I bought a eGo kit that came with 2 joyetech batteries, but the charger was a knockoff. A week later the charger broke so I bought an actual Joyetech model. Now it seems that my batteries are dying way quicker. I should add that around the time I started using the new charger I modded my tanks with SS mesh wicks. I can't imagine it's the new charger so that leaves the new coils as the culprit. Any thoughts?
