XT90S-F (Female) Amass Anti-Spark Power Connector

XT90S-F (Female) by Amass is a genuine, high-current power connector integrated with patented Anti-Spark technology. Engineered specifically for interfacing high-voltage battery packs with ESCs and PDBs on heavy-lift FPV drones (6S–12S+ LiPo setups), electric vehicles, and robotics platforms.

The standout innovation of the XT90S design is its two-stage stepped contact architecture with an integrated pre-charge resistor. Upon connection, the resistor engages first to smoothly equalize current and charge the ESC input capacitors, completely eliminating the electrical arc (spark). This prevents contact degradation, extends connector lifespan, and safeguards delicate flight electronics against voltage spikes. Encased in high-temp flame-retardant nylon with gold-plated brass spring terminals, it maintains reliable low-resistance power throughput up to 90A continuous (120A burst). Includes a protective snap-on sheath, eliminating the need for heat-shrink tubing.
