So when I bought the starter kit, it came with a 650 ego battery and a 900 ego battery. I kept the 900 for myself and gave the 650 to my dad. It seems hes burnt out the 650 in like 3 months lol. I need to get him a new battery and don't really want to go through volcano again because I feel they may be over priced. Any store/website recommendations and setup recommendations? Been enjoying the ego's with clearomizers but I think I want to get the kanger T2's for him. They seem easier than the tank+cartomizers he has right now.
