Amass Polymax 5.5mm Bullet Female connector – GC5510-F.G

Product Description

The Amass Polymax 5.5mm Bullet Female Connector (GC5510-F.G) is a high-performance, precision-engineered power connector designed for secure high-current electrical connections in RC systems, drones, robotics, and advanced electronic applications. Manufactured by Amass, a globally trusted leader in professional-grade connector solutions, this 5.5mm bullet connector delivers excellent conductivity, durability, and stable power transmission in demanding environments.

This female bullet connector features a high-quality gold-plated brass contact system, ensuring superior electrical conductivity and minimal resistance during high-load operation. The gold plating significantly improves corrosion resistance, allowing the connector to maintain stable performance over long-term usage and multiple mating cycles.

Designed for high-current power applications, the GC5510-F.G is widely used in battery packs, ESC connections, and motor power systems where consistent energy transfer is essential. Its precision-machined 5.5mm interface ensures a tight and secure friction-fit connection with compatible male connectors, reducing the risk of disconnection even in high-vibration environments such as drones and RC vehicles.

The connector is housed in a durable, heat-resistant insulation body that provides excellent protection against mechanical stress, heat buildup, and electrical insulation failure. This makes it highly suitable for demanding applications where safety and reliability are critical.

Engineers and hobbyists prefer the Amass Polymax 5.5mm series due to its balance of compact size and high current-handling capability. It is especially popular in high-power RC setups where efficient energy transfer and low voltage drop are required.
