Hello all, I'm back to vaping after trying it 2 year ago with green smoke but got feed up with the small batteries....so this time around after a lot of research on the forums here I had decided that a tank would work best for me, so I purchased an envy ego t a few months back and 3 months with it and still have no problems at all and still on the original atomizer. Since I have using the atomizer for 3 months I'm expecting it to fail soon, so I wanted to know if it is possible to just keep the batteries and just put on an joye ego c upgrade instead? Something like this http://www.myfreedomsmokes.com/parts-accessories/ego-compatible-parts/ego-atomizers-and-cartridges/joyetech-ego-ego-t-to-ego-c-upgrade-kit/ on my envy ego batteries. Another thing is that envy has a 1 year warranty on both the batteries and the atomizer which I find strange having a 1 year warranty on the atomizer. This is the hardware that I currently have https://www.envycig.com/index.cfm/id/3/ca/detail/ProdID/73/category/0/ thanks for all help
