Overlander XT90 Female to EC5 Male Adaptor Lead RC Battery Connector 3283

Overview

The Overlander XT90 Female to EC5 Male Adaptor Lead – 3283 is a premium-quality conversion lead designed to provide seamless compatibility between XT90-equipped batteries and EC5-based electronic speed controllers, chargers, and devices. This adapter is an essential accessory for RC enthusiasts in the UK who run mixed connector systems across their RC car, aircraft, drone, helicopter, or boat fleet. Whether you're an experienced RC racer, a weekend basher, or a beginner just getting started with your first brushless setup, this adaptor eliminates the need for permanent modifications or risky soldering, offering a simple plug-and-play solution that saves time and protects your valuable equipment.

Built by Overlander, a trusted name in RC batteries and accessories, the 3283 adaptor features robust construction with heat-resistant materials and gold-plated connectors that ensure efficient power transfer and reliable connectivity under demanding conditions. The adaptor's compact 50mm length makes it ideal for tight battery compartments while providing ample reach for secure connections. With low-resistance connectors and flexible silicone wiring, this lead maintains consistent power delivery whether you're charging your XT90 LiPo batteries, connecting them to an EC5-equipped ESC during high-speed runs, or switching between different charger brands without rewiring.

For RC hobbyists managing multiple models with different connector types—a common scenario in competitive RC racing, freestyle flying, or casual bashing—the 3283 adaptor is an indispensable part of any RC toolkit. It allows you to standardise your power infrastructure, maximise equipment compatibility, and protect against the expensive damage that can result from improper connector modifications.

Key Features

• EC5 Male to XT90 Female Conversion — This adaptor connects XT90 Female battery connectors to EC5 Male ESC or charger connectors, enabling you to use your XT90-equipped LiPo batteries with any EC5-compatible device without modification, cutting, or soldering.
• Gold-Plated Brass Connectors — The contacts are finished in hard gold plating over high-conductivity brass, which resists corrosion, reduces contact resistance, and ensures reliable electrical connection even after repeated plug-unplug cycles in damp UK conditions.
• 12AWG Multi-Strand Silicone Wire (4mm) — The lead is constructed from professional-grade 4mm multi-strand silicone wire rated at 12AWG gauge, which provides excellent flexibility for positioning in tight spaces whilst maintaining the structural integrity needed for high-current applications in brushless RC setups.
• Heat-Resistant Silicone Insulation — The soft silicone insulation surrounding the wire offers superior heat resistance compared to standard plastic-jacketed leads, protecting the conductor from damage during continuous high-current operation in demanding brushless motor and ESC applications.
• Nylon Housing with Strain Relief — The connector housing is injection-moulded from tough nylon (polyamide) material that resists vibration, environmental stress, and thermal cycling, ensuring the connections remain snug and secure after thousands of connect-disconnect cycles.
• Compact 50mm Length — At approximately 50mm, the lead is long enough to reach from a battery compartment to an external ESC or charger, yet short enough to avoid excessive cable clutter in compact RC car chassis, aircraft fuselages, or drone frames.
• Low-Resistance Design for High Current — The combination of large-gauge wire, multi-strand construction, and gold-plated connectors minimises voltage drop under heavy current loads, which is critical for maintaining power delivery during acceleration, takeoff, or high-speed RC car runs where every millivolt matters for performance.
• Versatile Compatibility Across RC Disciplines — This adaptor works with LiPo, LiPo, and LiPo batteries across RC cars, RC aircraft, RC drones, RC helicopters, RC boats, and RC crawlers, making it a universal solution for hobbyists who own multiple models with mixed connector ecosystems.

Technical Performance

The Overlander 3283 adaptor is engineered to handle the demanding electrical requirements of modern brushless RC systems. With a wire gauge of 12AWG (4mm diameter), the lead can safely manage the high current draws typical of competitive 1/10-scale RC cars, 1/8-scale buggies, and 3S/4S LiPo-powered racing drones. The multi-strand silicone construction provides superior flexibility compared to solid-core wire, allowing the adaptor to bend and route through tight spaces without kinking or creating stress points that could degrade the conductor over time. The gold-plated brass connectors maintain a contact resistance well below 10 milliohms when properly seated, which translates to minimal voltage loss even at currents exceeding 100 amps during peak acceleration or motor startup transients. The nylon insulator material provides excellent environmental sealing, protecting the gold plating from oxidation and salt-air corrosion, particularly important for RC boat enthusiasts operating in coastal UK waters. The heat-resistant silicone jacket withstands continuous operation at temperatures up to 120°C without degradation, making this adaptor suitable for extended racing sessions, high-discharge LiPo batteries, and ESCs with minimal thermal design margins.

What's in the Box

• 1x Overlander XT90 Female to EC5 Male Adaptor Lead (3283)

Frequently Asked Questions

• Can I use this XT90 to EC5 adaptor with any 3S or 4S LiPo battery? — Yes, this adaptor works with any XT90 Female connector LiPo battery regardless of capacity (mAh) or discharge rating (C-rating), provided the battery pack has an XT90 Male connector. The adaptor simply converts the connector type without affecting battery voltage or chemistry compatibility.
• Is the Overlander 3283 suitable for high-current brushless racing applications? — Absolutely. The 12AWG (4mm) silicone wire and gold-plated connectors are designed specifically for high-current applications found in competitive 1/10-scale RC cars and 1/8-scale RC buggies running brushless ESCs drawing 100+ amps. The low-resistance construction ensures minimal voltage drop during acceleration peaks.
• Will this adaptor work with EC5 chargers that use standard banana plugs? — No. This adaptor provides an XT90 Female to EC5 Male connector conversion. If your charger has EC5 Female connectors, it will accept this adaptor's EC5 Male connector. For chargers with 4mm banana plugs, you would need a separate EC5 to banana plug charge lead.
• What is the difference between this XT90 to EC5 adaptor and a XT60 to Deans adaptor? — The key differences are the connector types and current ratings. XT90 connectors are rated for higher continuous currents (up to 90 amps) than XT60 connectors (up to 60 amps), and EC5 connectors are rated higher than Deans T-plugs. This 3283 adaptor is designed for larger, higher-power systems, whilst XT60-to-Deans adaptors suit smaller or intermediate-power RC setups.
• Is this adaptor suitable for beginners setting up their first brushless RC car in the UK? — Yes, it's an excellent choice for beginners. Rather than learning to solder connectors or risk damaging a new ESC and battery, this plug-and-play adaptor allows you to safely experiment with different battery and charger combinations. It's a safe, tool-free solution that builds confidence.
• Can I use multiple adaptors in series? — It's not recommended. Chaining multiple adaptors adds extra connection points, each introducing a small amount of resistance and potential failure points. If you need different connector types, it's better to use a single, direct adaptor like the 3283.
• How durable is the nylon housing in the Overlander adaptor? — The nylon (polyamide) housing is injection-moulded to be impact-resistant and flex-tolerant, handling thousands of connection cycles without cracking or loosening. It resists UV degradation, moisture ingress, and thermal cycling, making it suitable for outdoor RC racing and flying in variable UK weather conditions.
