Key Features

• 50C Discharge Rating — This specification indicates the maximum continuous current the battery can safely deliver to your RC model's motor and ESC without degradation or damage. A 50C rating on a 1400mAh pack means maximum safe discharge of 70 amps, providing excellent power delivery for high-performance applications where voltage sag must be minimised.
• 4S Cell Configuration (14.8V Nominal) — Four cells in series deliver a nominal voltage of 14.8 volts, ideal for brushless motor systems and high-performance ESCs commonly found in modern RC cars, trucks, and aircraft. This voltage sweet spot offers excellent performance characteristics without requiring complex dual-battery setups.
• 1400mAh Capacity — The milliamp-hour rating indicates total energy storage, with 1400mAh providing adequate runtime for most RC applications while maintaining a compact form factor. Higher capacity batteries are heavier and bulkier; this pack balances energy availability with weight efficiency.
• XT60 Connector — The XT60 is the industry-standard connector for mid-to-high performance RC applications across cars, trucks, and drones throughout the UK and globally. This connector offers excellent current-carrying capacity, secure connection reliability, and universal compatibility with the vast majority of modern ESCs and charging equipment.
• Compact Dimensions (71 x 31 x 37mm) — Measuring just 71mm in length, 31mm in width, and 37mm in height, this battery pack fits into restrictive battery bays and compartments where space is at a premium. Compact battery placement improves your RC model's centre of gravity and aerodynamics, particularly valuable in drone and aircraft applications.
• Lightweight Construction (180g Shipping Weight) — At under 200 grams including packaging, this battery minimises weight penalty while delivering substantial power. Lower battery weight means improved acceleration, handling response, and overall performance for your RC model.
• Soft Case Design — The flexible soft case protects the battery cells from physical damage during transport, storage, and use whilst remaining flexible enough to fit into tight spaces. This construction method is lighter and more practical than rigid hard cases for field use.
• Trusted Radient Brand — Radient batteries are recognised throughout the RC hobby for consistent quality, reliability, and performance. Choosing an established brand gives you confidence that the battery has been properly manufactured, tested, and balanced before reaching you.

Technical Performance

The Radient LiPo 4S 1400mAh 14.8V 50C battery represents excellent engineering for compact, high-performance RC applications. With a 50C continuous discharge rating, this pack is engineered to deliver up to 70 amps of continuous current, making it suitable for demanding brushless motor systems and high-performance electronic speed controllers (ESCs) found in competitive RC cars UK, racing drones, and high-speed aircraft. The 4S configuration provides 14.8 volts nominal voltage, which sits perfectly within the optimal operating range for modern brushless motors rated for 4S applications. The 1400mAh capacity ensures adequate runtime for typical flying or driving sessions—usually 8 to 15 minutes depending on throttle usage and motor power consumption—whilst the compact 71 x 31 x 37mm dimensions mean the battery fits into restricted spaces without requiring major chassis modifications. The XT60 connector is gold-plated for optimal electrical conductivity and is rated to handle the high currents this pack can deliver safely. The soft case construction protects internal cells whilst remaining flexible for field storage and transport. Radient's manufacturing process ensures proper cell balancing and quality control throughout production, resulting in consistent performance across multiple charge cycles. The battery's internal resistance is engineered to minimise voltage sag during high-demand acceleration bursts, keeping your RC model responsive and lively throughout the flight or drive session.

Frequently Asked Questions

• What does the 50C discharge rating mean and why does it matter? — The 50C rating indicates the maximum safe continuous current the battery can deliver. Multiplying capacity by the C rating (1400mAh × 50C = 70 amps) tells you the peak safe discharge current. Higher C ratings mean better performance under heavy throttle load with less voltage sag, which translates to more responsive acceleration and more consistent power delivery throughout your flight or drive session.
• Is this battery suitable for beginners in RC car UK hobbies? — Yes, this Radient battery is suitable for responsible users aged 14 and above. However, safe LiPo battery handling requires understanding proper charging procedures, storage practices, and connection protocols. If you're new to LiPo batteries, we recommend speaking with our experienced team at RC Model Shop before your first charge—we provide expert guidance on safe battery management practices.
• What vehicles or applications is this 4S battery compatible with? — This 4S 14.8V battery suits any RC model equipped with a 4S-rated brushless motor and ESC featuring an XT60 connector. Applications include small-to-medium brushless RC cars, racing drones, FPV multicopters, electric RC aircraft, and specialty RC helicopters. Always verify your vehicle's documentation confirms 4S compatibility before purchase.
• How long does this battery last on a single charge? — Runtime depends entirely on motor power consumption and throttle usage, but typically ranges from 8 to 15 minutes for most RC applications. Lighter vehicles with smaller motors may achieve 15+ minutes; high-power racing applications might use the battery in 8 minutes of continuous full throttle. We recommend purchasing multiple batteries to maximise your flying or driving time.
• What charger do I need for this battery? — You'll need a dedicated LiPo battery charger with an XT60 charging connector (or an adapter from XT60 to your charger's connector). Many modern RC chargers support 4S charging with balance-lead options. Never attempt to charge LiPo batteries with standard alkaline or lead-acid chargers—always use a proper LiPo-compatible charger to prevent fire risk and battery damage.
• Is the XT60 connector the right size for my RC model? — XT60 connectors are industry-standard on mid-to-high performance RC equipment across the UK. Check your vehicle's existing battery connector; if it's XT60, this battery is a perfect match. If your model uses different connectors (such as T-plug or EC3), you'll need a compatible adapter or a different battery with matching connectors.
• How should I store this battery safely? — Store LiPo batteries in a cool, dry location away from metal objects that could cause short circuits. Avoid storage in hot cars or direct sunlight. Ideally, store at roughly 50% charge in a dedicated LiPo storage bag or fireproof container. Never store fully charged or fully depleted. Check occasionally that the battery isn't swelling, which indicates internal damage.
