On the 90 size use the castle bullets for the E5 you should be fine shaving them down to fit

Thanks Tommy if Zi use the CC billets then I'd have to have the female CC on batteries as well no? What mm bullets do I need to fit EC5?

Well here is a fun fact.

There are 2 types of Ec5 connectors
1. Type that you push through from the top after you solder and
2. Type you slip casing over the wires, solder bullets on and pull the casing up until it pops.

Bad news is I have the second type that does not fit over the wires therefore I can't use.

I have always used the Eflite EC5s. They are strong and the wire cup will easily hold 8 awg wire.

You read my mind Chris I was just researching what brand offered what..  thank you. Do you file down the wires on your ESC's to fit the bullets?

I won't use Eflight EC5s since I had the little springs on one of the male connectors fail. It looked like they were burned to a crisp from arcing of my 12s batteries. Half the diameter of those little springs were just broken off at the top of the plug. I don't think those little springs are up to constant arcing of a 12S system. If you want to use those Eflgiht EC5s with 12S, you probably ought to rig up an anti-spark system.

Progressiverc.com has EC5's that have a solid male connector that is slotted lengthwise for the friction hold. This is the same basic design that Castle uses on their bullet connectors. I am going to be using the EC5's from progressiverc from now on.

Does CC offer bullet connectors that fit into a EC5 ? If so which ones will work? I plan on using 6s either 3850 or 4400

I have never had any trouble with them failing. But I have seen the progressive ones too.

As for getting the wire into the cup. The esc manufacturers tend to put way too much solder on the wires when they Pre tin them. I normally cut the battery wires down to length that reaches without pulling but isn't overly long. This helps with voltage ripple.

If you need to keep the wires long, just cut the Pre tinned part off and redo it yourself. Just make sure you get good penetration into the wire core. A poor soldering job will increase resistance and cause the plug to heat up and could cause issues.

Good penetration into the wire core? Meaning get the solder way down into the wire?

Make sure the solder penetrates into the core of the exposed wire. Don't need to let it wick way up into the wire. That will make it hard to bend and flex.

Picked up the Horizon Hobby EC5 connectors and I can't believe how much bigger the bullets are than what I had, plus these can be popped into the casing versus pulled. I hope this helps someone else. Thanks to those who shared their knowledge with me !

I thought about the EC5 but will probably go with the PRC6 now.

One thing I do to help with soldering the larger connectors and wires is use a wooden block with a hole drilled in it that the connector pin can sit down in while soldering.  The wood is an insulator so it won't sink heat out of the connector while you're soldering.  You can solder the larger connectors, this way, without having to use  really high heat or having to wait so long for the solder cup to come up to temp.
