Honestly with 50A of current we should be using connectors that screw into place firmly and have a single wipe or a single solid conductor pin style. Multi-pin connectors will always inherently have issues with imbalance of power delivery. With extremely slim engineering margins this is basically asking for disaster. I stand by what I've said elsewhere: If I was an insurance company I'd issue a notice that fires caused by this connector will not be covered by any issued policy as it does not satisfy reasonable engineering margins.

edit: replaced power with current... we're talking amps not watts

I was wondering if this was a thing - in RC quads and the like we use these massive bullet connectors (XT30/60/90 and similar) which often have lower resistances than the wires themselves.

Yeah, they take soldering for the wire/connector interface, but presumably there are connectors similarly designed with crimp terminals, or it's just something the mfgs will have to deal with.
