I'm an embedded hardware engineer, so I don't have much experience with wire for high-current applications, but I was surprised to see soldering as the method for the connector. Can anyone working with high-power devices chime in on if this is more common than crimping at this gauge? Maybe solder is more accessible to the hobbyist at this wire thickness?
I build RC planes/quads, where 80A currents are not uncommon, and I use XT60 with 12AWG wire. I don't know if there's a crimped XT60 connector, but all the ones I've ever seen are soldered. I don't know why you'd crimp, it seems to me that soldering would be more efficient for high currents due to the larger surface area that makes contact, but I don't have specific data one way or another.
