The point of this product is to have something to solder your capacitors onto in order to make it easier to securely and effectively solder thicker wire to the capacitor legs. These little things have become all but required for builds and really do make life easier and improve capacitor performance.
This is the third version of the Cap Cap. You would think there isn’t really much to this little thing to improve upon but this is a genuine improvement. Through copious amounts of testing, the designers have found that the improved conductance of the more robust traces surprisingly does improve often finicky capacitor performance.
The best way to use a capacitor is by soldering a minimum of 18awg wire onto the legs of the capacitor as close to the body of the capacitor as possible. Then soldering the wires directly onto the battery in pads of the ESC/AIO with a wire length no more than about 1” or 25mm.
The use of the Cap Cap and a good performing capacitor such as the Panasonic FM series or better is STRONGLY encouraged. Bad things can happen without good and effective capacitance. Bad things don’t always happen but they can.

Description from manufacturer:Are you tired of trying to solder wires on those pesky little capacitor leads? Step your builds up a notch with WaFL’s Cap Cap. This tiny PCB sits on the bottom of most standard “LOW ESR” capacitors, and provides you with two easily accessible pads for quick and clean soldering to the capacitor. Whether you need to quickly swap a broken capacitor after a hard crash, or simply don’t have enough room near your battery pads for your cap to cleanly rest, the Cap Cap makes attaching a wire to your capacitor simple, letting you mount it anywhere on your frame. Comes in a set of 5!
Ordered spare waFL capa cap. They work perfect for installing capacitor and back up incase you accidentally snap one off. You have a place to re solder to . Plus also perfect for adding cap to your battery leads next to xt30 and xt60
The capacitors appear to be quality and work as expected.
I put one cap on my battery pads on my AIO FC. I put the other one on my voltage and ground for my Caddx Vista. I have had zero issues with my HD video and zero issues with my FC. Going without caps definitely allows issues to happen. I like that these are smaller than the more common 1000uF caps. The flexible leads are an upgrade from the stiff legs you usually find on the caps.
I appreciate the size and length of wire. Only complaint is that out of the box, the wires are soldered with the some extra length coming off the PCB, making them a pain to bend and sit flush when taping it to an arm. Had to resolder.
