[Elecraft] KX3 Suggested External Battery

[Kevin - K4VD]

​I'm going to second the Bioenno solution. I use the BLF-1215W and it kept
my KX3 running through Field Day last year along with some other shorter
term field events. I often run the KX3 at 3 watts when portable with
intermittent forays into 5+ watts when deemed necessary.

I have not had any issues with RFI from their charger but, and I believe
this is common, what is quiet for some is noisy for others. Maybe the RFI
issues Jim reported has already been addressed? One thing I've been warned
about... LiFePO4 batteries have special charging requirements. Not any ole
charger will do.
