It really depends on your mode of operation. The internal batteries do a great short term op. 5 to 10 AHR batteries go longer, Same with solar panels will let you do daytime and most of the night. Of course depending on the operating mode.
I use a 10 AHR Life type with a 27 W folded solar panel and have never ran out of SSB power. Have fun.

Subject: [Elecraft] KX3 Suggested External Battery
I'm sure this question has been asked many times. I recently bought a KX3 so
I'm new at QRP and I'm about to head to a camp ground in a few weeks and go
portable. Besides using internal batteries, what longer lasting external
batteries are recommended? I hear of Lipo batteries and a slew of others.
I'm just trying to navigate though the maze of options.
