Key Features

• 4S Lithium Polymer Chemistry — The four-cell series configuration delivers a nominal voltage of 14.8V (16.8V fully charged), which is the industry standard for high-performance RC applications and provides excellent power delivery across a wide range of brushless motors and electronic speed controllers without requiring voltage conversion.
• 3250mAh Capacity — This mid-range capacity offers a practical balance between weight and runtime, delivering sufficient power for extended running sessions whilst keeping the overall battery mass manageable for smaller to medium-sized RC vehicles and preventing excessive weight penalty in your model bay.
• 50C Continuous Discharge Rating — The 50C rating means this battery can safely deliver 162.5 amps of continuous current (3250mAh × 50), making it suitable for high-performance brushless motors that demand significant power, including competition-grade systems and aggressive driving styles on RC buggies, trucks, and racing vehicles.
• EC3 Connector — The EC3 connector is one of the most widely adopted standards in the RC hobby, ensuring seamless compatibility with most modern brushless ESCs and chargers available to RC enthusiasts in the UK market, eliminating the need for adapter cables or connector modifications.
• Compact Dimensions — At just 135mm long, 42mm wide, and 28mm tall, this battery fits into tight spaces that larger capacity packs cannot access, making it ideal for compact RC models where space constraints would otherwise limit your power options or force you to use lower-capacity alternatives.
• Soft Case Protection — The included soft case provides essential protection for your battery during transport and storage, preventing physical damage, moisture ingress, and accidental short circuits whilst remaining lightweight and space-efficient compared to rigid hard cases.
• Reliable Radient Brand Quality — Radient batteries are recognised throughout the RC hobby community for consistent performance and reliability, giving you confidence that your investment in this battery will deliver dependable power delivery for months of enjoyable RC driving.

Technical Performance

The Radient LiPo 4S 3250mAh 14.8V 50C EC3 battery represents solid engineering and practical design for serious RC hobbyists. The 4S (four-cell) lithium polymer construction generates 14.8V nominal voltage, which climbs to 16.8V when fully charged—a specification that aligns perfectly with modern brushless motor systems and electronic speed controllers used throughout competitive and recreational RC racing in the UK. The 50C continuous discharge rating is particularly significant for performance-focused drivers, providing sufficient current capacity to power high-KV brushless motors without voltage sag during acceleration or high-demand manoeuvres. The 3250mAh capacity sits in the sweet spot for weight-conscious builders who need extended runtime without the mass penalty of larger 5000mAh or 6000mAh packs. The EC3 connector, whilst increasingly supplemented by XT90 and XT60 connectors in the market, remains a well-established standard that you'll find on most mid-range brushless ESCs and many chargers throughout the UK. Dimensionally, at 135 × 42 × 28mm, this battery is genuinely compact—designed for builders working with tight model bays where aftermarket batteries must fit within specific spaces. The soft case protection ensures your battery remains safe during transport and storage, preventing the physical damage and moisture exposure that can degrade LiPo performance over time. Whether you're running a 1/10 scale RC buggy, a short-course truck, or a stadium truck platform, this battery offers the voltage and current delivery needed for serious performance without requiring exotic charging infrastructure or specialised connectors.

Frequently Asked Questions

• What vehicles is the Radient 4S 3250mAh battery compatible with? — This battery is compatible with RC models that accept an EC3-equipped 4S LiPo battery and can physically accommodate a pack measuring approximately 135 × 42 × 28mm. Before purchasing, verify that your vehicle's battery bay has sufficient space for these dimensions, as this is a compact pack designed for space-constrained applications. Check your model's documentation to confirm EC3 connector compatibility and 4S voltage compatibility with your ESC.
• Is this battery suitable for beginners in RC hobbies? — The Radient 4S 3250mAh is best suited to RC hobbyists with some experience in lithium polymer battery handling, storage, and charging. Whilst the battery itself is reliable and user-friendly, 4S LiPo packs require proper charging equipment, balanced charge protocols, and safe storage practices. If you're new to RC hobbies in the UK, we recommend discussing battery safety and charging procedures with RC Model Shop staff before your first use.
• What is the weight of this Radient battery? — The Radient LiPo 4S 3250mAh 14.8V 50C EC3 battery weighs approximately 370 grams, which is a reasonable mass for a pack of this capacity and makes it suitable for mid-size RC vehicles without creating excessive weight penalty that would compromise handling or acceleration.
• Will this battery be too heavy for smaller RC models? — At approximately 370 grams, this battery may be too heavy and too large for small-scale RC models such as the E-Flite Ultimate 3D biplane or other compact aircraft and micro-scale vehicles. We recommend checking your model's recommended battery weight range and physical battery bay dimensions before purchasing. Contact RC Model Shop for advice if you're uncertain about compatibility.
• What charger do I need for this EC3 battery? — You'll need a LiPo charger compatible with 4S batteries and equipped with an EC3 charging port (or an EC3 adapter cable if your charger uses XT60 or other connectors). The charger should support balanced charging to maintain cell voltage equalisation and extend battery lifespan. RC Model Shop staff can recommend suitable chargers when you purchase this battery.
• How does the 50C discharge rating compare to other LiPo batteries? — The 50C rating is a solid mid-range specification that balances performance and reliability. Higher-rated batteries (75C, 100C+) deliver more current but often cost more and may be unnecessary for recreational driving. Lower-rated batteries (25C, 35C) restrict top-end performance and may not suit competitive racing applications. The 50C rating on this Radient pack makes it versatile for both competitive racing and casual hobby use.
