Overview

The Spektrum SPM 3 inch Parallel Y-Harness with IC3 Device connector (model O-SPMX-1113) is an essential charging and power distribution accessory for RC enthusiasts across the UK. Whether you're running a high-performance brushless RC car, an electric buggy, or any other RC model powered by LiPo batteries, this Y-harness provides a convenient and safe way to charge two batteries simultaneously or distribute power to multiple devices. Designed by Spektrum, the recognised leader in spread spectrum technology, this harness combines practical engineering with the reliability that serious RC hobbyists demand. If you're looking to expand your charging setup, reduce downtime between runs, or simply need a backup connector for your RC collection, the SPM 3 inch Parallel Y-Harness is an indispensable addition to your RC toolkit.

The IC3 Device connector has become the industry standard for many modern RC vehicles and battery systems, making this parallel Y-harness compatible with a wide range of RC products. Whether you're a casual weekend basher or a competitive racer, having multiple charging options means more time behind the transmitter and less time waiting for batteries to charge. The 12 AWG gauge wire provides robust power transmission with minimal voltage drop, ensuring efficient charging and power delivery to your RC equipment. Available from RC Model Shop, this genuine Spektrum component is the perfect choice for UK RC hobbyists who demand authentic parts and proven performance.

This Y-harness is particularly valuable for those running multiple RC cars UK enthusiasts often maintain – having the ability to charge two batteries at once dramatically improves your hobby experience and lets you maximise your track time or bashing sessions. The parallel configuration means both battery ports receive equal voltage and current, making it ideal for charging matching pairs of batteries or distributing power to different systems simultaneously.

Key Features

• IC3 Device Connector — This industry-standard connector ensures broad compatibility with modern RC batteries, chargers, and electrical systems, meaning you can use this harness with most contemporary RC vehicles and battery packs without needing additional adapters or modifications.
• 12 AWG Gauge Wire — The 12 AWG copper wire gauge provides excellent conductivity and current-carrying capacity, which minimises voltage drop during charging and power delivery, allowing your batteries to charge faster and your RC vehicle to perform at its peak potential.
• 3 inch Parallel Configuration — The parallel Y-harness splits a single power input into two separate branches of equal length and specifications, enabling simultaneous charging of two batteries or powering two separate systems from a single source without compromising performance on either branch.
• Genuine Spektrum Quality — As an official Spektrum component, this Y-harness is manufactured to exacting standards with quality connectors and insulation that meet professional RC racing and hobby requirements, ensuring long-term reliability and safe operation.
• Compact and Practical Design — The 3 inch harness length provides convenient reach between your charger or power source and your battery connections without excessive coiling or tangled wires, keeping your charging station organised and safe.

Technical Performance

The Spektrum SPM 3 inch Parallel Y-Harness represents thoughtful engineering for serious RC hobbyists. Built with 12 AWG gauge copper wire, this harness is designed to handle the high current demands of modern LiPo battery charging and RC vehicle power systems without overheating or losing efficiency. The IC3 Device connector interface has become the standard across the RC industry, adopted by manufacturers of ready to run RC cars, brushless RC buggies, and performance-oriented electric RC vehicles. The parallel configuration ensures that both branches of the Y-harness maintain identical voltage characteristics, which is critical when charging two batteries in sequence or distributing power to dual-system vehicles. The 3 inch length is engineered to provide comfortable reach during setup and teardown at the track or field without creating bulk in your charging station. Whether you're charging premium LiPo batteries for your 1/10 brushless RC car or managing power for dual-battery RC rock crawlers, this harness maintains the signal integrity and power delivery reliability that Spektrum's reputation demands. The robust construction and sealed connectors protect against corrosion and accidental short circuits, features that every serious RC enthusiast UK-based or otherwise will appreciate after investing in quality RC equipment.

Frequently Asked Questions

• What is an IC3 Device connector and will it work with my RC battery? — The IC3 Device connector is an industry-standard connector found on many modern RC batteries, chargers, and power distribution systems. If your RC vehicle or battery pack features an IC3 connector, this harness will work perfectly. Check your battery specifications or look at the connector on your battery pack – if it matches the IC3 standard, this Y-harness is fully compatible.
• Why would I need a parallel Y-harness for my RC car? — A parallel Y-harness is invaluable if you own multiple RC vehicles or battery packs. It allows you to charge two batteries simultaneously from a single charger outlet, dramatically reducing downtime and allowing you to keep multiple RC cars UK racing or bashing. It's also useful for distributing power to dual-battery systems in larger RC models.
• What does 12 AWG wire gauge mean and why does it matter? — The 12 AWG (American Wire Gauge) specification refers to the diameter and current-carrying capacity of the copper wire inside the harness. A larger gauge number means thinner wire; 12 AWG is relatively thick and can safely handle high currents, which is essential for charging high-capacity LiPo batteries without voltage loss or overheating.
• Is this harness suitable for all Spektrum batteries and chargers? — This harness features the IC3 Device connector, which is compatible with Spektrum batteries, chargers, and vehicles that use the IC3 standard. Always check that your specific battery pack and charger both feature IC3 connectors before purchasing to ensure full compatibility with your RC equipment.
• Can I use this to charge two different battery capacities at the same time? — Yes, the parallel configuration allows you to charge two batteries simultaneously, and they do not need to be identical. However, charging two batteries from a single charger source means the available current is divided between them, so charging times may be longer than charging individually – check your charger specifications for dual-charging support.
• How durable is this harness for regular use? — The SPM 3 inch Parallel Y-Harness is built by Spektrum with quality connectors, solid wire gauge, and professional-grade insulation, making it suitable for regular, frequent use in competitive and casual RC environments. With proper care and storage, it will provide years of reliable service.
