I have the setup you describe. KPA100 and tuner in the separate enclosure and a K2 with the battery and the low power tuner. I power both with an Astron RS20 with the modification for charging a battery, RS20BB if you buy it that way.
I checked to see what would happen by turning off power to the power supply while transmitting. The K2 goes to low power but the low power tuner may need to be tuned. I also have a sailboat and during the winter I keep the 90ah deep cycle battery charged with the Astron. In fact when I first got the KPA100 setup I used the battery as power until I found the Astron on ebay. The boat battery will keep the rig up for several hours. I power my Laptop with the linear supply I used for the K2 before the KPA100. This eliminates switching noise. The rig and the computer have opposite polarity grounded so I need the separate supply. The computer battery will keep the laptop running for more than two hours on one battery.
