Hey first post guys, but been reading here for a while. After adequate research, my brother and I decided to start with 2 Vision spinners at 1300 mah, ibtanks 19mm xl size with smoktech prepunched 2 holed and juice from hoosierecig.com, mango and cherry vanilla at 60/40. while the mango is great the cherry vanilla was a pure fluke. And one battery works flawless. However, the other after initial charge ran out, cannot hold a charge! If say i charge for up to 5 hours! it never even stops doing the red/green flashin or the light turns off on the battery either like the other! it literally died after two vapes when i left it sitting off for your information as well overnight! while the tank and cartos seem okay, with 3.2 ohm 45 mm smoktech but they also seem to lack flavor and vapor production, the battery literally will not last for even 3 hours after 5 hour charge! I contacted hoosier ecig today and hope for a reply soon. I am chargin at 4.2 volts and doing everything correct I am beginning to get very upset I have owned for less than a week! Am i that unlucky small percent with a defective battery? Seems so. And any advice with new liquids as the mango was good but cherry vanilla was chemically and tasted like cleaner. The cartos seem to not be to awesome either? Any tips for better taste? Maybe get a 2 ohm? Yea but unless this situation is resolved I will not be buying anymore cartos or juice from hoosier cig, although I had plans to order more today! I really hope they take care of this issue because they were my planned site to get my smoktech cartos as they are a decent price and the juice is well priced as well, perhaps carto suggestions/ well priced sites and good juice sites/flavors? Am very new to a carto tank build and want to enjoy it like i enjoyed those disposable ecigs- lots of flavor and vape. And hoosierecig- should i even bother trying to resolve this or just go to a different vendor? I hope to stay with them. Thanks guys sorry for the long post, first one and hope we will be friends. lol!
