Amass XT90-S Anti-Spark Male Connector

The genuine Amass XT90-S male connector adds anti-spark protection to the XT90 interface, absorbing the inrush current when a high-voltage battery is plugged in. That stops the loud spark and contact erosion that come with connecting 6S–12S packs on heavy-lift multirotors, cinelifters, X-Class quads and agri drones, and shields the ESC from the current spike. It is fully compatible with XT90 and XT90-S female connectors and is sold singly or as a pack of five.

Key features

• Built-in anti-spark: no add-on anti-spark module or resistor loop to wire in, so one less failure point
• Rated 500 V DC and 45 A with 10 AWG wire (Amass rating, temperature rise under 85 °C)
• 4.5 mm gold-plated brass contacts for low contact resistance and less heat under sustained load
• Polarised housing prevents reverse-polarity connection
• Clip-on soldering cover insulates the solder cups for a neat lead without bulky heat-shrink
