[Elecraft] [KX3} Charging internal batteries

[Arlen Fletcher]

Well, that’s one way to do it. On my KX3 I simply turn the VFO B knob until the display is showing PS voltage, or BT voltage, whichever I desire.

So, if your external supply is at a higher voltage than the internal batteries, that voltage is what you will read.  If you want to see the voltage of the internal batteries only, you will need to disconnect the external supply.
