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
Thanks Scott. Makes sense.

Hi Dennis,

batteries is not available, as far as I know. Even if it were, it would

So you're taking your 12v source (let's say it's 13.8v), adding an
inverter to make 120v, then plugging in a charger to bring it back down
to 13.8v.
I'm fairly new to the KX3 game, but it seems like I must be missing
something here.

One solution to charging the Li-Ion batteries from a 12 V DC source is
to use a small inverter. One I've found which works well is the Samlex
PST-120-12. It's a small "pure sine wave" inverter, rated 120 W, costing
about $120. It seems to work just fine with the KXBC2 charger, and
