XT90 to QS8 AntiSpark Battery Adapter Cable | 8AWG Preassembled
XT90 to QS8 AntiSpark Battery Adapter Cable — Preassembled & Ready to Use
Stop rewiring your RC aircraft or battery-powered equipment just because your connectors don't match. This CACAZI QS8-S Male to XT90S-F Female adapter cable gives you an instant, clean conversion between QS8 and XT90 connector systems — no soldering, no guesswork, no temporary workarounds. Made in Mainland China.
Key Features
- Exact Connector Conversion: The QS8-S male to XT90S-F female configuration bridges your battery and equipment without replacing the equipment-side plug — keeping your build tidy and intact.
- Built-In AntiSpark (Sparkproof) Design: Integrated resistor on the XT90S-F female end significantly reduces arcing during connection, protecting your equipment and connectors with every plug-in.
- Preassembled & Ready Out of the Box: Both connector ends arrive fully joined — simply plug in and go. No assembly or soldering required.
- Heavy-Duty 8AWG Silicone Wire: Flexible, high-strand silicone wire rated to handle high-current applications with ease, maintaining bend flexibility even in tight builds.
- 200°C Heat-Resistant Wire: The silicone wire insulation withstands high operating temperatures, ensuring safe, stable performance during demanding power delivery sessions.
- Durable PVC Outer Construction: A PVC outer covering protects the wire harness, providing a neat and robust finished assembly.
- Compact 9cm Length: The short ~9 cm (3.54 inch) cable keeps your power path direct and minimizes resistance, ideal for use in aircraft models and RC vehicles.

Frequently Asked Questions
Q: What does the AntiSpark (sparkproof) feature on this XT90 to QS8 adapter cable do?
A: The integrated resistor on the XT90S-F female connector pre-charges the capacitors in your ESC or power system before full current flows, dramatically reducing the arc (spark) that occurs when plugging in a high-capacity battery. This protects both your connectors and downstream electronics from wear and damage over time.
Q: Is soldering required to use this QS8 to XT90 adapter cable?
A: No soldering is needed. This adapter cable comes fully preassembled — the QS8-S male and XT90S-F female connectors are already joined to the 8AWG silicone wire, so you can plug it directly into your RC aircraft, drone, or battery-powered model right out of the box.
Q: What equipment is this XT90 to QS8 adapter cable compatible with?
A: This cable is designed for RC aircraft models, drones, and other battery-powered equipment that use either a QS8 or XT90 connector system. Always verify that your battery and equipment connectors match the QS8-S male and XT90S-F female configuration, and confirm correct polarity before connecting.
