I have a love hate relationship with powerpoles.? I mostly hate them.? They are missing many features that make a good connector, but seem to be heavily used in this hobby because they are cheap and can handle high current.? There's no real keying features for multipin setups, the contact retention method is weak, there's no connector retention method, there's no strain relief for the wire in the crimp, no strain relief for wire going out of the housing... But I do use them just like everyone else, ha! (For the same reasons, cheap and high current capability).? I haven't seen any other low cost connectors that has all those features, so we're stuck with either XT65s or powerpoles. At least XT65s are keyed. Okay, done with rant.??

What I was drawing up wouldn't rely on the connectors for reverse polarity protection.? It uses a p-type mosfet with a zener diode.? On reverse polarity, Vgs is high, shutting the mosfet which means no current flow through the mosfet.? There is also an overvolt protection circuit, and an esd protection diode.? Overvolt protection requires a fuse to prevent damage to the power supply, but it does mean that if you accidentally plug in your radio to a 24v source, you're going to pop the fuse.? I want to go over my design a couple more times and I'll probably post it on the discord for community review.? It will take some time to get boards made and tested, maybe 1 month or more.
