Technical Performance
The SPM IC5 Battery Series Harness represents a straightforward but essential component in your RC power delivery chain. The 10 AWG wire gauge has been selected to provide optimal current carrying capacity for the majority of 3S and 4S LiPo battery applications commonly used in modern RC cars UK and beyond. This wire gauge effectively minimises resistance losses across the harness connection, meaning more of your battery's available power reaches your ESC and motor without being wasted as heat. The IC5 connector itself features robust gold-plated contacts that resist corrosion and provide a secure, repeatable connection between battery and vehicle electronics. The 4-inch wire length (100mm) has been engineered to accommodate most conventional RC vehicle layouts without requiring excessive slack or routing challenges. Whether you're installing this harness in a brushless RC truck, an electric RC buggy, or a high-powered RC car, the construction quality and electrical specifications ensure reliable performance during demanding high-drain applications. The connector design includes safety features that prevent accidental disconnection under the vibrations and impacts inherent to RC motorsport, giving you peace of mind whether you're racing competitively or bashing recreationally.

Frequently Asked Questions
- Is the IC5 connector compatible with my RC vehicle? — The IC5 connector has become an industry standard across numerous RC brands and platforms. If your RC car, truck, buggy, or crawler features an IC5 connector socket on the battery leads or main power distribution board, this harness will work with your vehicle. Many competitive and performance-oriented RC models from leading manufacturers now use IC5 connectors as standard, making this an excellent universal choice for RC enthusiasts with multiple vehicles.
- What is the difference between this harness and other battery connectors available? — The IC5 connector offers improved contact surface area and lower resistance compared to older T-connector or 4mm banana plug standards, meaning better current flow and reduced voltage drop during high-demand applications. The gold-plated contacts resist oxidation better than bare copper alternatives, ensuring consistent performance over time. The 10 AWG wire gauge in this harness is thicker and more robust than smaller gauge options, making it suitable for high-performance applications that draw significant current from your battery pack.
- What battery types and capacities can I use with this harness? — The 10 AWG wire gauge and IC5 connector are designed to safely handle standard lithium polymer (LiPo) battery packs used in modern RC vehicles, including 3S and 4S configurations that are commonplace in today's ready to run RC and custom-built models. The harness is engineered for batteries ranging from moderate capacity packs through to high-capacity extended runtime batteries used in endurance racing and long-session bashing.
- Is this suitable for beginners to RC hobbies? — Whilst this harness is simple to connect and disconnect, it is a replacement or upgrade component rather than part of a ready to run package. Beginners should ensure they understand the basics of RC vehicle setup and battery management before installing custom harnesses. However, if you already own an RC vehicle with an IC5 connector and need a replacement harness or are upgrading your current setup, this product is straightforward to install and use with proper guidance.
- What safety considerations should I be aware of? — Always ensure the IC5 connectors are fully seated and locked before operating your RC vehicle. Check that the gold-plated contacts are clean and free from debris before each use. The 10 AWG wires carry high current and can become hot during extended use, so never touch the connectors during or immediately after operation. Store the harness safely away from moisture and extreme temperatures, and inspect the wires regularly for signs of damage or wear.
