I just got a new KX3 with an internal charger and I am wondering what brand
and type of batteries you've had good luck with. I'm guessing the memory
requires an internal battery of some kind?

I?ve had my KX3 for several years and have the internal battery option but have always used it with an external battery. Just can?t take a chance of a battery leaking or something inside the radio.

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?
