No offense is taken.  No argument is intended.  Just a clarification.

My motivation was simply to point out that there is a significant risk tha=
t needs to be researched and mitigated by anyone who wants to make their=
 own battery pack from new lithium battery cells.  I thought the original=
 poster of the idea might be unaware of this particular risk.  I think I=
 qualified my statement by saying that modern lithium batteries were outsi=
de of my area of expertise, and that while the risk/benefit of building my=
 own battery was not favorable for me, it might be for him.  That's all.=
  I suppose I came across as a wet blanket, but the downside risk is consi=
derable in this particular case.  He may be a professional battery enginee=
r (or have a friend who is), knows that it will take a huge amount of effo=
rt to get it right, but be willing to do it anyway.  (Then he can sell his=
 idea to a battery manufacturer and we'll all be buying his product, eh?=
  Capitalism at it's best!)

I'm doing some things on my Lancair that may make another person squeamish=
.  We all are.  But they are different things for each of us, partly based=
 on our own level of comfort but also based on our own experience and know=
ledge.  That's the beauty of the experimental movement.  We can do what we=
 each think is safe.  But I welcome anyone who says "this idea of yours ma=
y be dangerous, please check it out and make sure it's safe".  That's all=
 I was trying to do.

I was also trying to express a legal disclaimer like Brent Regan's "I am=
 an idiot, I know nothing", which in Brent's case most of us don't believe=
 anyway.
