Few questions about ESC and batteries

[gadou]

I just received my Swordfish 220+ Pro.

There are four 4 capacitor on it. Do I need an extra bank of 4 between the ESC and the batteries?

Do I really need an anti-spark thing?

It will be used in a sport 40, with a Leopard 4082-B/2Y and two 3S2P 5600 mAh batteries.

Thanks for the help.

The spark is a good thing, it lets you know if the caps are going bad. I seldom use extra caps on my builds but many do. Correctly done it can add some extra protection for long wires or weak packs.

Thanks Fluid for the answer!

I use to race nitro about 10 years ago, took a break, and I'm building my first FE.

So this is new to me.

Thanks,
