Key Features
- IC3 Connector Compatibility — The harness utilises the IC3 connector standard, which is one of the most widely adopted connector types in the RC hobby, ensuring broad compatibility with Spektrum batteries, chargers, and other IC3-equipped devices in your RC arsenal.
- 13 AWG Gauge Wiring — The premium 13 AWG (American Wire Gauge) wiring delivers substantial current-carrying capacity, which is critical for maintaining stable power delivery to your RC batteries and minimising voltage drop during charging cycles, particularly important for high-performance RC setups.
- 6-Inch Length — The 150mm (6-inch) length provides an ideal balance between reach and manoeuvrability, allowing you to position batteries and chargers flexibly without excessive wire length whilst maintaining enough coverage for practical installation in various RC charging stations and vehicle configurations.
- Series Harness Configuration — Designed for series battery connections, this harness is essential for users who need to connect multiple batteries in series configuration or require an intermediate connection point in their battery management system.
- Quality Construction — Built to Spektrum's exacting standards, the harness features reliable soldering and insulation, providing durability through repeated connect-disconnect cycles and extended storage periods, giving you confidence in its longevity.
Technical Performance
The Spektrum IC3 Battery Series Harness represents thoughtful engineering applied to an essential RC component. The use of 13 AWG gauge copper wiring is particularly significant, as this thickness strikes an optimal balance between current capacity and practical flexibility—robust enough to handle the demanding power delivery requirements of modern LiPo batteries and brushless RC systems, yet flexible enough to route through tight spaces in battery boxes, charging stations, and vehicle installations. The 6-inch length is carefully considered to accommodate both compact setups and those requiring slightly more reach between connection points. The IC3 connector itself is engineered for durability, featuring gold-plated contacts that resist oxidation and corrosion over time, maintaining reliable electrical connections through dozens of charge cycles. For users operating multiple RC vehicles—whether running 1/10 scale brushless RC buggies, larger RC trucks, or other battery-powered RC equipment—having quality harnesses on hand ensures you're never left without a working solution. The construction methodology reflects Spektrum's commitment to quality, with professional-grade soldering and insulation throughout, minimising the risk of intermittent connections or failure modes that could damage batteries or chargers. This is the kind of component that often goes unnoticed when working perfectly, but becomes invaluable when you need a reliable backup or replacement harness.

Frequently Asked Questions
- What is an IC3 connector and why does it matter for my RC setup? — The IC3 connector is a widely-used standardised connector in the RC hobby, particularly popular with Spektrum batteries, chargers, and power systems. It features a compact design with robust gold-plated contacts that provide reliable electrical connection. If you're using Spektrum charging accessories or IC3-compatible batteries, having quality IC3 harnesses ensures you can safely and reliably connect your power systems without risk of poor connections or compatibility issues.
- What is 13 AWG wiring and why is it important? — AWG (American Wire Gauge) refers to the thickness of electrical wire, with lower numbers indicating thicker wire. 13 AWG is considered heavy-duty wiring suitable for high-current applications, making it ideal for battery harnesses where substantial current flows during charging. This gauge minimises voltage drop and reduces heat generation, both critical factors for battery safety and charger efficiency in RC applications.
- Is this suitable for beginners? — Yes, the IC3 Battery Series Harness is suitable for RC enthusiasts of all experience levels. If you're new to the RC hobby and using Spektrum or IC3-compatible equipment, this harness is a straightforward connector that works reliably without requiring special installation knowledge. It's simply a matter of connecting IC3 male to female connectors securely.
- What length should my battery harness be? — The 6-inch (150mm) length is a practical middle-ground size that works well for most RC setups. It's long enough to reach between a battery box and charger without excessive wire, yet short enough to avoid tangled cables in your RC workspace. If you find you need longer or shorter harnesses, Spektrum offers the IC3 Series Harness in various lengths to suit different configurations.
- Can I use this harness with non-Spektrum batteries? — The IC3 connector is a standardised connector used by multiple manufacturers in the RC industry. If your battery, charger, or other RC equipment uses IC3 connectors, this Spektrum harness will be compatible. However, if your equipment uses different connectors such as XT60, Deans, or other proprietary types, you would need a harness with matching connectors instead.
- How do I know if I need a replacement harness? — Signs that you might need a replacement IC3 harness include loose or intermittent connections, visible damage to the connector or wiring insulation, corrosion on the connector contacts, or simply wanting a backup harness for convenience when managing multiple RC vehicles. Having a spare harness on hand prevents unnecessary downtime during RC sessions.
