Sure you can put the battery in "upside down". It's just the current flows one way or the other.Top to bottom or bottom to top.
It's all the same in the end.
As long as it doesn't complete the circuit to itself, there is no difference.
This is true, however if using a kick, the kick needs the body of the PV to be negative. Otherwise you are reversing the flow of electricity through the kick, and that, I imagine, would be a big no no...
Vaped her on the way to the restaurant for supper this evening and after getting seated at the restaurant I slipped her into my purse while we ate. When we left the restaurant I went to grab her out of my purse and realized she'd fallen over and every drop of juice in her tank was now in the bottom of my purse 8-o
It was bound to happen eventually BUT dang a bit of a mess to have to clean up upon arriving home. Note to self: Never ever put my mini in my purse again without being absolutely certain she can't fall over, especially when I've just filled the tank
