The EC5 connector is a type of electrical connector commonly used in the radio-controlled (RC) hobby industry, particularly suited for applications requiring a robust and reliable power connection. It's designed to handle high currents, making it ideal for larger RC vehicles and other demanding applications.

Key features of the EC5 connector include:

• Current Capacity: EC5 connectors can handle up to 120 amps of continuous current, making them suitable for high-power applications.
• Size and Design: The connectors feature a 5mm bullet diameter, which helps accommodate the high current flow. They are typically encased in a blue plastic housing that helps prevent short circuits and ensures that connections are made with the correct polarity.
• Safety and Ease of Use: The design includes a genderless housing which makes it easy to connect and disconnect without worrying about male or female parts, enhancing convenience and safety. The secure connection also prevents accidental disconnections under load.

EC5 connectors are highly valued in the RC community and other hobbyist areas for their durability, reliability, and ability to handle significant power levels efficiently. They are often used in scenarios where smaller connectors like the EC2 and EC3 would not suffice due to the power requirements.
