If you're referring to the brown/orange colored chip that we see a portion of in your picture with a glob of solder on it's end terminal, that's a ceramic capacitor.

One word of advice on adding caps that are off-board, use as thick wire as you can. The purpose of the caps is to supply energy during those high demand moments (chang in acceleration such as immediate acceleration or immediate decel (i.e. braking)). If you use thin gauge wire, the wire will limit the amount of current the caps can provide and get more resistive.


Lutach -

The 90A version doesn't look like it has caps on it. Are there any?

Also, in your opinion, how do these compare to the Hobbywing ESCs? The HWs seem to use good components (at least for their output FETs) and are soldered pretty well (albeit in a ginormous sized package).
