I have a 12 Ah Li-Fe-Po battery that weighs only 4 lbs. It runs at about 13v.
In comparison, my 9 Ah Gel battery for my motor scooter weighs about twice as
much.
Yes. if you have to carry it up a trail, LiFePO4 batteries are
wonderful. I loaned by KX3 plus KXPA100 to AF6RT, who was hiking 2 miles
with 2,000 elevation change with W6JTI to light up a rare 6M grid. W6GJB
and I both loaned him 20A 13V LiFePO4 batteries. They didn't drain mine
in a day, and never touched Glen's.
Wayne Burdick, N6KR, one of the two owners of Elecraft and the chief
engineer, is a backpacker at heart. All of his designs squeeze current
draw to the absolute minimum, sometimes too much to suit guys using his
gear at home. :)
With the KX3, I recommend that users set the built-in RXEQ to roll off
everything below 400 Hz to maximize headroom in the earphones.
