[Elecraft] KX3 Internal Battery - no Li-ion -- Why?

[Edward R. Breneiser]

Hello Elecraft,

I was looking at the KX3, but I see no Li-ion internal battery option -why?
I've been very active in portable operating and always use li-ion 
internal batteries even in my KX1. If properly installed, they are 
better than most other type batteries and last longer.  Why pick a 
battery technology that is stepping-stone battery technology?
