Capacitor problem with bullistorm 120 esc
 

Hi

Just got my bullistorm 120a esc and soldered the capacitor to the battery terminals of the esc. Now, I switched on my esc and heard a hissing from the capacitors. No smoke or smell. The capacitors did go warm which I found unusual.

I have soldered red to red and black to black, so what could be wrong?

Please suggest what do to. I suspect I'll need new capacitors but I can't understand why this happened. Maybe dodgy bullistorm stuff!

Hmm, sounds like they've blown. I assume you're talking about an electrolytic capacitor (big can like)? Normally the top pops open, if they have a proper vent.

Bin it and replace it with a new one. Watch out for the stuff leaking out of it, it's nasty!

Hi
 

Yes, 4 caps in a row covered in heat shrink! In fact when I pressed the rope I heard a little pop from one of them!

I will throw them away. I think the manufacturer got the wires the wrong way cos the fan with my bullistorm had to be pluged in the other way I.e. positive to negative!

Well I tried the esc without the caps and it seemed to work fine although did get warm quickly (presumably due to no caps?)

Where can I get suitable caps from and which ones do i need?

speed passion or hobbywing caps will do fine

i have two 60 a bullistorms and they are cheap copies , one of my fans died from me plugging it in the wrong / /right way first time (if you know what i mean :thumbsup:

i only run mine in mardaves 1 s powered dont think they will handle any more :woot:

wont buy any more but these are fine at moment

regards
