coil craziness

[Cyberninja]

So I went to my local vape shop and bought an Itaste svd and a kayfun lite. All excited to try my first rebuildable, I went home and built my first coil...I could get an ohm readout...but it wouldn't fire on either my Itaste svd or my mvp2.0. I tried several times and got the same results, so I gave up for the night and ordered a Tobh atty. When this arrived I tried a build, and got the same result...it'll register the ohms, but will not fire or heat my coils. So I started to wonder if my batteries were too weak to push the low ohm builds. Do I need to buy a monster battery or change my coil wraps? I ordered some 24 g kanthal, but I also was given some 28g wire, and some twisted wire to play with. Suggestions!!!
thanks!!!

what resistance (ohms) did the coil read at?

You need to be above 1.2 ohms to use those devices I believe.

My first suggestion is to understand your equipment. What was the ohm of the coil you tried to fire on your MVP & SVD?

You should get an ohm meter to know the exact (+/- error) resistance of your builds. The MVP will not fire anything below 1.0Ω for most, but only functions properly (adjustable) at 1.2Ω+. The SVD won't fire anything below 1.2Ω. What are your builds reading?

This.

See what you get with the 28 gauge.

 

[Cyberninja]

my mvp and svd both said .5 ohms...I wasn't aware that they would only push 1.2 ohms. So I need a different coil build, and a different battery setup to handle low ohms. Also considered buying an ohm meter, but figured since both devices would show the ohm rating that I could skip it. Noted...and thanks, I'll get one. can anyone suggest a mod that can handle a lower ohm build? There's so many to choose from, and each looks better than the next

the 24 is too much for those devices but the 28 is just perfect. try aiming above 1.4ohms and it will work great

 

[Nytebreed]

MVP must be >1.2ohms
SVD must be >0.8ohms

The protection circuits are kicking in.

I was running my partiot on my SVD for a while at 0.9ohms.

Well....let me be frank. Slow down! You need to do a whole lot of studying before you think about a .5 ohm build. You don't want to do it on a Kayfun. Build a 1.5ish ohm build and you and your mods will be happy.

So I rebuilt a 1 ohm coil and put it in my toby atty...and success!!! The throat hit nearly knocked me over...the draw was airy as hell...not nearly tight enough for my liking, and I got negligible vapor production. Also the coils take longer than I like to heat up...grrrr...always something.

I use a Kayfun on an MVP2 as my all day/work setup because of the battery life and tank capacity. I have found that 1.3 ohms is the perfect amount of flavor and vapor for myself. I use 28g kanthal with 8-10 wraps on a 5/64 drill bit.

Wow.never knew that calculator exists.

can anyone suggest a mod that can handle a lower ohm build?

I have the eVic Supreme and it will fire down to .5Ω coils but there are other regulated mods that will do the same.

the draw was airy as hell...not nearly tight enough for my liking

The draw on RDAs is typically airier than RTAs so that you can keep lower ohm coil builds cool. I always do lung hits on my RDAs and appreciate a very airy draw. You get more vapor production with more air as well.
