Ron,

Litium batteries are expensive and you cannot recharge them.  I'm in
the process of building a charging system for my weather station
which uses a lithium battery at night and on cloudy days.

I chose a 12V solar panel that charges a 12v lead acid battery which
in turn connnects to a device which steps the voltage down to 3.2
volts to power the WX stn when the wx station solar panel can't
produce enough to run the station.

I won't tell you which WX station I have but the name of it starts
with a D.  Three volt batteries last about a week or two in it which
causes me to have to buy a new battery for between nine and twelve
USD and climb up the tower to replace the battery.

The WX station I replaced with the one I now have had none of these
problems.  It charged a 6v lead acid battery directly with a solar
panel.  The entire system ran off of the 6v battery, which usually
lasted about two or three years.

Going green can be very expensive.  Keep the lead acid storage
battery.  You'll be glad you did.
