Overview
The Etronix EC3 Connector Extension Adaptor (ET0703) is an essential accessory for RC enthusiasts who need to extend the reach between EC3-equipped components in their RC models. Whether you operate RC cars, trucks, boats or aircraft fitted with EC3 connectors, this simple yet effective extension lead provides a practical solution for improving your model's wiring layout and accessibility. The EC3 connector standard has become increasingly popular across the RC hobby in the UK and worldwide, making this adaptor a valuable addition to any RC enthusiast's toolkit.
This handy extension adaptor is ideal for tidier layouts and easier access to your RC model's critical components. By extending the distance between EC3-equipped batteries, electronic speed controllers (ESCs), and charger leads, you can reduce strain on connectors when space is tight or components are mounted further apart. Whether you're positioning a battery in a remote location within your RC car, connecting an ESC to a distant battery bay, or managing charger connections, this EC3 extension adaptor provides straightforward, plug-and-play convenience from Etronix, a trusted RC electronics brand recognised throughout the RC hobby.
If you're building a ready to run RC model in the UK or customising an existing setup, proper cable management and connector health are crucial for reliable performance and safety. This extension adaptor helps you achieve neat, professional-looking installations whilst protecting your connectors from excessive stress and strain during use.
Key Features
- EC3 Connector Compatibility — This adaptor is specifically designed for RC models and components equipped with EC3 connectors, ensuring a secure, reliable connection that maintains the integrity of your RC car, truck, boat or aircraft electrical system.
- Approximately 100mm Length — At around 100mm in length, this extension lead provides sufficient reach to separate components that would otherwise be positioned close together, improving cable management and reducing physical stress on connector pins.
- 16 AWG Wire Gauge — The extension is constructed with 16 AWG wire, providing appropriate electrical capacity for typical EC3 applications whilst maintaining flexibility and ease of routing through tight spaces in your RC model.
- Plug-and-Play Installation — Simply connect one end to your battery, ESC or charger lead, and the other to your component, with no soldering or modification required, making installation accessible to RC hobbyists of all experience levels.
- Reduces Connector Strain — By extending the physical distance between components, this adaptor minimises the mechanical stress placed on connector pins and housing during normal operation, extending the lifespan of your equipment.
- Supports Practical RC Wiring Layouts — Whether you're tidying up a cluttered RC car installation, creating a more balanced weight distribution by repositioning your battery, or simply improving access for charging and maintenance, this adaptor helps you achieve professional-standard layouts.
- Trusted Brand Quality — Manufactured by Etronix, a recognised name in RC electronics, this adaptor has been designed with the practical needs of RC modellers in mind, ensuring reliable performance across a wide range of EC3-equipped applications.
Technical Performance
The Etronix EC3 Connector Extension Adaptor is engineered with practical RC applications in mind. Constructed with 16 AWG wire, the extension provides adequate electrical capacity for typical EC3 connector applications whilst maintaining the flexibility necessary for routing through confined spaces within RC models. At approximately 100mm in length, the adaptor strikes a balance between extending reach and maintaining manageable cable lengths—though it's important to note that daisy-chaining multiple extension leads together to create longer combined extensions is not recommended, as each additional connection introduces resistance into the electrical circuit, which can impact performance and safety. The adaptor utilises industry-standard EC3 connectors on both ends, ensuring compatibility with the vast majority of modern EC3-equipped batteries, electronic speed controllers, and charger leads used in contemporary RC cars, trucks, boats and aircraft throughout the UK and beyond. The solid engineering and quality construction typical of Etronix products mean you can rely on this extension adaptor for consistent performance across diverse RC applications, whether you're running a brushless or brushed motor setup, operating 2WD or 4WD models, or working with various battery chemistries.

Frequently Asked Questions
- What wire gauge is the Etronix EC3 extension adaptor? — The extension is constructed using 16 AWG wire, which provides appropriate electrical capacity for typical EC3 connector applications in RC cars, trucks, boats and aircraft.
- How long is the EC3 extension adaptor? — The adaptor is approximately 100mm in length, providing sufficient reach to separate components whilst keeping cable management practical and neat.
- Can I daisy-chain multiple EC3 extension adaptors together to make a longer lead? — Whilst it is technically possible to connect multiple extension leads together end-to-end, this is not recommended. Each additional connector in the circuit introduces electrical resistance, which can negatively impact performance and safety. For longer extensions, it's better to source a single longer EC3 extension lead.
- What RC models can use this EC3 extension adaptor? — The adaptor is compatible with any RC model equipped with EC3 connectors, including RC cars, trucks, boats and aircraft. It works with EC3-equipped batteries, electronic speed controllers, and charger leads.
- Is the EC3 extension adaptor suitable for beginners? — Yes, absolutely. This is a simple plug-and-play accessory that requires no soldering, modification or technical expertise. Simply connect one end to your battery or ESC and the other to your component. It's ideal for beginners looking to improve their RC model's cable management and component layout.
- What is EC3 connector compatibility? — EC3 is a widely-used connector standard in the RC hobby, particularly popular for mid-range RC models and equipment. If your RC car, truck, boat or aircraft uses EC3 connectors on the battery, ESC and charger, this adaptor will work seamlessly with your setup.
