I am a complete newcomer to vaping and i have purchased a smok tech eGo 900mah starter kit from easyvapors.com (says it can accommodate 510 cartomizers) and i purchased a Logic starter kit (300mah battery) from a smoke shop near my house. My question is, can i get the boge 510 XL blank cartomizers, at 2 Ohm's resistance, and use them in both batteries? Or do i have to get the regular 510 at 3 ohms resistance for the Logic battery and the XL at 2 ohms for the eGo? I ask this because i read that the lower resistance (<2 ohms) cannot be used in my Logic Black Label battery. I would just prefer the 2ohm XL cartomizers for the thick vapor and be able to use them in both the eGo and Logic. sorry if this is all confusing, i am confused myself. I didnt know there was a whole vaping community out there! Thanks for your help.
