[Elecraft] Being cautious around Li-Ion Batteries

[David Gilbert]

That's the part lots of people here don't seem to understand.  There is 
inherent jeopardy in having lots of stored energy in a small volume, 
coupled with a low enough internal resistance that allows very high 
current to flow in either direction ... both of which are the case for 
Li-ion batteries.  All reputable Li-ion batteries have control circuitry 
that limits charge/discharge levels to reasonable levels.  If that 
circuitry goes bad, or doesn't exist in the first place, bad things can 
happen.  It's the nature of the beast, and isn't limited to Li-ion 
batteries.  Put enough energy into a small enough space and we have the 
potential equivalent of a bomb, period.
