One hint with Deans...

Plug the male into the female before you solder.

The irons have a tendancy to melt the plastic as you work, so the other of the pair helps keep the pins in alignment.

The Deans are not recommended for higher amp draws... they are better used for under 50A.

BYW, these are very popular in the HAM radio community.  If you browse HAM stores or "boneyards" you can often find deals on them.

Yup, this ^ ∞!! I've switched ti APPs and haven't looked back. They're a big more expensive, but man are they so easy to use. And they use crimp connections, so no soldering!!

i use the 30 amp PP connections for everything so far, including my 8 cell 2000watt Slick and 74" Edge. You really only need the 75 amp if the wire gauge is too thick to use the smaller connectors. In fact my crimpers only work on the 15, 30, and 45amp connections.

I like the XT60's as well.

For larger setups I really like those red 4mm and bigger bananna type connectors they sell. They prevent you from hooking things up incorrectly but the actual hardware is not polarity specific.

That means you can make up all sorts of different connects and genders from the one type. There is no separate male or female. You can rig it up to be either.

It takes a try or two to get the plastic covers to "sit" properly but once done the connectors go together and come apart without problems.

You just have to remember to put the plastic cover on over the wires FIRST, then solder the connectors in place, You pull the red covers out towards the connectors to lock them in place.
No shrink wrap is used.

The larger units are good for fairly high voltage and amperage levels.

Inexpensive, easy to solder, easy to adapt.

Without a proper crimping tool, the connections can be lousy and end up generating heat and resistance. Solder nearly ALWAYS beats a crimp connection because EVERY strand in the wire is included in the connection. With a crimp, you can miss that.

Status: offline 		I use a 40 watt iron for Deans connectors with no problems. I flux and tin both the wire end and connector contact, then I touch them together and heat the connector. I add a bit of solder to fill in the joint when the tinning melts and wind up with a very strong connection. I look it over to make sure it has that frosted look and give the wires a good yank in every direction to make sure they are stuck properly. It definitely takes a little longer to get them hot with the small iron, but if you'll put the heat onto the connector instead of the wire there's not much worry about shrinking the tubing before you're ready.

Status: offline 		Tip: When you are doing this with the Dean's connectors, it helps to put on a spare Deans connector of the opposite gender, on the connector you are soldering.

e.g. If you are soldering a female connector, plug in a spare male connector NORMALLY to it.

This helps keep the back of the metal cool and not melt the plastic, and if the plastic is partially melted, it remains in place because of the mate.

-

That is one reason I prefer the snap in ( red plastic round covers ) bullet plug connectors HK and others sell, that seem to be coming standard with many LiPos now-a-days..

With these you can heat the bullet plugs as hot as you want to get good flow, without worrying about melting anything...

Actually, soldering rarely beats crimping in the connection. That's why full scale aircraft rarely use soldering on main wire connections. It's too susceptible to variations in soldering capabilities.

And if you choose to use APPs, then you just need to pony up for the 40 dollar crimping tool. It's cheaper than a good soldering iron, so I didn't have any problem with buying one.

Of course, i still have my trusty 60w hobbico iron for the rare times when i have to solder. This is mainly for bullet connections on the motor/esc now. But anything on the battery/esc/lipo charging side is now PowerPoles. It's the best thing since sliced bread. Also, if you get the 45A connectors, you don't have to worry about missed wires in the crimp.

I've been doing that whenever i solder Dean's. However, apparently Dean's has said not to do this because it can make a bad connection with the opposite sex side after you're done soldering.

Weird.

I'd imagine that if you get the metal too hot, the opposite connector could push the one you are working on away, making a looser connection... but by that point the plastic would be so soft that without the opposite connector in place, the metal block will just sag in place.

I think I'll go against Dean's advice on this one.

But I left deans long ago for XT60 for all batters 3s and below and the HK big red bullet plugs for 4s and above packs. Haven't looked back. I did have a lot of problems soldering the big bullets because my old iron was too weak but my 50watt one does a fine job.

yeah. i've been doing this ever since you recommended it without a problem. But apparently some folks have experienced a loose connection and loss of power while flying. Upon crash inspection, it turned out the deans connection between the male/female side was loose and you could jiggle it slightly to break the connection even when it was plugged together.

It doesn't matter to me any more since i've gone with APPs for batteries. But just telling you what I was told.

This is true. To use APP's, you really need to pony up for the 39.99 crimper to make the proper connection. Just like with Dean's or anything else that requires soldering, you have a one time expense to purchase the correct tools (soldering iron) necessary for the job. Since my hobbico 60w iron was only about 15 dollars, i didn't mind investing in the crimper. But in any case, you are correct that you MUST have the crimpers for a good connection with APPs..

Status: offline 		The reason Deans doesn't want you to plug in the opposite end is, now you've added another heatsink that is drawing heat away from the piece you're trying to solder, heating the plastic even more. I use the trusty old weller soldering gun with no problems. The secret is to heat up the tip of the gun till it starts to smoke, before soldering. I have no problems with 10 gauge wire with the gun. After tinning both the deans and the wire, let them cool, then put the wire on the Deans terminal and and put the heated tip on the wire till it bonds to the terminal. After soldering, the joint should look shiny. This is just my method and there are many choices, so try a number of them and use what you're comfortable with. I made this handy little clothspin holder as a third hand
