1000uF capacitor vs. 4700uF capacitors?

i would like to know if a bigger capacitor may improve the perfomance of the esc, or it can damaged it.

thanks

I'm almost positive you can go as large as you want, assuming you're talking about putting it between the battery and ESC without hurting the ESC.

The larger the capacitance (capacity or uF), the more electrons it can store.
It's a great way to store energy for starts and will also help with voltage fluctuations while running (filtering).

IMHO if you go too large, you'll hurt performance. It'll help with sudden draw just as well as a small cap, but will then take more charge to get it peaked while the car is running.

I personally run a single 470 uF cap between the battery and ESC. It's a great balance between energy storage, size, and filtering. The highest I would personally go is 1000 uF. 4700uF might be overkill and become parasitic in a way, in my humble opinion.

Yeah.... I think its useless to use bigger caps. The best cap is Low ESR type : fast charge and discharge ( usually you can find them in computer motherboard near CPU area ). I personally use 3300uF 6.3V type of capacitor. Honestly I don't feel any different with or without capacitor installed, but Novak said it helps ESC run cooler ??

The ultimate Low ESR capacitor is Tantalum Capacitor type : ultra fast charge and discharge.
