Hi everyone! I'm new and have only been vaping since last August. Right now I have an automatic 78mm Volt from Smokeless Image with their mini clearos. I was wondering which battery in the Smokeless Image catalog I should choose for 1. longer battery life, 2. more vapor without changing the 50/50 formula of my e-juices and 3. not a drastic change in battery price. Also, what tanks or clearos are best and cheapest for said battery. Thank you everyone for the help. And I would really prefer to stay with smokeless image because I really like their product quality and prices so please keep suggestions for the battery to that brand.
