Default EC8 connectors?

There's been a space in the market for a reasonably priced high amp gendered connector for a while now, looks like the market finally responded.

From what I can figure out somebody in china made these, right now they sell for around $4-$5 per set but I'm sure HK will have them cheaper soon enough.

whats the amp ratings on this ones , looks as you have the housing throw the wire before soldering , and maybe the hole is for easier soldering

Looks like a few places sell EC8.. In the US, you can get 2 pair at LowerHeil for $9!

I like EC style connectors, I have not had and trouble with them. I have been going back and forth on which connector to use for super high current application. I want idiot-proof, like EC5.

I have now ordered Castle 6.5mm connectors, hopefully I will like them. 8mm even sound a bit to much, but it's very nice we now have an 8mm fully keyed connector.

Look closer, The housings are genderless. Also you can get that connector much cheaper at HK just look up "HXT 8mm", they all come from the same factory in china and are variously labeled as PRC8 or HXT 8mm and probably some other names too. They're of the same family as the 4mm "HXT4" plugs that used to come on a lot of HK batteries. I don't know if they have a real official name for that plug family, so many names are used for them that it's hard to tell.

EC8's have the females on one side and the males on the other and have specific ESC and battery side housings that are keyed so they can only be inserted one way.

I wonder why there is no low price gendered connector in 6mm yet, that's another open space in the market that nobody has filled yet. It seems like it would be simple for Amass to just release an alternate housing for the XT150 bullets.

I personally can't abide the Castle 6.5 connectors. I love their ESCs but the connectors suck. you have to spend way to much time fiddling with the "procedure" they suggest to snug them in, connect disconnect them....I mean don't we have enough to think about without dicking around with a connector. Not to mention the leads are far to close together for my comfort. I don't care about your terms for conductivity and you used to use wax paper between your wires and you never had any problems....If you look at one of those connectors the metal between the two leads is so close you'd need a micrometer to measure it. As opposed to EC 5s where there is a logical distance between conductivity. XT 90s are fairly decent. Just stay away from the Castles. Unless you like to waste time bending tiny metal connectors back and forth. EC 5s should work for most apps.

I can't imagine many users requiring 8mm bullet connectors.

I think an ec4 sized between the 3 and 5 would be a good seller.

That's called an XT90.

Yeah, I read this about them. Taking a shot anyway, I didn't invest up over the ears in connectors. EC5 is just not applicable for my use case, speed heli. The R5 easily pulls 120A on the straights, and the inside of the fuse is hot. I need to upgrade.

RC Proplus Pro D6 might fit the bill. The Pro D6 are technically genderless however you can set them up with the male bullets on the ESC side and the females on the battery side which makes them polarity protected and gendered - sort of.

Yeah, of course I have checked them out too. But there isn't a way too build them 100% bullet proof, is there?

Stuck with the same problem as Linus, speed helicopters and minimum space on the inside of fuselages, so I went with bullets. RCProplus 8mm bullets fit the bill perfectly. Easy to solder and super easy to wire up so that they fit inside the tight fuselages.

I've been using them for years w/o issue. Just build the adjustment tool and use a lubricant on the contacts. Once properly adjusted they do not require frequent readjustment.

Not that I'm aware of.

You'd think that Amass or sombody would have seen the demand for a reasonably priced "foolproof" 6mm connector and filled that space in the market. It seems like such an obvious thing, just scale up the EC5 to 6mm and yet nobody has done it yet.

Yay, scale up EC5, then they'll be an even bigger pain

Why do you say that? Just use open solder cups like the new ones HK recently started selling.
