All I have now is a regular evod starter kit, and I've been thinking of getting a "Fancy" battery but don't want to spend money only to find out it wasn't worth it. A friend is offering me a "Tesla" I believe its called for $50 which he says is half of what he bought it for, but what is your recommendation. What I want, is a battery that's easy to keep clean, and not a hassle to have in my pocket, nothing that has small pockets that will fill with gunk or juice and cause hits. I should also probably mention I don't use nicotine in my juice, and what I want is as much flavor as possible, I would also need a new tank I believe so, yeah. Solid flavorful hits, whats my best tank and battery options?
