<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Some have noted specific "No No's" with regard to charging
lipos - there are a number of universally agreed "Rules" that would
have prevented this situation (if followed), and there are a number of
theories/approaches/practices for safe charging, care, and handling of lipos
that also would have prevented this situation (if followed). And in
particular, there are rules/practices specific to the 109
charger. All of these things are discussed in detail in many forums on
RCU and RCGroups. From everything I've read, it is extremely rare to
see a lipo flame when good practices are being followed - but - the potential
always exists, no matter how small (keeping in mind potential
hazards/situations are everywhere in our daily lives).<o:p></o:p></span></font></p>
