Key Features
- Parallel Connection Design — This adaptor harness links two battery packs in parallel, which means both packs operate at the same voltage level, effectively doubling your total battery capacity. This is critical for extended run times because you can stay out on the track or field for significantly longer sessions without having to stop and swap batteries.
- Voltage Preservation — When batteries are connected in parallel, the system voltage remains unchanged, which is essential for maintaining compatibility with your existing RC model's electronics, ESC (Electronic Speed Controller) and motor setup. You won't need to recalibrate or adjust anything; the system simply sees a larger capacity battery.
- Extended Run Time — By doubling your battery capacity whilst keeping voltage constant, you can enjoy roughly double the run time between charging sessions. For competitive racers or weekend bashers, this means fewer interruptions and more time enjoying your RC model.
- Practical Adaptor Construction — The harness is engineered as a simple, tidy wiring solution that connects cleanly to your existing battery connectors. No soldering or complex modifications are required; it's a plug-and-play solution that works with standard RC battery connectors.
- General RC Application Compatibility — Designed for broad compatibility across RC applications, this adaptor works with a wide range of RC models, from electric cars and trucks to buggies and crawlers. If your model accepts standard battery connectors, this harness will integrate seamlessly.
- Etronix Quality Assurance — Manufactured by Etronix, this product benefits from the company's reputation for producing reliable, durable RC accessories that stand up to regular use in competitive and recreational environments.
Technical Performance
The Etronix Battery Harness For 2 Packs In Parallel Adaptor is engineered with practicality and reliability at its core. The design focuses on safe, efficient parallel connection of two battery packs without introducing unnecessary complexity or potential failure points. The harness uses quality wiring and connectors that are designed to handle the current demands of typical RC applications. When two packs are connected in parallel, each pack shares the current load equally, which actually reduces stress on individual battery cells and can extend overall battery life compared to running a single pack continuously. The adaptor maintains consistent electrical connectivity and is built to withstand the demands of regular RC use, whether you're running high-speed RC cars on tarmac, bashing through off-road terrain, or engaging in competitive racing. The straightforward construction means there are no weak points in the design, and the adaptor integrates seamlessly with existing RC battery systems and connectors that are standard across the hobby.

Frequently Asked Questions
- What is the difference between parallel and series battery connections for RC models? — When batteries are connected in parallel, the voltage stays the same but the capacity (and therefore run time) doubles. When connected in series, the voltage doubles but capacity remains the same. This adaptor creates a parallel connection, making it ideal if you want longer run times without altering your system voltage or requiring ESC recalibration.
- Can I use this adaptor with any RC model? — The ET0705 is designed for general RC applications and works with any model that uses standard battery connectors. As long as both battery packs have compatible connectors, you can use this harness. However, always check your model's documentation to ensure it's designed to accept higher capacity batteries, as some models may have size or weight restrictions in the battery bay.
- Do I need to do anything special to balance charge two packs in parallel? — When packs are connected in parallel via this adaptor, they will automatically balance each other during charging. However, it's still good practice to monitor your packs during first use to ensure they're charging evenly. Some modern chargers have parallel charging capabilities that work seamlessly with this type of setup.
- Is this suitable for beginners? — Yes, absolutely. The ET0705 is extremely beginner-friendly because it requires no soldering, no modifications to your RC model, and no technical knowledge beyond plugging in connectors. It's simply a plug-and-play solution that even newcomers to RC can use with complete confidence.
- What battery packs work with this adaptor? — This adaptor works with any two battery packs that have compatible connectors. The most common battery types in RC are LiPo (Lithium Polymer) and NiMH (Nickel Metal Hydride), and the ET0705 works with both, provided they're the same voltage and capacity for balanced operation.
- Will using this adaptor affect my RC car's performance? — No, because the voltage remains unchanged, your motor speed and ESC performance stay exactly the same. The only difference you'll notice is that your RC car will run for approximately twice as long before needing a battery swap, which is purely a positive benefit.
- What makes Etronix adaptors reliable for RC use? — Etronix is a trusted manufacturer in the RC community, known for producing quality accessories that handle the demands of regular use. This adaptor uses proper connectors and wiring to ensure safe, reliable operation across a wide range of RC applications, from casual backyard running to competitive racing.
