.88v. Pull the atomizer off and check it, it's reading 1.8 ohms. It also seems like it takes the 28ga wire a long time to heat up.... I have to hold the button for a couple of seconds before I ever start to take a drag or I get hardly any vapor at all. I can actually hear the difference from when I first hit the button, till a couple of seconds later when it's actually hot.
What am I doing wrong here? I don't understand how less than 2 inches of 28ga Kanthal could possibly get up to 1.8 ohm. I have tried to meter it before I wrap, but I'm never able to get a good reading with the probes on just the bare wire. I also don't seem to be getting many wraps.... I'm using 2mm Ekowool wick, with an additional flavor wick on top, and wrapping as tightly as I can, and ending up with a 4/3 wrap. Any help would be appreciated.
