Early,<BR>
That's good advice!<BR>
Do you think the balance tap needs protected as well?<BR>
I learned my lesson when I had my LiPo fire that I wrote up in my column not too long ago.<BR>
But for the grace of God...<BR>
Thanks!<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>
