Adding a HV power capacitor to the MM esc - 03.02.2008, 02:59 AM

I got a few of the HV Power Capacitors from previous Novak HV esc I had. Would adding one or two off them to the MM be okay? On the searches I did most of the caps talked about the µF was around 300µF. I don't know what µF means or relates but the Novak ones I have are 2700µF.

These are the ones I have.

Copied from novak.com
HV/Super Duty Power Cap Harness: 2700µF (#5674)
This is the direct replacement power capacitor for the HV Brushless ESC and Super Duty XR ESC. The power capacitor is harnessed to 16 GA power wires and easily solders onto the ESCs solder tabs. Use of the power capacitor is necessary with the HV and Super Duty ESCs to dissipate noise and smooth voltage spikes, and will also improve the performance of these speed controls by reducing the operating temperature by 10-15 degrees Fahrenheit. This power capacitor can also be used with other high-voltage 10-14 cell ESCs for improved efficiency. Includes one, pre-harnessed high-quality, 25V electrolytic capacitor and double-sided mounting tape.
Note: This module is compatible with high-voltage ESCs only. HV/Super Duty Power Cap Harness: 2,700µF

I thought about adding at least one to the mm esc in the flm maxx and the e-revo. Lower the temp 10 - 15 degress is going to be a plus come this summer.

I was thinking about installing them the way BrianG says to do in this thread.

Don't know if this matters the mm's, on 4s, in evo - Neu 1515 1y and flmmaxx - HV4.5
What do you think?

Thanks for the link. That's the one that got away. I got caught up (and confused) reading the other ones from the search and didn't even see the one I needed.

Yeah that helped out. I didn't see it before cuz I was only searching the brushless forum. I need to get out of the brushless forum more often.

I added 4 caps in parallel for a total of 1760 uF, thanks to Brian.... it was what my friend had in stock so I grabbed them. it works wonders. I'll give props to anything that is cheap and effective.

also read the thread on adding a resistor to charge the cap. I still have to get to a supply store for one. I give up on opening old electronics now. I haven't found a single resistor!!
