Urs,</FONT></SPAN></DIV>
<DIV><SPAN class=464542521-03022005><FONT face=Arial color=#0000ff size=2>The
Jaccio regulator is a great item, but I am concerned about running with more
than 3 volts of headroom: this increases the power
dissipation.</FONT></SPAN></DIV>
<DIV><SPAN class=464542521-03022005><FONT face=Arial color=#0000ff size=2>It may
simply require a heat sink be added to the regulator component. That is usually
just a tin or brass fin soldered to the big tab on the
IC.</FONT></SPAN></DIV>

Whadda you think?</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Hi Jim,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Many thanks. I have the Jaccio already. I
use it in conjunction with a 5 cell Nicad. Can I just connect it to a Li-Ion
battery or are there prior readjustments to be made? </FONT><FONT

<DIV><FONT face=Arial size=2>Hi Urs,</FONT></DIV>
<DIV><FONT face=Arial size=2>I like the 18650 cells that are in the 2000 to
2400 mAh range now. These are the cylindrical cells with metal cans
like Central Hobbies sells. I believe they are more rugged than the
Li-Poly cells and one doesn't need to worry about taking them out of the
plane to charge. I use the Jaccio Perfect Switch Harness but I'm
biased because I make them.</FONT></DIV>
