So I need some ideas for keeping my tank from leaking at work. I work in a 34 degree cooler and every so often ill find juice all over my battery. My theory is the cold is making the o ring contract so the juice comes out where the coil screws in but also you can see the juice in the hole where it touches the battery. Ive been thinking about taking a napkin or cloth and wrapping the tank up in the case I use which I keep in my pocket so its not outright in the cold. My get up is an ego t 1100 battery with either a mini protank 3 or an evod 2. also my old tank that I gave to a friend was an aspire bdc. I use a 70/30 PG VG blend but am thinking about going back to 50/50.
