I've embraced
Anderson powerpole connectors for all my 12V power connections. I bought a bunch of the crimp connectors in various sizes, a bunch of red and black shells as well as a
TRIcrimp crimper so that I can make my own cables.
I put a
RIGrunner 4005H on my mount and feed it with a 10 gauge cable (large gauge to reduce voltage drop, not to handle high current) through the mount. I've replaced the connector on the dew heater controller with powerpole connectors. I've also created
2.1x5.5 DC coaxial to powerpole connector adapters for my camera and focuser.
