Specifically Designed For FPV Racing / 3D Helicopters! 

This is the RCPROPLUS D4 Supra X Battery Connector Set, including four full male/female connectors. Featuring a unique patented banana plug lock design, these D4 connectors securely lock in place, handling quick movements and vibrations, commonly found during extreme 3D flights, without coming apart. The stronger jacket and snaps extends the advantages of the previous generation of Supra X Connectors and makes them better.

These connectors are a great solution for your high current and high voltage demands offering a large, low resistance surface patch for efficient power transfer. The 24K Gold Plated bullet plugs feature a recessed wire cavity and solder windows making assembly hassle free, while the sheath uses high temperature capable, impact-resistant plastic imported from Japan.
