Sulti, I'm not sure if I can help, but I'll try.
What type of stranded battery are you using?
I would reccomend a plain lithium ion battery. I never used a stranded type battery. I think the plain IMR lion are best for e-smoking.
On your VV , quit pumping it! Thats what makes the Brunt taste. If your VV puts out 1000 watts, it may brunt the coil amigo.
