Let me try saying this a different way.
I realize that castle makes 6.5mm connectors (and that you have exceeded the rating of them) - but they ALSO make 8mm bullets that are rated at 300 amps. I realize they do not come in a plastic housing, though. Because the "EC8" you posted has no amperage rating that I can find (doesn't mean it isn't out there) I would be inclined to try to fit Castle 8mm Bullets in those housings "EC8" housings. Great bullet, and a housing that keeps you safe.
In addition to what Castle makes. Anderson Power Products makes some very nice connectors (though only the 35-75 amp "Sermos" are marketed to the RC crowd) that are rated at up to 350 amps. I don't know if they would be physically too large for you.
The reason of asking how many amps you need is because in the Anderson family, there is a large jump in physical dimension between a connector rated at 240 amps, one rated at 300 amps, one rated at 350 amps, and one rated at 450 amps.Last edited by FormulaZR; 04-22-2015, 09:36 PM.Comment

They don't look bad: http://www.andersonpower.com/products/multipole-sb.htmlWhy are you bothering me? I want to see your boat!

The ose ones appear to be the same ones as Progressive RC;
They are rated at 300 amps;
"Our connectors are constructed from the highest quality materials to ensure you get the best connection every time, whatever your application.
Ideal for heavy-duty applications requiring up to 300 amps of current, and able to easily handle 6 AWG wire, these are the largest shrouded connectors available, combining safety and high performance."

Good find. They do look alike.The ose ones appear to be the same ones as Progressive RC;

Look at the customer pic on that page. Lol
What the heck is going on there?!? Lol

Travis....are you sure that you need to go to an 8mm connector? Are you going to re-lead all your Revo's with 8 or 6 ga wire to the cell tabs? At this point 8mm are not really necessary. You may want to call Castle or progressive rc and find out what the corresponding voltage is for there max amp ratings on the connectors?? If it is 12S, then you would be ok to 320amp or so on your 6.5mm an 8mm would be good to 450 if you are running 8S, it is all relative to the voltage, and i can assure you that the rating that are provided are not well backed by science, and it is more marketing than anything. They should technically be rating with continuous wattage or power as opposed to current.
The APP connectors have way less meat to them and are rated at higher voltage and current, because those connectors are typically used in industrial applications and have to follow strict testing and codes.Comment

Better to have too much than not enough.

Better to actually know the facts, then to build off of assumptions.Comment

Here's what I do know....
1) my connectors get warm in the mono after a short run. (Red light right there if you ask me)
2) I'm pushing this setup pretty hard, so it can't hurt (unless these aren't as good as what I have)
3) the rating on what I have is 200 amps. What cells, I dunno. I am pulling more amps than that no doubt.
4) I already have some on the way
As I always do, there will be a back to back test.
Here's some wire gauge info. http://www.zrd.com/faq/esdfaqwiresize.html
Looks like at the length we have in out boats, 10ga is sufficient at short lengths. I can resolder 8ga wire on my batteries if it was needed. I'm going to contact john a revo and ask him if he'd do it on the next set of batts I order. I'm pretty sure he will if the carry that size wire in stock. He's done it for me before.32" carbon rivercat single 4s 102mph, 27” mini Rivercat 92mph, kbb34 91mph, jessej micro cat(too fast) wasComment

I can say this, check out some really fast builds....I can assure you not many are using 6.5 bullets. If any at all are using them. Just sayin...
At this level I'm at now, I'll agree that it's better to have too much than not enough. Same rule I go by with almost everything I do. You can tell this by most of my builds. Pretty much every one has more motor and Esc than it needs. Better to over do it than under do it. You know this too.....32" carbon rivercat single 4s 102mph, 27” mini Rivercat 92mph, kbb34 91mph, jessej micro cat(too fast) wasComment

This is not true at all. Amps are amps, and 100 amps through a conductor creates the same amount of heat at 7.4v as it does at 44.4v, that is why there are no wattage ratings. An 8mm that is good for 300 amps at 12s is still only good for 300 amps at 2s.
Though it is questionable about how they are rated, because it also depends heavily on the type of solder that you use(and how well you solder), as that will be the point of failure, and also the duration of that current bursts and the length of the run.Last edited by kevinpratt823; 04-23-2015, 12:45 PM.My private off road rc track

Lets consider the connector/solder a fuse for a moment. Fuses are rated at a maximum voltage, primarily for it's insulation. A 300VDC/100 amp fuse still blows at 100 amps @100VDC.
FYI, the chart you posted is primarily concerned with voltage drop Travis, not how much current the wires can handle. The higher the load and the longer the distance the less voltage you end up with at the load. What it is telling you for example, is that with #10 @24v, you can have 696 Foot-amps and still maintain only a 3% drop in voltage at the load. So at 200 amps you can go 3.48' round trip and only lose 3%(.72v) volts at the load, but the chart also clearly states that the rated ampacity of that wire is only 60 amps(regardless of voltage) for 105 deg C rated wire.Last edited by kevinpratt823; 04-23-2015, 02:17 PM.My private off road rc track
