How to install new connectors on to a battery?

[Will16 45]

Hi all,

I've just got a new brushless motor and ESC. My problem is that the ESC has a Deans connector on and my battery has a Tamiya connector on. I have brought a set of Deans and would like to know how would I go about replacing the connectors. I'm sure most of you would have done it?

Thanks,

Will

A pair of pliers or clamp (or tape a pair of pliers to an old plate or work bench)

Solder (good solder usually with lead but you can do it with lead free)

Hot Solder Iron (cheap ones from Maplins for about £15 will do)

Cut the tamiya plug off and strip bear the wire coating about 5 to 10mm and twist the end so its neat

Tip the iron with a bit of solder and heat the bare wire with the Iron tip (hold wire with pliers or clamp as the wire will get hot)

Touch the solder on to the wire while still applying heat with the iron, but dont melt the solder on the iron the heat within the wire should melt into it. This is called tinning.

Once you see a blob of solder soak into the twisted fiber of the wires remove heat and solder and allow to cool, dont blow at it or breath in the smoke.

Do this for the other wire then on to attaching to the deans!

You kind of do the same to the deans, heat the deans tab up and then melt solder on to it using the heat within the tab not the iron. you can touch the iron on one side and hold the solder on the other until it melts or same side is fine. Then while the deans tab is still hot heat the tinned wire end up with the iron tip and at the same time touch the wire and iron to the connector. All should blob together, remove iron and hold wire to tab for a few moment until the solder cools and goes hard. if you have octopus hands you can add a little extra solder when at this stage to create a neat blob.

Done!

I make it sound easy and practice makes perfect, just carfull not burn your self and dont stress if you get it wrong, trim the wire and start again with a new deans.

I just did a quick search and found this which is pritty much what i just wrote

NOTE!

Before you solder the wire on to the deans slip over a bit of shrink tubing over the wire and push it down to the end out the way of heat, once all soldered, slip up the shrink tubing and heat to shrink with a hot hair dryer or just hover the iron close to it and the radiating heat will do it but dont touch it to the iron it will just melt it, or a match/lighter flame

I'll add one very important thing: only cut ONE wire at a time when you're cutting off the old plug! If you try to cut both wires at once, you'll short out the battery with the cutters.

Better yet, cut one wire and leave the other one attached to the old plug, strip and attach the cut wire to the new plug, and only then do you cut off the other wire and strip and attach it. That way there's no chance at all of a short.

Thanks sooooooo much!!!! Havent had time to do it today but will have a go tomorrow.

if you are buying a soldering iron, go for something with atleast 40-50 watts, the smaller irons are a pain to use.

Yeah,

I have a gas powered small tip soldering iron for delicate electronics work (single strands etc).

But for soldering big heavy wires to brusless motors and Deans plugs I had to go out and get a bigger one. I went all the way to 80 watts, but I believe 50 should do it.

Well it went really well and the battery has held up great in the Lake District this past week. I also used the spare corrosponding connector to make s battery charger lead, usin the same technique.
