Precaution<BR><BR>
<STYLE>
</STYLE>
<DIV><FONT face=Arial size=2>I recently had a well known LiPo charger develop
an internal short across the output. The charger finished charging a pack
fine, but when connecting the next pack a major arc removed a good deal of the
connector. The manufacturer confirmed that there was an internal component
failure and promptly replaced the unit (the thing was new and only used half a
dozen times.) This could have been really bad if the short had occurred
mid-charge with the batts fully connected.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I suspect that installing an inline fuse in
the leads between the charger and batts would be prudent. In-line fuse holders
are readily available (Radio Shack, auto parts suppliers, etc.) Probably
something in the 20A slo-blow range will work. </FONT></DIV>
