Overview
The Etronix Deans 3S Battery Harness For 3 Packs In Series (ET0709) is an essential accessory for RC enthusiasts who need to configure multiple battery packs in series to achieve higher voltage setups. Whether you're running RC cars, trucks, boats, or aircraft in the UK, this compact and straightforward harness makes it easy to connect three individual Deans/T-Plug fitted battery packs together, creating a 3S series configuration without the need for complicated custom wiring or soldering. This is a must-have component for anyone looking to streamline their RC setup and expand their power options.
Designed with the RC hobbyist in mind, this Deans 3S Battery Harness from Etronix brings simplicity and reliability to series battery configuration. The harness eliminates the guesswork and potential safety issues that come with improvised connections, giving you a professional-grade solution that integrates neatly into setups already using the popular Deans connector format. For RC car UK enthusiasts, RC truck builders, and anyone running multiple battery packs, this harness is an intelligent investment that will save you time and effort during setup and battery management.
The ET0709 harness is particularly useful for bench testing scenarios where you need a temporary 3S series arrangement, as well as for permanent installations where you want to maximise voltage and performance from your existing battery collection. With proper planning and attention to polarity, this connector assembly delivers the flexibility that modern RC racing and recreational flying demands.
Key Features
- Deans/T-Plug Connectors — The harness uses industry-standard Deans (T-Plug) connectors throughout, ensuring seamless compatibility with the vast majority of modern RC batteries and ensuring universal connectivity across your RC car UK collection without adaptor chains or unnecessary complications.
- Series Connection for Three Packs — This harness is specifically designed to connect three individual battery packs in series, allowing you to combine them into a single 3S configuration that delivers significantly higher voltage output than any individual pack, opening up new performance possibilities for your RC equipment.
- Compact and Streamlined Design — The harness features a compact footprint that helps minimise clutter and weight in your RC setup, making it ideal for space-constrained installations whether you're running off-road buggies, short-course trucks, or aerial platforms.
- Professional-Grade Wiring — Rather than attempting dangerous or unreliable custom soldering, the Deans 3S Battery Harness provides properly crimped and assembled connections that ensure reliable power delivery every single time you use your RC equipment, eliminating the risk of loose connections or intermittent power loss.
- Straightforward Integration — The harness integrates directly into existing setups with minimal fuss, working seamlessly with any RC applications that already use Deans connectors, whether you're running competitive RC cars or casual bashers.
- Safety Through Design — By using a purpose-built harness rather than improvised connections, you ensure correct polarity and connection order, significantly reducing the risk of damage to your ESC, receiver, or other valuable electronics.
Technical Performance
The Etronix ET0709 Deans 3S Battery Harness is engineered with precision and built to the standards expected from a recognised RC component manufacturer. The harness features quality connectors that maintain consistent electrical contact and reliable power delivery across all three battery connections. When properly assembled, the harness enables you to combine three LiPo battery packs of the same voltage and capacity into a single series configuration, significantly increasing the overall voltage output available to your RC system. This is particularly valuable for RC enthusiasts seeking to upgrade their vehicles' top speed and acceleration without replacing their existing battery collection. The connector design ensures minimal voltage drop and reliable performance during high-current draw situations typical of brushless RC cars and trucks. For optimal results and safety, it is essential to use battery packs of matching voltage, capacity, and similar state of charge. You should always verify that your ESC and electronics support the resulting voltage before connecting any series-configured batteries. Regular inspection of all connectors and wiring is recommended, and you should monitor battery temperatures during use to ensure safe operation and extend battery lifespan. The harness is particularly useful in competitive RC racing UK environments where consistent power delivery is critical, as well as in recreational flying and boating where higher voltage equals better performance.

Frequently Asked Questions
- Can I use this Deans 3S Battery Harness with any RC car, truck, or boat? — The harness will physically connect to any RC equipment with a Deans/T-Plug connector socket, however you must verify that your ESC and all other electronics support the resulting 3S series voltage before connecting. Always check your equipment specifications before use.
- Is this suitable for beginners getting into RC cars UK? — Yes, this harness is suitable for beginners who already understand basic RC battery concepts and have experience with their specific RC models. However, beginners should carefully read all safety information and confirm their equipment compatibility before attempting to use series battery configurations.
- What batteries do I need to use with this harness? — You will need three individual LiPo battery packs that are fitted with Deans (T-Plug) connectors. For best results and safety, all three batteries should have the same voltage rating (typically 3S each), the same capacity (measured in mAh), and similar states of charge.
- How do I ensure correct polarity and safe connection? — The Deans connector design naturally prevents reverse polarity connections, as the connectors only mate in the correct orientation. However, you should always double-check connection order before applying power, and ensure you understand which battery terminal is positive and which is negative.
- Can I use this harness for bench testing? — Yes, the harness is ideal for temporary 3S series arrangements during bench testing scenarios where you need to evaluate your equipment's performance under higher voltage without permanent installation.
- What regular maintenance does this harness require? — Inspect the connectors and wiring regularly for signs of damage, corrosion, or loose connections. Clean the Deans connectors gently if they appear tarnished, and replace the harness immediately if any connector shows damage or poor contact.
- Is this harness suitable for competitive RC racing in the UK? — Yes, many competitive RC racing UK enthusiasts use series battery configurations to achieve higher voltage and improved performance. Always confirm your racing series or club rules allow higher voltage batteries before competing.
