[Elecraft] Fire in the house li-ion

[Bill Tippett]

Ditto Terry's comments.  I'd add that balanced chargers (<$20) and
inexpensive monitors (<$3) will detect when a cell begins going bad.  One
cell having a much lower voltage than the others is an immediate flag.

I also never put any lithium battery (LiPO or Li-Ion) inside my radios.
I've seen more bad publicity about Li-Ion batteries (e.g. Samsung S7
phones, Dell laptops, etc) than LiPO batteries but I'm not sure why that is.
