[MarinTeams] Lithium Batteries

[Bill Ruck]

Been reading the comments.

Lithium batteries have advantages but the major caveat and warning is to 
NEVER OVERCHARGE THEM.  If you try you'll have a fire.  One should not 
swap out lead acid batteries with lithium batteries; the charging 
systems are totally different.

If you don't believe me find a book titled "Bottled Lightning".  It is 
the story of the development of lithium batteries.  Each chapter ends 
with "and then the laboratory burned to the ground."

I've found a couple of lithium battery systems that integrate charge 
management.  One system is presently keeping a Contra Costa County 
public safety radio site on the air, but it's 48 V.

Just found a really good article about lithium batteries and could scan 
and share that if interested.
