[ElecraftKX3] KX3 - what batteries to use

[Steve KC6ZKT]

The short answer is, the best you can afford. In my experience, the 
non-volatile memory will stay up at least 6 months without power being 
applied.

My choice for batteries in the my KX3 is the Panasonic Eneloop Pro NiMH 
[ https://www.panasonic.com/global/consumer/battery/eneloop/lineup.html ].

The KX3 is my favorite of my HF radios right now. In the long run, 
though, I wish that Elecraft would offer another option.

I always wind up carrying an external 6_Ah or 10_Ah LiFePo4 battery into 
the field when I use this radio, an external charge controller, and 
solar panel. It's not a big problem, but it also should not be a big 
project to improve this situation. The KXBC3 has enough real estate to 
include a lithium battery charger, and even a solar charge controller in 
its space. The amount of battery energy that could fit in-place of the 
NiMH cells could approximately triple the capacity of the AA cells.

So I have these questions:

1) How many of you out there might buy an upgrade which replaces the 
KXBC3 board with a lithium battery manager, and a associated battery pack?

2) Are there any 3rd parties already making anything like this?
