Precisely what I thought as well when I saw the picture. But wouldn't heat from the battery be a possible issue?
Good point. I am not sure how the heat would be dissipated. If the power draw was distributed equally throughout the band with no one cell, or group of cells taking the brunt maybe that would mitigate some of the heat. Again, I don't know. I am sure there are some smart people on this forum who can provide a more cogent answer to that question.
