Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

2 Soldering

Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

    I'm not entirely sure if these are able to be ordered, but is there any chance you could carry XT60 connectors? They work so well, and are so easy to solder. Please excuse me if this isn't the correct place to post this. Feel free to move it (or erase it) if that is the case.

    Warning! These are NOT Deans brand connectors! They are counterfeit/knockoffs. I ordered a bunch of these and they are clearly not the same as the real Deans connectors I have. The blades are rougher, the gold color is much lighter (usually indicates less gold in the mix) and the springs aren't aligned properly. The force of the springs is weaker. Pulling these apart is a lot easier than the real Deans which can mean a weaker electrical connection.

    I am quite surprised and disappointed that Sparkfun, a company I have always thought supplied quality products, would do this.

    Other companies sell these counterfeit/knockoffs too but the are called "T" connectors or "Deans compatible" so you know you are not buying the real thing.

    These are great little connectors. I used them to replace the wimpy connectors on some of my larger LiPoly batteries. They don't come apart easily (they can actually be really hard to separate) and they carry huge amounts of current. Who could ask for more?

    A few tips with these: 1) Use flux (as in, actual flux, not just rosin core solder). The soldering contacts on deans connectors are exposed to air for extended periods of time and have oxidized making them a little difficult to solder to. 2) Use an adjustable temp soldering iron on medium high heat. You've got to heat up a relatively good sized chunk of metal in order to get good solder connection. 3) If you have it, use silver solder. It isn't absolutely necessary, but it will make soldering to these a little bit easier, you'll have a more reliable connection, and you will have less resistance in your solder joint (which is important for high current applications). 4) Cut your heat shrink perfectly square on the ends. Otherwise, you are going to have exposed conductor that could short circuit accidentally later.

Not real Deans Connectors

I bought these thinking they were genuine Deans connectors, but they are actually cheap knock-offs. They are made out of a very cheap polymer and the plugs are not very precise. Several had a hard time meshing with each other or with my other real Deans connectors. Some came with crooked pins that I had to bend back in place. The contacts are also MUCH harder to solder to than a real Deans connector. I had to get the contact very hot for the solder to stick. So much, in fact, that it began to melt the cheap polymer! :/ I've never had these kinds of troubles with genuine Deans. Explains why such a low price! I won't be buying these again. Update: One of the plugs wouldn't even make a solid electrical contact, which is pretty pathetic.

I'm sorry to hear that you are not satisfied with your connectors. If you would like a return, please contact us --

Nice, compact connector

Anderson Powerpole connectors have been my go-to connector since the '90s, but I thought I try these because of their compact size and high current capacity.

I think these are excellent connectors for the price+performance and the ones I received all were perfectly interchangeable with each other. They have gold plated terminals with a huge mating surface which are held in place with a leaf spring. The only nit I have to pick is it lacks the heat shrink tubing one needs to complete assembly.

After soldering, I'm very pleased with the result. I didn't t have any of the problems of the other reviewers, but I'm pretty used to soldering connectors with "big" lugs. It's much easier to solder terminals and then insert them into the housing, but this design is inexpensive and very compact for 30A terminals.

The key to success soldering pins in a plastic housing is to hold the pin you are soldering with a 3rd hand tool or similar while you soldering, not the housing. If you hold the housing, you risk shifting the pin when the plastic gets soft as you push on the tab with the hot iron. Insert the male half when soldering the female side. Again, hold it by the metal pin on the male side. Shift the holder for each pin before soldering. I tin the tabs and wire ends with 60/40 solder at 375C before soldering them together.

Pain to solder

Would be easier to solder if they had a hole in them to put the wire through.

That's a great point. We don't make these, so we can't revise them. But I will mention this for future information when sourcing new parts. Thank you
