How to connect 50 A 12AWG cable to a shunt resistor in PCB?
I use something like the Keystone 8197-SEMS for best flexability. It and others like it are classified as screw terminals, but can be tricky to differentiate from a terminal block when searching.

Note, they are rather heavy if this is for a tiny plane. If I were building an ESC, I would use something like Anderson PowerPole PCB mount connectors which contain less metal instead if I did not want to solder wires directly.
