Do we need a revolution in connectors?
#16
There are plenty of connector types to find outside the RC world, and there you will see that connectors are much larger to withstand 100A or more. Within the RC world we see seveal manufacturers with their quality differences. Even with the simple 4mm banana plugs at an electronic parts shop you see different specs from 4A up to 60A and maybe even higher depending the build and yes or not gold plated.
120A or 150A is no continious current but only peak power, the drive time with the capacity can easilly calculated to an avarage current.

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..

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?

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.

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.
