I use my Kx3 with a external small LiFePo4 battery..
http://amd.co.at/anti/index2.php?Accus/small6Ah/
12.8 Volt , 6,6 Ah with BMS Inside...( No ext Balancer needed )
I charge it with some of my Foltable Solar Module..
62 or 74 Watt Triple Junction Solarmodule
For longer Outddor times i use my bigger LiFePo4 battery ( with BMS
inside, no balancer needet )
12.8 Volt / 17 Ah - I charge he a with some of my Solarmodules...

This batterie run very nice with my Kx3 / ft 817 / ic 7000 / ft 897

I went ahead and ordered the internal charger so that I have the clock and
so that I can keep a set of Eneloop XX batteries healthy inside the radio
for ultralight operations. I, too, am interested in solar charging of my
LiFePO4 packs.
If one feeds raw solar panel power to a battery, then things
Not exactly sure what balancing means but suspect this is the same
as equalizing charge. I have used solar charge controllers at remote
sites for two panels charging two batteries and do not recall any
equalizing function in them. The Buddipole appears to be a simple
current regulator. It
Hi Ed,
Terminology can be a tricky thing! So can the specifics of different
battery types and how to charge them. You raise a number of excellent
questions.
In order to assist other readers who may not be as familiar with the topic,
and to assure I am being clear, I will go in to some detail.
Wayne has stated that the KXBC3 internal charger will be for NiMh only and
will only be a timed charge, set to run an amount of time chosen by the
user, with a C/10 current rate of 200-250 mA. (He is considering a new
firmware mode to allow auto start of charging, though that is down the
priority
NiMH-only far as I know. There are safety issues with Li, and NiCd
types aren't often used any more.
If several charger settings are offered, it's a sure bet that some
user will set it wrong for the battery type being charged. This can
damage batteries and in turn cause them to bulge or leak.
John I have no knowledge of what Elecraft is going to do. In general there
are three distinct technologies out there and it is difficult to make a
charger that crosses those boundaries. Lead (car battery, gel cell etc.),
NiCd/Niah, and Lithium. With the higher efficiency and lower weight of the
Neither. It has been listed as a NiMH only charger.
