Hi all! Ok well I just got a vtube (regular size) from apollo ecigs. They were out of stock for extra batteries so I wanted to order some more. I am moderately confused on this whole battery topic. This comes with an 18650 2200mah battery. I understand AW is the best bet. However I see that some sites like vapor king sell these but they are unprotected. So is that what I am supposed to get? Unprotected? I found some on lighthound.com that say they are protected. I just don't know what this one is that came with it because on Apollo's site it doesn't say if they are or are not. And I don't know if the charger that came with it can charge either kind. I was thinking of getting protected batteries as it sounds like they don't have an issue with overcharging but then again some chargers designed for unprotected chargers say they prevent it from being overcharged. Anyway like I say, moderatly confused here and somewhat shocked to read the battery descriptions that say never leave these in the charger unattended. Good grief!
