way would be sandwich thin pieces of aluminum between the cells and extend
past the edge of the pack. But I'm not sure I like the idea of placing
anything electrically conductive between the cells. Best to provide an air
space between the cells and duct the cooling air between them.</span></font></p>

style='font-size:12.0pt'>Of course, if you really want some wow-factor in the
setup, you would have a thermostatically controlled cowl flap that only opens
up once the pack starts to go beyond the optimum temperature. Maybe even an
emergency cooling system - a small CO2 cartridge from an air rifle might do.
