Okay I have been lurking this forum for several months now, and can contribute my success for putting down the analogs to my brother who has been vaping for almost 2 years, and this forum for the wealth of knowledge and the excitement it has instilled in me to try new things while satisfying my tinkering needs the most I can being budget limited. And it is my first real problem that I can bit seem to work putt that leads me to my first post as searching has turned up empty...
Equipment is a vivi nova, and 3 ego 650ma batteries (non twist, the ego twist was not around to the best of my knowledge when I first tried unsuccessfully to switch in Jan of this year) the problem exists with all 3 aging egos.
Every coil I make with 32ga kanthal errors out on the ego, same coil design with nicrome works without issue. Problem is as I was nearing the last couple feet of nicrome 34 I decided to try kanthal 32 when it was time to restock, planning on a rba genny mod as soon as the budget allows. After a bit of a learning curve figuring out coil size, wick thickness and what not I got pretty good at making uniform coils with nicrome ranging from 3/4 wrap 1.7ohm to 6/7 wrap 2.9ohm coils using cotton strand wicks. The last 10 or so I have made out of nicrome all fire beautifully. And then the kanthal comes in the mail... Same technique, cut off a section of wire, heat it with a lighter, wrap it around a curtain hanging hook squeeze the coil tighter together to allow it to slightly spring back making for a very tight coil, unwrap the last coil on each side, double up the leg to the coil and twist very tightly, rewrap the last loop (whereas most of it is now doubled) back as part of the coil. Now the wick, get it to half the desired thickness in the case of what I am using is doubled over twice, then use another single piece of thread with a loop at the end to put the wick into, then I pull this thread fishing the wick through the coil, then re adjusting coils to make sure it is not shorting across the loops. Ohm out the head making sure no short to the body exists then put the head on the post, check the ohms at the bottom of the post to make sure the head is not sorted to the body of the center post is some way. Everything still good at this point. Screw it onto 1 of 3 different batteries and always the same the power button starts to light, less than half a second later it goes out and the battery stops responding to button possess until I plug it into the charger for couple seconds I assume resetting it.
I have 8 different heads ranging from 1.7 - 2.9 all doing the same, put the nicrome head on and it fires right up. The kicker is any and all of these heads work just fine on a vv box mod set from 3.1 - 5v. Take my current nova off my box that is being powered by either a pair of aw imr 14500 or protected trustfire 14500's both sets work, and the trustfires have not tripped the protection circuit. Just seems that ego batteries or thier protection circuit more likely... Whatever it is I am at a frustrated loss for a solution other than to drop the ego batteries and get her a good tube mod, but that just isn't in the cards right now.
Sorry for the long winded post, but wanted to illustrate that I am confident that its is not my coil building/shorting issues, I worked that all out in the first 10ft or so of nicrome that I had to toy with.
Another note, the center post on the nova has been slightly filled down due to is stock shorting out, whereas my nova did not need this fix, neither base works with a kanthal coiled head, both work with nicrome tho...
Any suggestions would be greatly appreciated.
