I am going to be buy stuff here soon and was wonder what everyone was using. This will be for 10s and 12 or 14s systems. Was not sure if I wanted to continue with deans.

Thanks,
Chris

EC5 100%, solid connection, easy to solder, solid throughput and simply reliable.

I also use the bullets from EC5 s' for the Motor and ESC ends as well on all my large helis and they work great.

About the only thing I buy from Hobbyking really, buy a bag of 100 or so pairs and you'll be good for awhile.

I myself use Anderson Power Poles, and will not use anything else on the big ones.

But read the thread above, gives lots of good points to many different connectors.

EC5 all the way. So easy to solder and spark contained.

I've been using 4mm bullet connectors on all my large 50/90 E-Heli's for +6 years now, no problem. I have found that these make parallel or series connections very easy. To protect the male ends during transport I slip on a 4mm plastic bodied crimp connector over it.

I place the connector in a hobby vice and use a mini torch to solder/install the bullets and then use colour-coded heatshrink over each connector. Personally, I prefer this to the EC-5 plastic connnector covers which are not colour coded and need to be split in order to allow series connections, and do not allow parallel connections. Only takes me ~5 min to install a set of these btw.

I always have used spark arrestors (built-in on my 90 E-heli PowerJazz escs) and have never had to replace a connector so far.

The problem with 4mm bullets is that most of the newer large +30C packs come with 8g wire. This requires me to trim the tinned lead like a dull pencil tip in order to solder it. Seems to work ok but I'm sure that one day I will 'bite the bullet' (so to speak) and go to larger 5-6mm bullets.

The problem with changing over connectors on your fleet is that you need to change 'everything', including charger outputs and esc leads. This is a pretty big time consumming job (not too expensive though). So my advice to you is to go to larger connectors than you think you need right off the start. If I was starting over right now, I'd go to 6mm bullets. I'd probably use these for esc/motor leads as well.

Hope this helps.

Cheers,
TomC

+ One EC 5's
I made the switch to EC 5's also....the larger wires on the batteries made a pretty tough job of making a Deans look good....
Have had no problems with making up any combination type connectors from these either. I have made up all my series and parallel connectors from these along with all charge cords... very clean and easy... have been using them now for about 3 seasons and have not had a problem with any of them....
I do use the EC 3's on the smaller batteries... 3s and down....anything above gets 5's....

One other advantage is that they are easier to pull apart when the old artheritis is acting up!!!!

+1 on EC5's.

Make sure whatever you decide on is polarized, i.e. it will not let you plug it together backwards. That's the risk of bullets. All you have to do is be distracted one time while you are plugging things together and you get an instant weld followed by a probable fire.

Sounds like the EC5 connector is the way to go. Thank you everyone.

EC5 can still be damaged by the spark, just that it isn't exposed so you don't see it.

Whats wrong with good old bullett connectors.
I use 5.5mm on all my electric models, L400 up to TDR.
simple to wire in series for 12S packs, and pretty idiot proof to solder correctly as well.
Just my 10 pence worth (or 2 cents, depending which side of the pond )
