XT30U Male Connector Pigtail Power Wire with 100μF 16V Capacitor

This is a male XT30 connector fitted with a 16V 100μF capacitor to help filter out any voltage spikes.

Modern racing drone motors / ESCs are becoming more power hungry and this can cause problems for sensitive electronics like flight controllers and FPV gear. If you find it hard to tune your PIDs or have a noisy video feed, adding capacitors should help to improve things. A capacitor will absorb power spikes generated by brushless motor during braking and in this way will help remove electronic noise from your setup, which is the source of the problem. The result will be clearer video, less noise introduced to your Flight Controller, and a setup which overall operates better than a setup without a capacitor.

Indications that your quad my benefit from a capacitor:

• Quad oscillations that can't be tuned out with PIDs
• Noise in your video feed when the motors are spinning
