That Electric Lunchbox I Mentioned...

I plugged it into my 13 A-Hr Lithium battery and within a couple minutes the heating element was too hot to touch.  I put a Pyrex cup with two cups of water on it. Then I forgot all about it.  Several hours later, the water was warm.  The battery was so empty that even the LED voltage display was showing nothing.  It is recharging now.  I have no idea how hot the water got while I was writing a rebuttal.   I will try this again with a timer running.   Unlike the chemical heater that I used, the heating element was definitely too hot to touch for more than a second or two.
