I have used similar configuration (except for the antenna) with 25 A/h
LiFEPO4 battery and could run at 100W at least 4 hours non stop plus another
hour with 60-70 watt output when battery voltage dropped down somewhat. Two
of these batteries and 120W solar panel allowed 24 hours portable operation.

I have done a fair amount of portable operation with a KX3, KXPA100 and
CrankIR vertical using a 12 v deep cycle battery .... and have ALWAYS had
issues when I try to run 100 watts even when the battery is fully charged
.... the battery just doesn't have enough ..... so I back the power down
to
50-60 watts and it does just fine .... personally, I'm happy to have the
60
watts so have not considered it to be a problem.

Subject: [Elecraft] KXPA100 on battery.
I just purchased and put together a KXPA100 Amp. I want to use it at home
with my power supply (same one Elecraft currently sells). But I also want
to
use the amp with my KX3 out of doors in a portable situation.
I tried my KXPA100 with my 12v 22ah battery and I received a "LO SPPLY"
message on my KX3 along with the bottom right reading "PA FLT". Go in
touch
with Elecraft and my battery is not up to the task of giving my
KXPA100 12-15amps. I will recharge my battery and try again.
Question: Will a voltage regulator like the N8XJK Super Boost regulator
work
and or work well with my KXPA100? Does anyone use their KXPA100 portable
with a battery?
