Thank you to everyone who has given me advice on this issue.? I have
gotten great lessons in battery chemistry and management.? I also
realize too that I had greater expectations on my battery than it
could deliver.? I am planning an upgrade of my photovoltaic system
including batteries with greater capacity. So I expect that will get
my TX up to 100w.? I don't plan on running an afterburner, aka
amplifier, figuring I can compensate for more power (sorry, Tim
Taylor) with my location (high, surrounded by salt water) and? good
antennas.?
I am one of two radio amateurs on the island.? The one has a "super
station" but is 100% dependent on the grid.? I prefer to work
portable and off grid.? One never knows if and for how long the
electricity will be cut off here.? No APRS activity here, but I do
have some good (PAT) Winlink connections up in Switzerand and
Germany so I can get information out and receive it.? Not many
people here are impressed with the communications possibilities of
amateur radio.? Too into internet and 3g/4g/5g cellphone service, I
guess.
Vy 73 to all Ops!

I also agree with Ed, especially regarding the C rating of your
LiFEPO4 batteries. I built a solar generator based on Julian¡¯s
(OH8STN) 576W design and when researching this chemistry I found
there was a wide range of C values, which tells the amperage that
the cells can put out. It would be interesting to see what your
cells¡¯ C rating is.
BTW, operating in an olive grove surrounded by salt water sounds
like a very pleasant operating environment!
