We’ve got three instances of destroyed radios in our local group alone. Connectors are nice, but that doesn’t stop people from putting clips on storage batteries backwards. ??
It can be done with series diodes in low power devices ;
P channel mosfets in medium power ;
And in diode controlled relays in really high-powered devices?
Dc-powered radios that ?I consider valuable to me , I generally provide protection for!
Our local group just did an Arduino based Winkeyer ?project, and putting a series diode in there before the voltage regulator was easy ; most of my HF go boxes have mosfet ?protection?

Yes, I see how that will work. But for a QRP rig such as sBitx one certainly doesn’t really need such a big bundle of connectors to carry the load. I understand that it is simply for making the polarity foolproof.?
