<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I inadvertently left my switch on
after flying last weekend. The flight pack with a 2s lipo and regulator sat on
for 9 days and drained the lipo. When I checked the voltage on the 2s 850mah
lipo it read under 2.6 volts and dropping under load. Without the load it rose
to just above 3 volts. SO obviously I drained my 7.4v 2s pack quite dead/flat/
ka-put. </SPAN></FONT><FONT face=Wingdings size=2><SPAN

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I tried to recharge it and none of
the lipo chargers I have would even allow it to begin charging. Then thinking
I had nothing to loose at this point I put it on my nicad charger for a few
moments and got the voltage up some. ( Yes I know this normally is a NO-NO and
I did it very cautiously, outside.) <o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Then the Accucyle Elite accepted
it as a 2s pack and began charging. I eventually charged back over 900 mah
into this pack rated as 850mah.<o:p></o:p></SPAN></FONT></P>

yet but I will to see what capacity It can output &
recharge.<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">NOW , my question to the
collective wisdom is. Assuming the pack cycles within acceptable output
IE (800mah or more), Do you think the pack is useable or should I just trash
it. How much damage could have been done by slowly draining the pack
flat. I think it wouldn’t be as severe as draining a pack flat under load( in
flight).<o:p></o:p></SPAN></FONT></P>

comfortable flying my pattern plane with it, but would it be usable for sport
flying.<o:p></o:p></SPAN></FONT></P>
