Better ESC power caps?

[ReddyWatts]

Any one using these Novak power cap MODULES on your boat controllers? I like the voltage spike suppressor that provides more ESC protection.

The biggest they have is only rated up to 6S

They have them for different applications, which makes sense for better protection and performance.

Yes, I know. I went there and read the specs on each of them. As I said, the highest voltage one is only for 6S lipo.

Reddy, this is a very good find. It makes sense now that Novak is likely finding that r/c cars in high performance mode are experiencing high ripple current and transients. What doesn't make sense is that marine SC's, which always traditionally see these peaks don't already have these features, particularly transient suppressors, built in. Are you listening, marine SC makers ?

nice find,

If enough of us try to 'educate' the ESC makers, maybe they will listen. I don't think any of them fully understand the stress an ESC is subjected to in use!

Very interesting, but wouldn't the use of additional capacitors across the battery input leads to the ESC (like many of us do) be considered 'decoupling capacitors' also?

Could it be that the use of these smaller 'decoupling capacitors' for RFI reduction in the Novak be needed due to the close proximity of the rx in rc cars? (brushed motors)

I hope someone buys one of these and lets us know the components and values used.

I think we can use Novak anti spike circult with diff caps higher voltage for HV esc are we?

[ReddyWatts]

Dont know what voltage they are clipping the spikes on the different modules. Could ruin your batts if it is to low for HV.
