Soooo I got my Joye510 starter kit from The Vapor Pro yesterday and I unboxed it,charged one of the batteries for eight hours as instructed. Went to vape and my ecig has a burnt flavor to it,I couldn't say whether it's the atomizers or the juice,it just gets the burnt flavor within minutes. Now I understand the joye510 batteries don't last long. But come on, my flavor cartridge tastes like crap! Anyone experienced with manual batteries have any input?
