Hello Guys,
What is everyone using for their removable link on their heavyweights?
I've had a look at some off the shelf connectors and they don't seem to be rated for the types of current we are pulling (400A max burst @ 28.8V)

In Kan Opener we used 3D printed tripple EC5 connector.
But if we would do something simular now, it would be EC8 in a 3D printed housing.
Those EC8 are rated at about 350A, so should be fine. We are going to be using two of them for Triforce.
Does your 3d printed housing have a way to stop the connector flying out on heavy impacts?Quote:

Nice, thanks guys. 2 EC8's it is!
Hi,
I'm using 2 EC8's too. Has anyone designed a printed mount for these?
S
I'm sure I'll be printing a mount for them in the near future
The replacement for the big Andersons.
I love the click and the positive hold they have but they are huge when compared to the EC8s or similar.
Quad EC5 with a cover held over the top by 2 wing nuts, also using a 3D printed case.
*four* links?
One per motor: for safety, trouble shooting and making sure we don't burn any connectors out.Quote:

Since we went to EC5 for Bullfrog, we didn't suffer from that anymore.
I have used a 2 pin plug and socket, on the socket my positive is wired into - and out from
+ and I have joined the pins in the plug. The plug has no fuse and therefore no rating, will this be allowed?
Do you mean a mains power plug? They are not rated for the high currents in a heavyweight and it will likely melt.
EC8's are fine.. but how you mount them is more important. If you just have an access hole with no cover/ no physical stop to prevent the connector coming out... it probably will.
What's the 'done' way to keep an access cover closed?

Yeh, it's an older ceramic 2 pin wit the copper pins Joined by 16 AWG cable - is this a no go?
2 copper pins joined by 16 AWG inside ceramic seems more robust and heatproof than an XT60 or EC5 or 8. The build rules just say ratings need to be adhered to but this has no rating on it, is it a case of testing it and if it doesn't melt I can use it? :)
Is it just a household plug going into a household socket, like this?

If so, it will work perfectly fine in terms of making and breaking the circuit, but it will pop out far more easily than a Deans, XT-60, EC5/8 or Anderson connector. We used ours in a featherweight (non-combat) and just getting bumped from other feathers was enough to dislodge it.
Have come up with this, rather than using the standard bolt-in fuse holder I made a fuse clip which I will mount in a recess, basically it's a giant version of a blade fuse used in cars so now the fuse doubles as a kill switch.

Never fails to amaze me how roboteers can take something so simple and make it complex as hell. For reference the LED thread is a good 1000 posts or so long when those first came in the rule book.
The led thread was initially not about power led though, but on failsafe led as it was written into the ruleset.
Fair point but it's half the fun. Ended up with this in the recess:
