I could use some info on I taste mvp. I run at 5 volts with a kanger tech pro tank 2.2 ohm tank and get around 600 or so puffs on the puff counter. Idk if Im getting the right amount I should off a full charge. I bought it slightly used from the local vape shop. It was a shop battery the employees just used it at the shop to get a feel for it for selling it. There is only two employees. So I can't imagine it got much use and I just wanted to know if the battery is still in good shape. I have a warranty so i can return it but i wanted to know what the average batt life is on it so i can return it if need b
