Poked around a bit (such as this thread) for info, but didn't quite turn up an answer.

For smaller gauge wires (anything under 14 or so), you can find plenty of crimp connections all over. JST, as an example for really small stuff and the ever present, and very generic, bullet for larger:

Skipping over the mid range, in the BIG HONKER leagues (6AWG or thicker) you get into hydraulic crimps but have landed into lug mounts instead.

I can't find bullets that crimp for the 12/10/8 range.

I've typically resorted to XT150's as my weapon of choice in these situations, but it does require a good chunk of time and solder to get that to work -- especially getting the thick wires heated up enough for good penetration of the solder. There are anderson connectors rated for 120A, but they are comically large...like, my god those are hilarious.

SO:

Where's the missing link of big, crimped bullet connectors? Do they just stop existing around 14AWG and everything from there is solder bullets or crimp lugs?
 
Interesting design -- dunno how much I'd trust those to not move around and disconnect without having to apply an external (tape, shrink, etc) fastening.

Inline set screw terminals -- I can see some potential there. Probably not as reliable a transfer of power as a full crimp, but perhaps with a good set of ferrules, might be reasonable.

There are also connectors like this.
That's a permanent connection, which since I'm looking for bullet connectors, it's implied I'd like to disconnect without cutting :)

Those are what I use for phase wires on my bikes. I use Anderson SB50 connectors (with the same crimp terminals) for the battery wire. Yes they're big, but they're also reliable, secure and long-lived. They don't need any solder but can easily be soldered to accommodate undersized wire or lack of a suitable crimper. In a pinch I once soldered some with a heat gun. Try that with an XT connector!

50A 3ph wall plugs are big and bulky too. It suits what they do.
