Hi Dave: You did terrific with the lower power.
Last year I purchased an Ampere Time 50 AH LiFePo4
for emergency power. They make them up to 400 AH.
Very happy with it, it has the built-in BMS and
stays above 13 VDC for most of the discharge cycle.
I'm planning on getting their 100 AH battery for an upgrade.
I paired it with a Bioenno Power BPC-1510A charger from HRO.
Very reasonably priced battery, runs my FT-991A up to 100W
for most of a day. I designed my own DC-DC UPS which
instantly switches my radios to it if AC power fails.
A classic KISS design with no voltage drop across it.
I probably should write it up for an article in Newsletter.
I put a large powerpole connector at the battery for connection
to the UPS, and a smaller one for the charger and other uses.
The battery is very light and easy to disconnect to take
with me for operating portable on 10 GHz etc.
