Readytosky XT90 Connector Set (Male & Female) – High-Current Heavy Duty Interface
Power your high-performance RC builds with the Readytosky XT90 Connector Set. Engineered for large-scale drones, high-voltage multicopters, and heavy-duty RC vehicles, the XT90 is the industry standard for systems that demand massive current delivery without the risk of heat-related failure.
Molded from high-temperature, flame-retardant nylon, these connectors feature 4.5mm gold-plated bullet pins that ensure maximum surface contact and minimal resistance. Whether you are running a 6S racing rig or an industrial-grade cinelifter, the XT90 provides the secure, "clatter-free" connection required for high-vibration environments.
Key Highlights:
Massive Current Capacity: Built to handle a constant 90A current with burst capabilities up to 120A, making them ideal for high-torque brushless motors and large LiPo packs.
Easy-Solder Design: The pins feature a "half-cup" soldering terminal, making it significantly easier to secure thick gauge wires (up to 10AWG) for a professional, low-resistance joint.
Spark-Resistant Geometry: Designed with deep-recessed terminals to prevent accidental short circuits and provide a tight, friction-locked fit that won't vibrate loose during flight.
Polarity Protection: The distinct asymmetrical housing ensures that it is physically impossible to plug your battery in backward, protecting your ESCs and flight controllers from catastrophic reverse-polarity damage.
Premium Conductivity: High-grade 4.5mm gold plating prevents oxidation over time, ensuring your power delivery remains consistent even after hundreds of plug cycles.

Pro-Builder Tip:
Because the XT90 handles such high current, we recommend using high-quality 10AWG or 12AWG silicone wire. Always use heat shrink tubing over the soldered terminals to ensure total insulation against the carbon fiber frames of your drone.
Partsbaba Quality Assurance: All Readytosky connectors are 100% genuine and original. We provide a 14-day replacement warranty against manufacturing defects, so you can build your high-power systems with complete confidence.
