Overview

Upgrade Your Power Connection with XT90‑S Anti‑Spark Extension Cable

The XT90‑S Extension Cable is a premium‑grade power connection solution designed for high‑performance RC models, drones, UAVs, and electric vehicles. Featuring genuine Amass XT90‑S Anti‑Spark connectors with 10AWG ultra‑flexible silicone wire at 50cm length, this cable delivers reliable, spark‑free power transmission for demanding applications.

Whether you’re connecting your LiPo battery to an ESC, charging your drone batteries, or building a custom power distribution system, this extension cable ensures safe, efficient, and durable performance every time.

Key Features

⚡ Anti‑Spark Technology – Protect Your Connectors

The XT90‑S is the **upgraded version of the standard XT90 connector, featuring a built‑in resistor that prevents dangerous sparks when connecting power. This two‑stage connection design eliminates the “pop” and flash that can damage connectors over time, extending the lifespan of both your cable and your equipment.

🔌 Genuine Amass XT90‑S Connector – 100% Authentic

Each cable is equipped with 100% genuine Amass XT90‑S connectors – not cheap knockoffs. The 4.5mm gold‑plated banana plugs ensure solid, reliable connections with low contact resistance and excellent conductivity. The high‑temperature nylon housing withstands extreme conditions, while the gold‑plated spring pins maintain consistent pressure for thousands of insertions.

💪 10AWG Silicone Wire – Heavy‑Duty Power Delivery

The cable features 10AWG (5.26mm²) stranded tinned copper wire with ultra‑soft silicone insulation. This combination offers:
- Low DC resistance (≤3.28 mΩ/m) for minimal power loss
- Exceptional flexibility – bends easily in tight spaces
- Wide temperature range: -60°C to +200°C
- High current capacity: 90A continuous / 120A peak

💧 IP67 Waterproof & Durable Construction

The nylon housing and sealed silicone insulation provide IP67‑level protection against dust and water immersion, making this cable suitable for outdoor and wet‑environment applications.

🔥 High Temperature Resistance

Built with high‑temperature nylon and silicone insulation, this cable maintains performance even under extreme thermal stress – perfect for high‑current, high‑heat applications.

Installation Tips

⚠️ Important Usage Notes:
> 1. Polarity Check: Always connect Red to Positive (+) and Black to Negative (–) to avoid short circuits.
> 2. Two‑Stage Connection: The XT90‑S features a two‑stage anti‑spark design – insert slowly to allow the built‑in resistor to pre‑charge the circuit before full engagement.
> 3. Secure Connection: Ensure the connector is fully inserted until you hear/feel it click into place.
> 4. Cable Management: Avoid sharp bends near the connector base to prevent stress on solder joints.
> 5. Not a Magic Fix: While XT90‑S reduces spark damage, it does not fix undersized wire, poor solder joints, or excessively long cable runs.
