Fantom FR-10 Pro ESC Power Capacitor

Five stars in appearance and intended function, ZERO stars in actual construction. The capacitors are polarized electrolytics, and obviously have a right and wrong polarity. Both wires are BLACK (lol) and with the capacitor pack heat shrinked (mine was heat shrinked in black, not clear as pictured, there's no way to tell which wire is positive and which is negative. 50/50 chance you'll get it right, and if you don't, you'll be greeted with a nice little puff of magic smoke. I expected better out of Fantom.

Use the picture shown here with the product to determine the polarity of the capacitors. The pack works well for a small lightweight cap pack and Fantom customer service was helpful. Mine were also shrink wrapped with black wrap so it took a bit more work to determine the polarity of the wires.
