New to vaping. Got my first Volt starter kit a few days ago. Absolutely love it. I'm using a 78mm auto-battery and carto's. I took the little rectangular felt holder that my extra battery was shipped in, sliced off the end, and stuck it on my kitchen wall. Makes a nice holder for the Volt, fits in there nice and snug. I keep whichever battery I'm vaping in there while the second battery charges. Is it ok to store it like this? I know it's ok for the battery, but wasn't sure about the carto. Thanks.
