There is pretty much no standard at all. Some reputable retailers in north america will put anderson 45 amp connectors on motors and controllers etc, but the hall sensor plugs really vary widely. Some like mini xlr, some like molex, others use cheap blade connectors.
If there is such a thing as "most typical", it's the cheapie blade connectors common on scooters. On controllers, I'll keep the original blade connector plugs for throttles, halls, etc. But I cut off the cheap blade connectors on the phase wires and the battery wires and put on andersons.
