I have the KX-3. 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?) via the parallel power pole connection on the amp or 2. Just getting a separate battery for the amp. what are other folks' set ups? I seldom on the air for more than 4 hours as the family/ spouse looses patience. Thanks, Marc KM7AZ
