There's not a whole lot of info out there, as well as not many making DC
- DC chargers that will work on LiPo or LiFePO4's.
I went down this road a couple months back looking for something to run
my KX2 mobile out in the boonies and still be
able to charge without use of a geny. I stumbled upon an outfit out of
VKland that seems to fit the bill.
Company called REDARC:
https://www.redarc.com.au/battery-chargers/in-vehicle-chargers They
do have a US distributor now
from what I can tell. Their unit also has Solar input - which would be
a plus - and designed to handle the new
"smart alternators" that are common on newer vehicles...I didn't know a
thing about these newer alternators until
I found this site. This is a common deal in VK with all the
"overlanders". Dual batteries to run the fridge, radios, and
other camp assy's while in the "outback". Charge off of solar while
parked, 12vdc while in motion, to keep the LiFePO4's
(aux battery) charged.
I've used a goal zero inverter, and it works ok - if I don't use it and
any radio gear at the same time. ;-)

Hi Dennis,
You're missing the charge controller. Li-Ion batteries are very fussy
about the way they are charged. While it would be more efficient to
run the charger directly on 12 Volts, such a charger for the Elecraft
batteries is not available, as far as I know. Even if it were, it
would probably cost more than the inverter. The inverter, of course,
also has other uses.
Elecraft also makes it very clear that their batteries shouldn't be
charged with any other charger, and there are good reasons for that.
