Measuring approximately 30cm in length, this charge lead strikes the perfect balance between providing adequate reach for convenient connections whilst minimising excess cable clutter in your RC charging setup. The flexible silicone wire construction ensures the lead stays manageable and easy to route, even in tight spaces around your charger or battery storage area.

Key Features

• EC3 to 4mm Gold Connector Design — The charge lead features EC3 male connectors on one end and 4mm gold connectors on the other, providing direct compatibility with E-Flite and ParkZone LiPo batteries whilst connecting to any standard RC charger that accepts 4mm banana plugs, eliminating the need for additional adapters.
• Gold-Plated Brass Contacts — The contacts are manufactured from gold-plated brass, which guarantees low electrical resistance and minimal voltage drop during charging cycles, ensuring consistent and efficient power delivery that reduces charging times and protects your battery's health.
• Premium Silicone Wire Construction — Made with high-quality 16AWG (1.5mm) multi-strand soft silicone wire, this charge lead offers exceptional flexibility and durability, allowing it to withstand frequent connections and disconnections without developing cracks or becoming brittle over time.
• Durable Nylon Insulation — The wire insulation is reinforced with nylon (PA) material, providing excellent resistance to wear, heat damage, and environmental stress, making this lead suitable for demanding RC charging environments and frequent use.
• Optimal 30cm Length — At approximately 300mm long, this charge lead provides the ideal balance between reach and cable management, allowing you to position your battery conveniently whilst keeping your charging station neat and organised.
• Wide Charger Compatibility — This lead works with the majority of RC battery chargers that accept 4mm banana plug connectors, making it a versatile addition to any RC charging setup, whether you're using field chargers, fast chargers, or multi-chemistry chargers.
• Secure and Stable Connections — The EC3 connectors provide a tight, secure fit to your E-Flite and ParkZone batteries, whilst the 4mm gold connectors ensure stable contact with your charger, reducing the risk of loose connections that could interrupt charging cycles.
• User-Friendly Design — The soft, flexible silicone wire is easy to handle and manoeuvre, even in tight spaces, enabling quick and straightforward connections without requiring any special tools or technical knowledge.

Technical Performance

The Overlander EC3 Charge Lead represents a significant step up from using generic adapter leads or improvised charging solutions. The combination of 16AWG (1.5mm) multi-strand silicone wire and gold-plated brass contacts ensures minimal electrical resistance throughout the charging circuit, which translates to faster charging times and more consistent current delivery to your EC3-equipped LiPo batteries. The wire gauge of 16AWG is specifically chosen to handle the current requirements of typical RC battery chargers whilst maintaining flexibility and ease of use. The nylon insulation provides excellent protection against accidental damage, cuts, and exposure to moisture or dirt commonly found in RC charging environments. Factory-soldered joints and reinforced shrink-wrapping ensure the connections remain secure and reliable even after hundreds of charge cycles. The flexible silicone material resists cracking and hardening that can occur with cheaper PVC insulation, particularly in cold weather conditions or after extended storage, making this lead suitable for RC enthusiasts across the UK regardless of local climate conditions. Whether you're charging high-capacity LiPo batteries for extended RC flights, rapid-fire charging sessions during RC racing events, or maintaining a collection of batteries for various RC vehicles including RC cars, RC planes, and RC helicopters, this charge lead delivers the performance and reliability you need for safe, efficient charging every single time.

Frequently Asked Questions

• Is the Overlander EC3 Charge Lead suitable for E-Flite and ParkZone RC batteries? — Yes, absolutely. This charge lead is specifically designed with EC3 connectors that match the standard connector found on E-Flite and ParkZone LiPo batteries. The EC3 connector provides a secure fit and reliable connection for safe, efficient charging without requiring any adapters or modifications.
• What chargers is this compatible with? — This charge lead works with the majority of RC battery chargers that accept standard 4mm banana plug connectors. This includes field chargers, fast chargers, multi-chemistry chargers, and most hobby-grade RC battery charging units available in the UK.
• Why should I use a dedicated charge lead instead of adapters? — Using a dedicated charge lead like the Overlander 722 eliminates multiple connection points that can introduce electrical resistance, heat build-up, and potential failure points. Adapters stack additional connections into your charging circuit, which can slow charging speeds and compromise battery safety. A purpose-built charge lead provides a direct, low-resistance path from your charger to your battery, ensuring optimal charging performance and protecting your investment in quality LiPo batteries.
• How long is the charge lead? — The Overlander EC3 Charge Lead measures approximately 30cm (300mm) in length, which provides adequate reach for convenient connections whilst minimising excess cable clutter in your charging setup.
• What wire gauge is used? — This charge lead is constructed with 16AWG (1.5mm) multi-strand soft silicone wire, which provides the optimal balance between flexibility, durability, and electrical conductivity for typical RC battery charging applications.
• Are the contacts gold-plated? — Yes, the 4mm connectors feature gold-plated brass contacts, which ensure low electrical resistance, minimal voltage drop, and reliable conductivity throughout the charging cycle, resulting in faster charging times and better overall performance.
• Can beginners use this charge lead? — Definitely. The Overlander 722 is incredibly straightforward to use—simply plug the EC3 end into your battery and the 4mm connectors into your charger. There are no special tools, soldering, or technical knowledge required, making this an ideal charge lead for RC hobbyists at any skill level.
• Is this lead suitable for LiPo batteries? — Yes, this charge lead is designed to work with LiPo batteries equipped with EC3 connectors, which is the standard connector type for E-Flite and ParkZone LiPo battery packs used across RC planes, helicopters, drones, and other RC models.
• What makes silicone wire better than PVC? — Silicone wire is significantly more flexible, more resistant to cracking and hardening over time, and maintains its properties across a wider range of temperatures. This makes silicone-insulated charge leads more durable and longer-lasting, particularly in the variable UK climate where temperatures can fluctuate significantly between seasons.
