New coil - tight airflow and hot battery

[antony73]

I have recently begun building my own coils. Not because I think boxed coils are a bad thing, but just because it's just another fun part of the vaping hobby.

I've built 2.3/2.5ohm coils for a Protank2 and EVOD.
2mm wick
1mm flavor wick
32gauge wire/6 wraps

The Protank/EVOD draw is usually very airy, but with my new coils it has become tighter. I have cut the wicks to a minimum length so as not to obstruct airflow, but it has become tighter. Though no way near as tight as a CE4.

The other thing I've noticed is that the top part of my Vision Spinner is becoming somewhat hot. Not so hot that it can't I touch it. But warm to hotish... The MVP seems fine, just the Spinner. The Spinner is ok with boxed coils, which leads me to believe the issue is with the coil. The coil runs around 2.4ohms and I set it to 3.7v.

This isn't a problem for me, but I'm worrying that I may be doing something wrong. Safety n' all.

Does anyone have any ideas?

Thank you!

It would seem obvious that the new coil setup is somehow restricting the airflow. Maybe it's set too low towards the air hole? As far as the heat, so long as you are confident of the resistance of your coil I wouldn't be too concerned. Most of my clearomizers run hot enought to be obvious to the touch after a few healthy vapes.

That's a good point Miata GT. Thanks for that.

You're probably right, I set the coil down at the bottom, on top of the air hole. I had wondered how far down I should set the coil, and decided to put it way down. I'll re-coil midway and see if it makes a difference.

But thank you, I hadn't at all crossed my mind to set it higher above the air hole.

Just put together two new coils placing the actual coil a little higher and it seems to have done the trick. THANK YOU!!!

The Spinner is still getting a little hot, but maybe I'm pushing it harder with the new coil. See how it goes.

Thanks again
