QWinOut 5pcs XT30 Plug Pigtail Power Wire Cable 100F Capacitor for Happymodel Mobula7 HD Sailfly-X UR85 UR85HD Crazybee F3 F4 PRO Drone

  Item name: XT30 Plug Pigtail Power Wire with 100μF Capacitor Wire length: 70mm(include xt30) Height: 2.6 gram /Piece Used for :  Crazybee F3 / F4 PRO series flight controller Quantity: 5 Pieces Can avoid the risk of burning the mosfet or the 5v regulator at the moment of power on With this Capacitor , we can use 3S 300~350mah battery for the Crazybee F4 PRO V2.0 and Crazybee F4 PRO V2.1 , and 2s 300~350mah battery for the Crazybee F4 PRO V1.0  And if you want to use the battery above 350mah , we recommend use 220 μF or above capacitor.
