I am kind of asking myself that now also, but 3 of the 650's I use all the time charge one per day, I have them numbered and rotate there usage. the other 3 will be their replacements when they are dead. The 650s are my portables, the 1000mah bats I mainly use at home because when I am home I vape like crazy, and they last longer. Now I have this evic and now this thing one charge will last 4 days, so now I have this thing that kind of changes my battery usage at home, but I won't run out of batterys very soon.
why so many batteries?![]()
