I would go with the advice of the chunkmeister ...this guy has become my vape guru and has led me through all the options of batteries and making my own juice...and has started to mod his own Cartomizers...and posted his vidoes on youtube ..as im no good at DIY i might get my begging knees and ask him to make me a couple
Keep a eye on this guy on youtube i bet there will be more to come in the future.
Get away! I'm no guru - I just like to get stuck into a topic / pasttime when I start. It just takes a lot of reading here.
I've just posted my first video - I now feel pressured to make another - ya git!
