There's some information that is missing from your post. You don't mention what wire gauge you are using. Also, is 2Ω the reading you were expecting?
To me, it sounds like you may have some kind of connection issue causing a high resistance reading that shouldn't be there. If you have a 1Ω build, but the mod is reading it at 2Ω, it will fire at a high voltage causing the hot/burnt vape.
Coil placement can also affect vape temp. Got some pics of your build?
I did neglect to include the wire gauge used and it was 28 which was the smallest gauge I had on hand.
But I broke it down, cleaned it up and used one of the coils I wound with the wire that came with the tank which seemed to be in the 22/24 gauge and it came out to 1 ohm.
I dry fired it and did a better job of the squeeze to get the coil firing across the complete coil...something I did not do on the first build. Beginners fumble!!
Then I wicked it with a longer/thicker wick...Japanese organic cotton and made sure I had the cotton all the way to the bottom of the tank to the juice channels...
I then soaked the wick to the extreme, fired and everything seemed to be fine.
put it back together, filled it and was immently rewarded with a near perfect vape.
I love this thing as it is now...but know it can give me a little more of the vape I'm looking for..which is a little cooler while not draining my batter so quickly. I'm using a HANA 30Watt clone with a single 18650 and I'm only getting about 50/60 good draws so I need to address these two issues and I'll be a happy, happy vaper!!
I know this is going to be my tank of choice until someone comes up with a better one that has the nice air flow adjustment and the top fill that works so well for me.
I have to say this again....This is my first RTA...so I can't compare it with any other. I just know that I did not want a leaky, bottom fill through a screw/plug type RTA....and so far this tank fits the mold of what I consider a good deal!!
Thanks for the response.
