<DIV><FONT face=Arial size=2>No. As long as his battery is .2 volts above
the regulated voltage (5.7) he is okay. This means it would regulate down
to a battery voltage of 5.9. If the input falls below 5.9, say to 5.5 the
output will be about .2 volts less or 5.3. That is why the system
will not quit if you lost one cell in your two cell LiPoly
pack.</FONT></DIV>

<DIV>Bob,</DIV>
<DIV>You're right, the voltage out should stay constant.</DIV>
<DIV> </DIV>
<DIV>Jim,</DIV>
<DIV>The 480 is more than capable of maintaining 6.11 volts under a 1500 mah
load - and this is shown by Bob's test where the 480 holds 7.2 volts under
direct load. The 480 will actually maintain 6.11 volts with
substantially higher load (upwards of 5000 mah).</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
<DIV><BR>Dave Lockhart</DIV>
