<DIV>I've been thinking about this, and I think the best 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.</DIV>
<DIV> </DIV>
<DIV>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. ;-)<BR><BR>Bob R<BR><BR>--- On <B>Fri, 8/1/08, Jay Marshall
