Best way to repair EC5 connector

[FrankyArseneau]

One wire snapped, can i reuse metal connectors and juste redo the 2 wires if i cut them even length?

You'll need to remove the remaining wire from the solder cup on the connector with a powerful soldering iron. The factory solder is lead free and takes a lot of heat to remove. Ideally you'd plug the connector into a male EC5 or IC5 that isn't connected to an ESC to act as a heatsink and make sure the bullet stays in place. It would be significantly easier to cut the other side, strip some wire sheath off, and solder on a new IC5.

Mmm ok, sounds more complicated than i believed haha.
I do bot have a powerful soldering iron. I will look into it.

Don't try and fix that, it's more trouble than it's worth. Easier to replace it.
Any local hobby shop?
If not, soldering ec5 isn't too hard. I'd plan on screwing one or 2 up before you get it right though.

Agree.

It'll be easier to cut off that connector and resolder up a new one.

Pardon my ignorance but you mean buying a new connector with the 2 leads? I would just have to solder them ?

Don't need new leads, but would need new connectors. Salvaging a used ec5 is tricky and hard. Once they are apart, they don't go back the same way.
Need 1 new housing and 2 new bullets.

Awesome thanks everyone!!

I am tempted to just buy this, cut it and solder..then heat shrink it all clean.

Thays ec3, too small. Need ec5, but otherwise idea works.

Sorry did not noticed it was EC3 lol. But yeah, same logic.

Whatever you think you should do…. Don’t, and just do what cancelthefuture said.

IC5 is a bit expensive compared to EC5 but it's easier to deal with. Unless you use telemetry I prefer SC5 from SMC, cheaper than IC5 and easy to solder. IC5 is more commonly available though at hobby shops. When I first started soldering I thought soldering two wires together twisting the strands was the easy way to go but I was very wrong. Soldering bare wire into a connector solder cup is so easy a caveman could do it. Add a little solder to the cup with your iron, add a little flux to your wire, add a little solder to the wire, smoosh it onto the cup and add more solder. Ezpz

I used to by a new connector with wires attached on amazon and splice it onto the old ESC or battery wires. That works, but usually the connectors are crap and I've had a lot of crappy EC5's melt themselves together. Eventually I bought a "nice" soldering station of Amazon for $50, and stocked up on Progressive RC EZ Solder EC5 connectors. Now I just pro-actively replace all of my connectors right away with Progressive RC EC5's, on all batteries and and ESC's. No more adapters, melted connectors, connectors that are difficult to disconnect. My favorite thing about the Progressive RC EC5 connectors is how it is always so easy to disconnect the battery from the ESC, unlike many cheaper EC5 connectors I've experienced.

Oh, my lucky day...found that in my stuff.
Its an extra i had for my batt charger. Il cut up that one to fix for now.

Dude, just don’t do it. Splicing wires is not the way to go here. You’ll have far more resistance in the connection and you’ll just end up building way too much heat and start melting things.
I’m reading between the lines here, but I’m guessing you’re just going to try and twist the wire together and tape them or something. Or crimp them, because you don’t want to solder? If you can’t solder, take it to your LHS and let them properly solder on a new EC5/IC5. Or maybe a friend can do it for you.
Not trying to be sand in the Vaseline here, but soldering on a new connector is not only the easiest thing to do, but also the best thing.

Yeah, i have a friend thats retired from working in electronics..annd sort of equipment. I think i will go pay him a visit .

 

[FrankyArseneau]

But, i was in fact thinking of cutting the wires, solder them (not twist) and then heat shrink.

Some people make their own luck, others their own misery.
