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.
