Re: [Elecraft] KX3 firmware request - separate internal/external power supply settings
If it doesn’t (or can’t) show up in firmware, there are external solutions that can accomplish this — for example the Buddipole PowerMini. I keep one in-line, even without a solar panel connected for just this purpose. It will both alarm and disconnect the external battery when it reaches a preset low voltage. > > Right now there is just the "Bat Min" setting that gives an alarm if the > present voltage drops to a set value in the configuration menu.

[Elecraft] KX3 firmware request - separate internal/external power supply settings
Right now there is just the "Bat Min" setting that gives an alarm if the present voltage drops to a set value in the configuration menu. (Automatic shutdown happens at 7.0V according to the manual.) I use an external LiFePO4, and internal NiMH. These have different specs. I would like to see more configuration options that allow me to "disconnect" the external LiFePO4 when it reaches a certain voltage (10V) and then switch to the internal NiMH which may be (and likely are, at least in short order) at a lower voltage than the external. I would also like to be able to have the ability to make the auto-shutdown happen at a higher voltage than 7.0V (8.0V in this case.) Under the current setup, power is supplied by the higher voltage supply, which can result in a ruined external battery (if the internal protection circuitry of the battery should fail) as the power supply would flip-flop between the two. I would like to have a little bit more control. Maybe that's just a personality defect.
