Quark fried, blown capacitor... - RC-Monster Forums

I just have to ask. If running all of these caps is so beneficial, why hasn't this been visited before?

It seems to me, that if there are so many benefits to running all of these caps, you could just solder small copper posts or bars on the rather large solder pads of the quark to accommodate four or so capacitors and then solder the battery leads to these bars.

As for the arcing, I run a junction box of sorts on my truggy and facilitates quick battery changes. The esc and battery connectors plug into the junction box to complete the circuit. If I run my fans from the junction box, the fans should drain the caps when I disconnect the batt and prevent the arcing when I re-connect the batt. Is that right?

Well, these small high power ultra capacitors are relatively new. Don't ask me why no one has tried it, as you can see, not very many ppl are interested in them. We won't know how well they perform in real-world unless someone tries it, I am.

As for your connector arcing, it WILL happen when there is no voltage in the caps, if they are charged, it won't happen. The Quark itself self discharges the caps, no need to do it. Your fans will only run for like a second.

Why nobody? I used them they are great but they are not cheap. Old link

hmm doesn't say that you are using ultra-caps. Which brand/series did you use, and what did you use them in?

same caps
I was using BPAK0058 E015 58F 15V on E-Maxx.

Oh, you were using one of their modules? IC How many caps total did it use? It shows 58F, but you would need alot of caps to get that, considering the series requirements for voltage. What setup did you have? Little more info?
