I just recently purchased an SID VV mod, usually i vape at 6v with a 1.5Ω dripping atty and i am running my batteries down really fast, as far as i know you can't use protected Li-ion batteries and must use IMR's, correct me if i am wrong. Unfortunately i haven't found an IMR battery with a capacity above 2250mAH, which is a measly 250mAH above what i am already using, does anybody know of anything with higher capacity?
