Amass XT90-S Anti-Spark Female Connector with Housing

The genuine Amass XT90-S female connector builds an anti-spark system into the standard XT90 plug. It soaks up the inrush current when a high-voltage pack is connected, preventing the arc that erodes contacts and can lead to ESC failure on 6S-and-above heavy-lift multirotors, cinelifters, large fixed-wing models and agri drones. It is fully compatible with existing XT90 connectors and comes with a clip-on solder housing.

Key features

• Integrated anti-spark: no separate anti-spark module or DIY resistor loop, so one less failure point in the power system
• 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 in a high-temperature nylon body rated UL94 V-0
• Polarised shape rules out reverse-polarity connection
• Clip-on housing covers the solder cups for a neat, short-resistant lead; accepts 14–8 AWG wire
