Overview
The EFL Battery Connector Wire: 1S UMX Z-EFLU3052 is a dedicated battery connector solution designed for E-flite's Ultra Micro (UMX) range of RC aircraft and models. This specialised connector wire is engineered to provide reliable power delivery to your small-scale RC planes, helicopters, and other UMX aircraft, ensuring consistent electrical performance and safe battery integration. Whether you're flying micro RC planes in the UK or maintaining your existing collection of ultra-light RC models, this connector is an essential component for keeping your fleet in the air. The E-flite brand is renowned throughout the RC hobby community for producing high-quality connectors that prioritise reliability, durability and precise engineering tailored to their specific model platforms.
As a dedicated connector solution built specifically for 1S (single-cell) battery configurations in UMX applications, this product eliminates compatibility guesswork and delivers the exact fit and electrical characteristics your ultra-micro RC aircraft demands. This is not a universal adapter or generic connector—it is purpose-built for E-flite's UMX ecosystem, which means you get optimised contact design, proper current-carrying capacity and mechanical fit that matches your original equipment. For RC enthusiasts in the UK seeking reliable replacements or spares for their micro-scale RC planes and models, this connector wire offers genuine E-flite engineering at an affordable price point.
Key Features
- 1S UMX-Specific Design — This connector is engineered exclusively for E-flite's Ultra Micro range, ensuring perfect compatibility and reliable mechanical fit with your 1S battery systems without the need for adapters or workarounds.
- Dedicated Battery Connector — Purpose-built as a battery connector wire means the electrical characteristics and physical dimensions are optimised for powering UMX aircraft, delivering safe and consistent energy transfer from your 1S LiPo battery to your model's electronics.
- Genuine E-flite Component — This is an authentic E-flite product, meaning you receive the same quality standards and performance characteristics as your original UMX aircraft, providing confidence in reliability and longevity.
- Replacement and Spare-Friendly — Perfect for RC pilots who need replacement connectors, who have worn existing connections, or who maintain multiple UMX aircraft and need spare battery connection solutions on hand.
- Compact Ultra-Micro Profile — Designed to work within the tight spatial constraints of ultra-micro RC aircraft, the connector maintains the lightweight, minimal-footprint characteristics essential to micro-scale RC flying.
Technical Performance
This battery connector wire is engineered specifically for 1S (single-cell) lithium-polymer battery applications within E-flite's Ultra Micro aircraft range. The 1S configuration delivers 3.7V nominal voltage, which is the standard for small-scale RC planes and micro-sized electric models. The connector construction prioritises low resistance and reliable contact to ensure efficient power transfer with minimal voltage drop, critical for maintaining flight performance in ultra-lightweight RC aircraft where every milliwatt of efficiency counts. The UMX-specific design means the connector dimensions, contact gauge and mechanical fit are optimised for the proprietary connector systems used in E-flite's micro aircraft line, eliminating compatibility issues and providing the precise electrical and mechanical interface your models require. The quality of materials and manufacturing reflects E-flite's reputation in the RC hobby, with attention paid to preventing connector corrosion, maintaining contact pressure over time, and withstanding the vibration and movement inherent to powered RC flight. For UK-based RC flyers maintaining a collection of electric micro planes and helicopters, this connector represents a reliable solution for battery connectivity that matches the engineering standards of your aircraft.

Frequently Asked Questions
- What is the difference between 1S UMX connectors and standard RC battery connectors? — The UMX connector is specifically designed for E-flite's Ultra Micro aircraft platform, featuring dimensions and contact characteristics tailored to 1S battery applications in micro-scale models. Standard connectors like XT60, XT90, Deans or EC3 are designed for larger, higher-power RC vehicles and would be oversized and inappropriate for ultra-light micro aircraft. The UMX connector maintains the compact profile necessary for aircraft where weight and space are critical constraints.
- Is this compatible with all 1S batteries? — This connector is designed specifically for E-flite's UMX ecosystem and is compatible with 1S lithium-polymer batteries used in E-flite Ultra Micro aircraft. Compatibility with non-E-flite or third-party UMX aircraft should be verified before use, as some manufacturers use proprietary connector variations.
- Can I use this connector as a replacement for a damaged battery connection? — Yes, this is an excellent choice for replacement or repair. If your existing UMX battery connector has become worn, damaged or corroded, this genuine E-flite component will restore reliable power connectivity and is recommended over attempting to repair existing connectors.
- What voltage and cell configuration does the 1S designation mean? — 1S indicates a single-cell lithium-polymer battery configuration, delivering 3.7V nominal voltage (4.2V when fully charged). This is the standard battery type for E-flite Ultra Micro aircraft and other small-scale electric RC models, providing the optimal balance of power delivery, weight and flight duration for micro-scale applications.
- What aircraft models use this connector type? — This connector is designed for E-flite's Ultra Micro range, which includes micro RC planes, helicopters and flying wings in the UMX product line. Check your aircraft's documentation or the E-flite website to confirm your specific model's battery connector type before purchasing.
- Is this suitable for beginners? — Yes, if you already own an E-flite UMX aircraft, this is a straightforward replacement connector. For beginners just starting in micro-scale RC flying, purchasing a complete RTR (ready-to-run) UMX aircraft package from E-flite provides all necessary components; this product is ideal once you need spare connectors or replacements.
