120A or 150A is no continious current but only peak power, the drive time with the capacity can easilly calculated to an avarage current.
Well its its sort of continuous and sort of not. Its longer than a "burst pull" but doesn't run continuously. Its acceleration amperage, a few seconds until you are to speed. Im fairly certain thats what they rate the connectors and wiring on.

Never gonna happen. People like certain connectors. Lots of people like soldering, and making things the way they want. The old way, before all the RTR stuff took over.

This hobby has been around for decades and the servo companies still cant agree on a standard spline count..

True, Ive been in the hobby myself for 15 years. I guess its just hopeful thinking. I mean for the most part standard size servos at least have a standard of 25T.

Not sure if someone will find it useful / interesting, but AMASS makes a tonne of different connectors in 2-pin and 3-pin, and the range is growing on what seems to be a monthly basis.
It's worth exploring ebay / alix to see the range of options.

There are 3-pin varieties called the MR30, MR60, MT30, MT60 (flat and triangular respectively), there are XT90 (and others) with spark-limiting resistors built in, there are variants of connectors with balance terminals built into the main connector (which I predict will eventually be the future, since balance leads are a messy weakness of modern batteries in higher cell counts).

Most interesting to me there are more connectors being released with screw-mountings on the female side. I've been using the MR30s to provide a detachable link between ESC and RX (in 1/8 scale) so I can easily remove the entire ESC/battery tray together for cleaning. They're more reliable than JST and provide a more solid connection.

You can wait/hope for them to become real standards, or just pick the best connectors and standardize across your own fleet. Why wait?

Interesting... I have some Amass Anti-Spark AS150 connectors myself. If the EC5s supplied with my new LiPos are not strong enough for the system (because its VERY unlikely I will ever completely max out the 150A of the TP Power 4050 motor on a 1/8 ~12lb vehicle) then my AS150 connectors will be my solution.

I more of want a standard because it can be very scary or even dangerous for some people to change connectors on the LiPo side. I have no real issue doing it but I generally try not to mess with LiPos myself. Then theres the issue with wiring. Some packs that are massive and will be used in 8S+ vehicles come with 12AWG wire. And it is NEVER a good idea to attempt to change the wiring on a direct-wired pack, by absolutely ANYONE. Yea sure, the 10AWG coming on my new packs is sufficient for my use, but only just. Literally any higher amperage draw and the wiring would be at serious risk of overheating and melting.

So its literally these couple, simple issues that warrant this discussion.

Probably the same reason we don't have only one car/tv/phone/tire manufacturer etc.. People want variety.

have you got a link on these screw connectors? Ive been using this style on motors for years but my favorite has been discontinued and I need a replacement.

Ya Amass makes a TON of different connectors. The chinese language site seems to show more than the english one:

Just bought a ton of the mr60 to make switching to the hand out motor at the track easier. Its from china though so it will be a while before they get here. The track i go to just solders 3.5 bullets directly to the motor and the connector is perfectly spaced for it to slide right on.

Bought 50 of them but only need 2 lol. Figure i could sell the rest to recoup costs cause it made way more sense to bulk buy. Like 1$ per vs 7...
