i bought the standard 3.6v batt from altsmoke when i bought my silver bullet, it hasnt come yet, but i have been reading that a lot of people use a 6 volt battery instead, claiming it vapes better faster. did i waste my money on the 3.6 volt battery, and if i want to test a 6 volt, can i use disposable duracell 123 batteries from my flashlight? what do you think?
