<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><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>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 <I><lightfoot@sc.rr.com></I></B> wrote:<BR></DIV>
