ESC cap's size

4th_Dimension · Oct 22, 2020

Good evening all,
So I am doing my build and upon reading spec's for my ESC's the Manufactures states that i should use 220uF - 330uF low ESR capacitor per ESCto absorb BEMF switching noise and overall better flight performance.
What if I went just a little higher then the 330uF low ESR capacitor per ESC? Any thoughts or recommendations?

Thank you for your time,
Brian

You can go bigger with no issues, a little more capacitance in this use case will not hurt anything other than size and weight, which should be negligible.

As far as I know the bigger the better. Also if you use a higher voltage cap it also increases the capacitance. I fly 6s and I use 50v 1000uf caps on all my 4 in 1 esc’s.

Thank you guys for the needed information.
I don't fly (4in 1) ESC's. I have 4 individual ESC's. So I am thinking up go to 470uf/35v each OR I could go 1000uf/35v. Maybe over KILL 1000uf/50v.
