How many batteries do you have for Normal size V2?
I have 7, and I have a system to ensure long life of the batteries.
I use 1 battery per day. That's not forced, one battery just lasts me all day. Each battery is numbered 1-7, and I rotate them out each day of the week. This way, each individual battery gets charged and discharged one time per week.
7 batteries... damn haha i need to step up my battery game.
I have two AW IMR 18650's for my provari that I rotate on my pila. Both are a year old and still last all day.
