I assume you were unable to comprehend the part about ripple current and voltage spikes.
oh well.
better luck next time.
ORIGINAL: SyCo_VeNoM
Only theories I can even remotely come up with would be the connector melting, and the wire shorting, and opening rapidly. BUT with that much current they would friggin weld together.
Or the wire disconnecting, and opening and closing the circuit rapidly could spike it. BUT if CC put proper capacitors on their product that would not be an issue seeing they are there to absorb spikes...
This issue from a few different posts I've seen sprawled on a few sites is not unique to that ESC I've also seen the same issues on the 1/8ths.

Sad thing is reading your post made me really do that.
Pointless arguing with you seeing you know more than everyone else in the subject.
I hope you don't believe everything a manufacturer tells you to get out of them having to warranty an object.

Anybody that spouts off "ripple current" as a killer of speed controls clearly spends too much time on RCM.

Side note ripple currents are caused by inductive load aka motor having voltage applied & cut off, not the battery connector
For out local "expert"

ThunderbirdJunkie wonders if TDWM understands that FET switching speed and capacitor capacity has more to do with all of this than *ahem* ripple current.

RE: deans connectors on a 1/5th scale?!? lmao.
It looked to me as a quick glance that the dean's connector looked fine but I couldn't seem to see the other side one. I also noticed that you could see some gold where the motor connections were attempted to be covered with electrical tape. That is where I would want to look first if it was in my hands.
I have seen several times where the weakest link will desolder itself or burn. I didn't see that here in regards to the dean's, but I need more pics to give an accurate assessment in my opinion.

This was EXTREMELY entertaining to read through. Thanks to all who participated. BTW I'm with TBJ and Syco. Not trying to burst any bubbles. Thanks again! lol

RE: deans connectors on a 1/5th scale?!? lmao.
I have shorted my ezrun 60amp esc motor wires once and it lived through it, and the battery didn't puff ect nor did the esc get warm, only the wire got warmer. HW uses quality stuff.
I also shorted my ezrun 35amp by the tamiya plugs once and the battery got hot. ESC works fine.

RE: deans connectors on a 1/5th scale?!? lmao.
Hahahahahahahahahahahahahahahahahahahahahaha That guys dumb.
Even tamiyas teu104bk esc can handle voltage spikes.
When soldering on my deans the two connectors touched, and my battery happened to be plugged in (dont ask why).
It half melted the friggen solder joint where they touched and left a crater.. But esc... still worked.
Not now though 
i drive through puddle which was actually deep hole and esc smoked. Boooooo.

PS I'm with TBJ and Syco completely. If the current draw is too high for the Deans to handle, the Deans would melt worst case causing current to go back to the battery best case becoming a permanent "off switch".

If ripple current is caused by crap batteries, and ripple current destroys ESCs, why don't we hear of more Brushles E-Revos and E-Maxxes frying the ESC in stock form?

Yes, any high resistance spot will heat up, and melt, just like a fuse does. Actually the deans would be the fuse. But that is not the case here is it? This is a CCODC (clear case of defective controller) but the culprit *(manuf.) will never admit it and replace it.

here's an idea.
if you want CC to cover your escs under warranty, don't run crappy 50amp deans connectors in the first place!

Its actually off for ppl on that forum to attack workers from the ESC companies they usually believe them no matter how stupid the argument they throw out sounds.
I love how the one who worte on ripple currents starts saying higher capacity packs have higher resistance because they are 2 packs in one
He also says lower capacity packs provide more power. That statement alone shows he don't know what he's talking about.

OORRRRR because the manufacturers dont want to keep replacing high end broken escs so they will try to skimp out of it in anyway they can. Im not saying that castle is a sneaky bunch of people but if they can get out of paying you back a load of money for a 1/5 scale brushless system then they will, no questions asked, people get greedy when it comes to money, and with greed comes slyness.
of course!

When they were created (YEARS BEFORE YOU WERE BORN) there was no reason to test past 100a because NO electric power system could or would pull that much.

Just for the record, I'm an electrical engineering student (studying ripple current, transient spikes, power transfer and wiring losses at university).
I completly agree with TBJ and Syco - higher resistance connectors in the battery line will cause the ESC to get less voltage (due to the drop over the resistance). This will stress the ESC less. While it is true that higher resistance will slow the charging of the anti ripple capacitors, THIS WILL NOT DAMAGE THE ESC IN ANY WAY.
Under rated connectors CANNOT damage an ESC in any way - unless they are on the motor side and short out.

I've had escs split the heatshrink on the capacitors that are across the battery from heat due to excessive ripple current.

I got a degree in electrical engineering 7 or so years ago royal PITA to finish. Still have nightmares of integrals, and derivatives attacking me when I sleep [:@]

do ripple currents go counter clockwise in the southern hemisphere?
do ripple currents go counter clockwise in the southern hemisphere?
I laugh at the ripple current excuse, because I used 20C zippy packs in my 8th scales for YEARS without issue. That's with both Castle AND Tekin systems. I think noobs and experienced racers alike can have brain farts and/or push a system too hard. When the system fails, they simply CANNOT blame themselves. It must be a failure on the part of the equipment, the manufacturer or both.
