Thanks Scott. Makes sense.

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.

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.
