Considering adding the 100W amplifier which will only be used in the field.
Not SOTA or hiking, car trips for POTA and, vacation use. I have a 20AH Bioenno
battery that more than adequately powers KX-3 at 10-15W for QRP activations.
I've considered 2 options: 1. Geta a higher capacity battery and run both radio
and amp from one battery (think the 20AH will do?
A 20Ah LiFePO4 battery will go a long while, especially if you power the
radio from it's internal battery pack, and especially if you don't CQ a
lot. One of the KX3's many strengths is that it is very miserly of
current draw on receive.
