If I forget to turn down my screen brightness, I can always swap out batteries midstream. Again, thank you very much for the thoughtful insight. The debate continues...

Pretty cool to multi-purpose the high-end lithiums. Ever try any of the blue bricks off ebay? Must be using a different battery than the one in the photo or keeping the brightness super low. 10A @ 2A/hr = 5hr battery life.
