Not what I was expecting...

I vape using a Kangertech Kbox mini and Toptank Mini. I have never used the stock coils, instead opting for the RBA deck. I use 28g kanthal wrapped around 3/32nd drill bit. I'm a creature of habit and always use 5 wraps, no spaces. This always creates a coil of roughly .75-.85 ohms.

This morning, I wrapped a coil that was spaced more than usual. I screwed it down, read at .81, and dry fired it so get it hot and pressed it together to get rid of the spaces. I accidentally pressed the fire button while my tweezer was on the coil. It basically melted at the leads. Oh well, wrap a new one.

I wrapped the new coil using one of the long legs I snipped from the first coil. Same thing, 5 wraps. I'm not sure where my head was, but I installed the coil upside down (for me). I usually install with the coil above the legs. This time, the legs were on top. I didn't think it would make a difference, but when I read the resistance, it was .54 ohm. Double checked it on the ohm meter just to make sure I hadn't screwed up my mod, but it read the same.

I don't understand how I'm getting such a low resistance. I started with a short length of wire ~5in and installed it differently but in my understanding of resistance, that shouldn't matter....

As a side note, the flavor and vapor are incredible, but my juice is a 6mg so it's a little harsh at a .54. Any thoughts on how a coil that should read .8 is reading .5? Thanks in advance!

Could be the length of the legs is different due to the fact that you installed it differently

I would remove the .54 coil.. Try it again see what happens. Repeat usual process to get the desired result.

I don't mind the half ohm coil. Once I got used to the increased throat hit, the flavor is much better! I was just wondering if there was something I was missing that caused an unexpected drop in resistance.

Would be a good starting point.

Only thing I can think of that would lead to that big a drop for same number of wraps... Is coil touching somewhere. Length might account for a few hundredths of an ohm but not 3 tenths. .3 tenths is like 1 or 2 wraps worth of different.

Could you have stretched the wire when reinstalling it? That can play with the ohms as well

The coil that came out to .54 was a new coil that I wrapped from the long leg of the first one that I managed to melt So it's possible I stretched that leg when installing the first coil. I feel like stretching it would increase the resistance though, by making it thinner in some minuscule way.

Either way, I hope this coil lasts a long time. I just refilled the tank with one of my favorite juices and I'm tasting notes I've never tasted before. I'm confused but thoroughly happy with this weird coil.

I use SS316 26ga. 5 wraps on the little blue screwdriver that came with the unit / tank. Ohm's out at 0.3.. I have no problem Vaping at only 30w tops.
