<HTML><FONT FACE=arial,helvetica><HTML><FONT SIZE=2 PTSIZE=10 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> I have tried to stay out of most of this discussion but something is gnawing at me. I have asked this question before, but don't believe I have gotten an answer. Maybe no one on the list knows <BR>
<BR>
Since Li-ion and Li-poly technology is widely used in cameras and cell phones, and these are recharged all the time (in the home and without special power supplies like separate 12 volt sources and such) with extremely safe circuitry, why is it that the folks who offer these same battery types to us, use charging circuitry that isn't so bullet proof???<BR>
<BR>
Certainly currents and voltages are different in some applications, but the chemistry is the same. And Lithium metal will burn with ferocious intensity whether 20 grams are exposed or 10 times that amount. The heat is enough to burn your plane or house either way.<BR>

First off, I'm not looking for compassion. That was a simple explanation as<BR>
to why a guy who is normally cheery, laughing and all smiles could go into a<BR>
practically homicidal rage over a smart a* comment<BR>
<BR>
Secondly and most importantly, I'd like you to explain to me, with as much<BR>
detail as you'd like, how my position is extreme in any way, shape or form.<BR>
To me, an extreme position would be "ban lithium batteries". I have never<BR>
said or proposed any such thing. I'd like to know how recommending caution<BR>
and informing the uninformed could POSSIBLY be viewed as extreme. Or is<BR>
anyone even bothering to read, or are they just glancing and knee jerking?<BR>
<BR>
And I don't need any type of apology, but thanks for the thought. I mean it.<BR>
