I charge my RC lipos on the stove (HAHA I cook them for good! Really, the stove is heat proof, somewhat ventilated, and can be taken apart hot.) I have lipos in my phone that gets charged on my nightstand. My laptop has lipos. The technology is everywhere.
I can say there is a need for "screw shields" in a number of designs. How about a cut up plastic bowls or aluminum flashing with some double sticky to the back of where the screw comes through. Running a screw into a battery is no harder than running a screw into something else it ought not hit...
