Key Features

• IC3 Battery Connector Compatibility — This extension is specifically designed to work with IC3-type battery connectors, which are widely used across modern Spektrum RC products and many other quality RC vehicles. IC3 connectors are recognised for their reliability, secure fit, and low resistance characteristics, making them the preferred choice for serious RC applications where power integrity is paramount.
• IC3 Device Compatibility — Beyond battery connections, this harness supports IC3-equipped devices, allowing you to extend the reach and flexibility of your charging and power distribution setup. This versatility means you can configure your RC station precisely as you need it, whether you're charging multiple batteries simultaneously or connecting auxiliary power systems.
• 3-Inch Extension Length — The purposeful 3-inch length provides meaningful extension capability without excessive cable length that could create clutter or management issues in your RC workspace. This compact yet practical length makes it ideal for tight installations, custom battery trays, and scenarios where standard connector reach falls just short of your requirements.
• Power Tap Functionality — The integrated power tap allows simultaneous battery charging and device operation, a critical feature for those who need to maintain power to onboard electronics, telemetry systems, or other peripherals whilst charging. This eliminates the frustration of disconnecting and reconnecting multiple times during your RC session.
• Spektrum Quality Engineering — As a genuine Spektrum product, this extension harness benefits from the same rigorous quality control and performance standards applied to all Spektrum components. You can be confident that this connector will deliver reliable, safe, and consistent performance throughout its operational life.
• Professional-Grade Reliability — Whether you're operating competition-level RC cars, off-road buggies, or casual bashers, this extension maintains the electrical integrity your RC equipment demands. The secure IC3 connection type minimises voltage drop and ensures optimal power delivery to all your RC systems.

Technical Performance

The SPM 3 inch Extension: IC3 Battery/IC3 Device with Power Tap represents Spektrum's engineering excellence in power distribution and connectivity solutions for the RC hobby. Built to exacting standards, this harness ensures that whether you're using high-performance brushless RC motors with demanding power requirements or more modest setups, your electrical connections remain secure and efficient. The IC3 connector system featured in this extension uses gold-plated contact points to minimise resistance and maximise conductivity, crucial factors when working with high-discharge-rate LiPo batteries commonly used in modern RC vehicles. The 3-inch length has been carefully engineered to provide practical extension capability whilst maintaining manageable cable routing in typical RC pit setups. The power tap functionality enables users to charge batteries whilst simultaneously powering receiver units, telemetry modules, or other onboard electronics, a feature increasingly important in modern RC competition where real-time data monitoring enhances performance. The harness construction utilises high-quality materials throughout, with properly insulated wiring and secure connector housings that protect against accidental shorts or connection failures. Whether you're operating a 1/10-scale RC buggy, a rock crawler, a stadium truck, or any other RC platform utilising Spektrum technology, this extension delivers the reliability and performance expected from a component bearing the Spektrum name and backed by their reputation as the leader in spread spectrum technology for RC applications.

Frequently Asked Questions

• What is the IC3 connector and why does it matter for my RC setup? — The IC3 is a high-quality battery and device connector system developed and widely adopted by Spektrum and many other RC manufacturers. IC3 connectors are specifically designed for reliable power delivery in RC applications, featuring secure fitment, low electrical resistance, and consistent performance across thousands of connect-disconnect cycles. If your RC batteries, charger, or receiver utilise IC3 connectors, this extension harness ensures you can safely extend your connections without compromising electrical integrity.
• Can I use this extension with different RC battery types? — The SPM 3 inch Extension is designed to work with any IC3-compatible battery, which encompasses many modern LiPo, LiFe, and NiMH battery packs commonly used in RC vehicles throughout the UK. Always verify that your specific battery or device features an IC3 connector before purchasing, as connector type varies across different RC manufacturers and product lines.
• What does the power tap do and why would I need it? — The integrated power tap allows you to charge your battery whilst simultaneously powering onboard electronics such as receiver units, telemetry modules, or other devices. This is particularly valuable during maintenance, testing, or competition preparation, as it eliminates the need to disconnect and reconnect power sources repeatedly throughout your RC session. This feature also supports simultaneous charging of multiple batteries when used with compatible charging systems.
• Is this extension suitable for high-powered brushless RC cars and trucks? — Yes, the IC3 connector system is specifically engineered to handle the high-discharge rates typical of modern brushless RC vehicles. Whether you're running a competitive 1/10-scale stadium truck, an off-road buggy, or any other brushless RC model, the IC3 connection provides the electrical reliability and low-resistance characteristics required for optimal performance.
• How does the 3-inch length compare to standard connector cables? — The 3-inch extension length provides a meaningful extension capability beyond what direct battery-to-device connections offer, whilst remaining compact enough for practical RC pit setup. This length is particularly useful when your battery charger connector falls slightly short of your device connection point, or when you need to position batteries in custom trays or holders at slight distance from your RC vehicle's onboard electronics.
• Will this work with my Spektrum receiver and other RC equipment? — This extension is designed specifically for IC3-type connectors, so it will work with any Spektrum equipment, batteries, or third-party RC products that utilise the IC3 standard. However, always verify the connector type on your specific equipment before purchasing, as some RC devices use alternative connector systems such as XT60, Deans, or other proprietary designs.
