On most RC vehicles, they'd use individual "bullet" connectors for this, which are like high-force banana plugs. The idea of single-conductor connectors is nice because if your ESC has the wrong idea about which way is clockwise, you can just swap any two wires and fix it. That only happens once during setup though, so I don't treat it as a major virtue.
On the downside, they're pretty primitive as connectors go, it's hard to find reputable/genuine product whose materials and platings you can trust, and you're on your own for waterproofing, which typically means glue-lined heatshrink. And if you plan to disconnect them (why else would you be putting a connector there), cutting off and replacing the glue-shrink every time gets old in a hurry.
Sadly I don't know a lot of better options at the kind of currents you're probably running. There's a Metri-Pack 630 line which might work, but I'm not wild about Metri-Pack in general, they also seem to lack the sophistication of more modern designs, and ordering all the individual piece-parts gets tiresome. There are a ton of interesting connectors for less power, or for high power but unsealed, or for high power and sealed but freakishly expensive (mil-spec), pick your poison.
