In this Power Tip Robert Kollman discusses a mistake designers make often and that is putting too much ripple current into a capacitor that may shorten its lifetime.
Nice video, then... it is recommended to select capacitors with less ripple current?

Ripple voltage is known
Ripple voltage is known as the fluctuation in voltage between the voltage source and the ESC. Ripple voltage if it gets out of control can destroy your ESC.
Ripple Voltage can be monitored within some ESC's internally. In this case you can get an entire data log of a run you make to be analyzed on your computer. This is where you are able to check in with your system.
While analyzing your run you want to be certain that ripple voltage does not exceed the maximum recommended value. If the ripple voltage exceeds the max value once within a run, it is highly recommended to make some changes to improve the value.
There a handful of ways that you can reduce ripple voltage. Anything from reducing load to adding a cap pack. The video covers all methods.

Article on Ripple Voltage and How to Improve it:
Great stuff as usual!
Friend, please ask me a question! on an engine that says 3s can i use a 4s battery if i use a 2 to 4s esc?
I have a question about ESC's is there a way to test an ESC for maximum voltage without destroying it? I have an existing ESC that is rated for 2S however many people have found that they can run 3S with it without any problems. However this seems to be luck of the draw. I really would like to hook up a multimeter or something and find out if the ESC I have actually can take 3S without just throwing a 3s battery on it only to find out I smoke the ESC. Please let me know if there is a simple way to test an ESC for max sustained voltage without killing it.
I'm a little confused...... If a higher C rating means MORE amps.... doesn't that mean MORE current? How would adding MORE help protect against too much? I'm not understanding this part.
If an ESC is 150amps..... and you're using a battery that can output 125 amps max... wouldn't that mean the ESC is safer than if the battery could output Amps EXCEEDING the ESC's amp rating?
