Fried the great HV110!!!

[lutach]

Well, things are not going my way. Here is a close look at my CC Pheonix HV110.

The great HV110 seems not so great now. What will CC say about this? I was only using 10 A123 cells. Inmagine what would have happened on 12S lipo.

Wow, that's a nice ESC too! Let us know what CC says about that. I assume this was in a truck? Were you using ESC brakes? Just curious why the "flight" ESCs are cheaper than the car ESCs of the same ratings (like the Quarks)...

What were you running that in and with what motor? The HV110 is a nice controller and will handle high voltage, but it's current draw rating isn't that impressive. I believe that it is only rated to 110A continuous and I'll bet that the max current handling isn't much more than that, with this particular controller. The application for which this controller was designed will hit over 100A but the spikes aren't there like they are when used in a truck or car. Even the MM will handle up to 300A spikes, IIRC and so will the Quark.

Were you using motor braking or did you have mechanical brakes?

I was using it in my truck with a Hacker C50-XL or the ION-X motor and 10 A123 cells. The brake was off. I did run the truck 2 days ago for a sort test and it ran fine. Man this is just crazy. My Kontronik Jazz 55-(Something)-32 stopped working, but it lasted longer than the HV110. My Kontronik 40-(Something)-32 only blew the capacitor, but it also lasted longer than the HV110. The BK 3695 cogs like crazy, but it will go back in the truck. I was hoping to see my truck go around 80MPH or so. I can only beg CC to sponsor me with one of those SHV controller. That way I can wire my DeWalt packs in series and see what 72 volts fells like. LOL.

AAngel,

You mentioned IIRC. Is that a ESC or something else?

[jhautz]

IIRC = If I Remember Correctly

[BP-Revo]

Well, I always thought it was If I Recall Correctly, but same difference lol.

As for the ESC, the Plane controllers have a very low surge/spike rating. They can handle decent continuous counts, but they can't handle much more than that. That is also why they can't have brakes. Brakes cause the voltage to spike and that is what usually blows stuff (not the high voltage itself).

So, this is why car ESC's are so robust compared to boat and plane controllers - they must be able to hold up under braking.

I'm sure Castle will warranty it.

I tought 100 amps would be enough for the truck.

100A is fine for a continuous current rating, but when hitting the throttle hard from a standstill, doing wheelies, etc. cause current spikes that can hit over 200A for a short time. That is just my understanding from talking to the guys at Castle and stuff. Unfortunately, we haven't been able to get any accurate graphs from anyone, because the eagletree (which is what most people have, if they have one at all) only goes up to around 120A. The Quark Monster Pro, for example, is rated at up to 300A spikes and that's a 1/10 scale controller.

What did you have your "current limiting" setting at? I have mine on the Option 2 (sensitive), though now I might go the the Option 1 (very sensitive).

The owners manual says that the warranty doesn't cover over current. So he might be on his own here.

You can get the sensor that will got up to 300amps and 50v for the Eagle Tree but it's $130.

[lutach]

That kind of explains it, but I don't think I was actually using all 100AMPs. I mean 100AMPs is alot of AMPs.

[BrianG]

No, I think they're saying the pulsed amperage was what caused the issue.

Yeah, that's what I'm saying anyway. If you were running a 1/8 scale anything, I'll bet that you hit over 100A quite a few times in surges.

[lutach]

Ok. Now I have a Schulze 40.160, do you guys think I'll have any problems like the one I had with the HV110?

A Schulze? Maybe, maybe not. I don't own a Schulze, but many here have reported the Schulze letting the smoke out for no apparent reason. Did you just go and order that? That's a mighty expensive controller just for running in a truck.
