Hi Arno, If your fully charged batt reads 11.4 V AFTER the KX3 has switched back to 5 W, the voltage reading with 10 W (maybe 50% more current?) will most probably be below 11 V.
I would suggest that you try to gradually increase the output power from 5 Watts and read the voltage and currents from the KX3s meters. This way you will have a measure for the voltage drop and the series resistance in your battery connection and power leads.
