Okay we'll in my true fashion I've been back a day and already had to order something new . I just put in my order for the OMG all day kit. I've only ever used the traditional battery styles, and some of the early tank models (not Vapor4Life big mistake) when they first hit the market. I was wondering if there is anything need to know about filling, and maintaining them, or big oops that can be avoided heh. I would hate to ruin something from sheer ignorance.
