Great idea with the auto release!
I would use my new plug for the auto release. However, in a round shape.
With the new plug you don’t need a flat gasket because the gold plugs seal all around.

That is an awesome idea!

Here is my setup, I’m on a backpack
For me, this subject is the last I struggled with on my build when big wipeouts occur. I had to design several iterations before the good one, until when ???
I tried 3 options :
-1) Only elec cable with solid attach with a thin rope on leash plug and belt . Broke the cable several times because the shear forces on the rope attached to the cable is too high during a fall
-2) Elec cable with 2 x 15cm bungees on each end. One board side and one belt side. After the max elongation of the bungees, it’s like a solid rope and I sadly snapped a leash plug.
-3) Last idea was to combine a real leash because it’s designed for this purpose and the cable, heavier but more nimble. It’s a bit hard to take in account the max elongation of the leash to leave spare cable length on each side.
My leash is normally attached to the board + my belt, my cable is taken with the leash inside a sheath attached on the elec cable only with cable ties. It allows the extension of the leash inside the sheath.
And I added the first solution to secure the cable on both ends also.
When I fall, the leash first do it’s job and reduce the force on the cable if it tensions. And the cable is solid secured on both sides. It’s good for the moment
I’ll study the configuration with a waterproofed plug which disconnects when a fall happens. Interesting, thanks.

Nice works guys. I was thinking to move the battery off the boards too.
The connectors are awesome. Just a question, seen that my knowledge about electricity rise zero: but if after a fall the connectors unplug, there is any risk for electric shock at the battery ?
For a system in a backpack - a cable control solution fits perfectly.
It seems that controlling the ESC is as simple as an Arduino PWM signal…
Adding a pressure sensor would enable use between teeth, with a tongue, or with fingers.
I consider implementing it.
What are your thoughts?

I would like to test this cool new connector but could not find printables.
Could you give me a hint/link?
Thanks!

In the backpack ¿Cómo se hace para tener un buen enfriamiento de la unidad de velocidad variable?
It’s a classic heatsink like Foildrive

Why not run a coiled cable and leash through the centre? That way they have a similar stretch.
Or run a coiled power cable with a retractable leash through the centre.
If you used a disconnecting phase plug you may start popping ESC’s.
Hmm good point, can’t ever imagine falling and pulling cable connect powered up though…it’s always in the surf scenario when pod is out of the water and motor unpowered. Is quick disconnect and esc damage still an issue when esc is powered but there is no throttle?
This is exactly what I am doing this days, I felt guilty to leave my backpack foil assist taking the dust because I only use m’y tow since a year and I discovered Flow Custom V2 solution so I took the train 
can u throw up a link where u bought that coil cable.
I bought one but coukd only find 11guage and its pretty heavy
That’s 14AWG, isn’t it a bit light for our application? I guess the risk of wires overheating are mitigated in a marine environment, but there is definitely a power loss penalty over 2m of cable.
I went with 12AWG which is still a bit of a compromise, but weight and ease of use are determining factors.
ok, how about a link to the 12awg cable please
That’s the catch, harder to find in bigger core sections. You’d have to coil it yourself, possibly not as tightly as what Etienne referenced.
I’ve always used 3g2.5 in my foil assist systems with 12S since 2 years now. Like Foildrive V1 in fact !
This spiral cable thing is a mystery to me — why would anyone choose to hurt performance?
