Lipo connections

[fly boy3]

Hi all, I don’t know if this is correct but I was told or read that someone supplies Lipos with main connection of your preference. Don’t like soldering this very important connection. Any info gratefully received.  Thanks

[Andy Stephenson]

Overlander give the option of 3 different types on most of their lipo packs.

XT60 (best)

EC3 (OK)

Deans (worst)

Thanks Andy, exactly what I needed.  Cheers

+ 👍 for Overlander for an extra £1 choose your plug and they solder it. Saves me a lot of grief. Excellent service.

Modelshop Leeds do the same if I ask them nicely (which I always do) often while I wait.

Look on Amazon, some makes there offer different plugs.

I avoid EC3 after a plane crash landed on takeoff. Fortunately the plane wasn't damaged, but on connecting EC3 plug it had pushed the socket partly out of the blue holder, and the vibration of the take off had caused it to disconnect. XT60 for me every time.

Or XT 90 anti-spark at 5S and over.

Not sure I entirely agree with "Deans is worst".

Yes they are hard to separate (= a good positive electrical contact?) harder to solder well but they are the smallest and lightest for a 50A rating as long as you buy proper Deans, not the copies.

Deans have a spring which can weaken and give poor contact, also difficult to undo with arthritic fingers. XT s  every time and you can score the case for extra grip

Not quite - the price includes a standard connector - it has been Deans for all the ones that I have looked at but maybe that changes for bigger batteries.  The +£1 is if you want a different connector.

 

So for the batteries I was looking at, Deans was included in the price but EC3 or XT60 were £1 extra.

 

BTW I quite like Deans although I have started to standardise o XT60.  Still use Deans on my AcroWot foam-E because the Deans are much smaller and the battery compartment is very cramped.

Unfortunately for me, I don’t think anyone supplies LiPos with Anderson Powerpole (aka Sermos) connectors pre-fitted. I’d love to be told otherwise though 🙂

My arthritic thumbs can't undo XT60s any easier than genuine Deans (which have springs which don't seem to weaken).  I still like Deans because of their small size, but am switching to XT60 for my models which use packs in parallel, to avoid the situation where a live connector is exposed while only one battery is connected.

I've seen 3rd party Deans that don't quite make connection and others where the spring has distorted, I don't recommend.

 I find Deans very inconsistent, some tight and some that will fall apart.

 

GNB come with XT connectors so and moving towards that form the EC3/5's that seen to be on the general way out

[i12fly]

XT every time for me, foolproof connection, but use a dummy piece in the plug/socket when soldering just in case you accidentally overheat it so the brass cannot move in the nylon.

If they are tight, just squeeze the pins slightly together in the male part.

I have Deans on everything. Agree with the above, not easy to solder, but small. 

 

Do buy the original genuine etc etc ie quality items, though.
