With a soft case design and straightforward specifications, this 4S battery integrates seamlessly into your existing RC setup, whether you're running a 1/10 scale rock crawler, a high-speed stadium truck, or an off-road buggy that demands consistent power delivery throughout your driving session.

At 2200mAh capacity with a 50C discharge rate, this battery provides the electrical current needed for responsive acceleration and sustained high-performance driving. The 14.8V nominal voltage (when fully charged) matches the requirements of 4S-compatible ESCs and motors, ensuring you get the exact power level your model was designed to receive. This is not a beginner's first battery—it's a proper performance power pack for RC pilots aged 14 and upwards who understand LiPo battery handling and safety protocols.

Key Features

• 4S Cell Configuration (14.8V) — Four lithium polymer cells in series deliver 14.8V of nominal power, which is the standard voltage requirement for 4S-compatible RC electronics, motors and ESCs, ensuring full compatibility with a wide range of modern RC models without over-voltage or under-voltage issues.
• 2200mAh Capacity — The 2200 milliamp-hour rating provides sufficient energy storage for extended driving sessions whilst keeping the overall weight and physical dimensions practical for models where space is at a premium, balancing runtime against portability and response characteristics.
• 50C Continuous Discharge Rate — This 50C rating means the battery can safely deliver up to 110 amps of continuous current (2200mAh × 50C), providing the electrical headroom needed for brushless motors, responsive throttle control and high-speed performance without voltage sag or thermal stress during demanding driving.
• EC3 Connector — The EC3 plug is an industry-standard connector used across thousands of RC models and ESCs in the UK hobby market, ensuring broad compatibility and the ability to quickly swap this battery between compatible models without requiring adapter cables or modifications.
• Soft Case Construction — The flexible soft case design protects the battery cells during transport and storage whilst keeping the overall weight minimal, and the case allows the battery to flex slightly during intense driving without risk of internal cell damage.
• Compact Dimensions (106mm × 34mm × 35mm) — These practical size dimensions fit into battery compartments on modern RC cars, buggies and trucks without excessive bulk, making this battery ideal for models where space-saving is a design consideration and weight distribution matters for handling.
• Lightweight at 0.26kg — Weighing just 260 grams, this battery adds minimal mass to your RC model, preserving the handling characteristics and acceleration response that competitive drivers and keen hobbyists demand from their setups.

Technical Performance

The Radient LiPo 4S 2200mAh 14.8V 50C EC3 battery represents solid engineering with attention to the real-world needs of UK RC enthusiasts. At 14.8V nominal (fully charged to approximately 16.8V), this battery delivers the exact voltage specification required by 4S-rated ESCs and motors, eliminating guesswork about compatibility. The 50C discharge rating is particularly significant—it means this battery can handle sustained high-current draw without voltage sag degradation, which is crucial for maintaining throttle response in brushless RC applications. The 2200mAh capacity sits in the sweet spot for compact RC models: sufficient for 15-20 minute driving sessions depending on driving style and model weight, yet not so large that it compromises the vehicle's weight distribution or fits awkwardly in battery trays. The soft case protects the lithium cells during normal use whilst remaining flexible enough to compress slightly during installation. The EC3 connector is rated for the 110-amp peak current this battery can theoretically deliver, though typical RC driving patterns involve less sustained maximum draw. For users in the UK who invest in quality LiPo chargers and understand voltage monitoring, this Radient battery offers reliable performance across multiple charging cycles. The combination of proven cell chemistry, the established EC3 standard, and Radient's manufacturing credentials makes this a dependable choice for anyone upgrading from basic batteries or expanding their RC battery collection.

Frequently Asked Questions

• Is the Radient 4S 2200mAh LiPo battery suitable for beginner RC pilots? — This battery is recommended for RC enthusiasts aged 14 and upwards with experience handling lithium polymer packs. Beginners should understand LiPo safety protocols including proper charging, storage at rest voltage (around 3.8V per cell), and never leaving a charging battery unattended. If you're new to RC, consider starting with a ready-to-run model that includes a beginner-friendly battery and charger, then upgrade to this performance battery once you've gained experience.
• What RC models are compatible with this 4S LiPo battery? — This battery fits any RC car, RC buggy, RC truck or RC crawler designed for 4S LiPo packs with an EC3 connector. Common compatible platforms include modern 1/10 scale brushless RC vehicles, stadium trucks, and competitive racing buggies. Always verify your specific model's battery specifications before purchasing—check your user manual for voltage requirements and available battery space dimensions.
• How long does this battery last on a full charge? — Actual runtime depends on driving style, motor size, ESC programming and terrain. In typical RC use, expect 15-20 minutes of driving per charge. Aggressive throttle use and high-speed running reduces runtime; gentle driving and lower speed operation extends it. Heavier models with larger motors will consume more power and run shorter than lightweight vehicles.
• What charger do I need for this battery? — Use a quality LiPo-compatible charger capable of 4S (14.8V) charging with balance charging functionality. Balance chargers monitor individual cell voltages and equalise them, maximising battery lifespan and safety. Never use a charger not designed for LiPo batteries, as this risks fire or explosion. RC Model Shop stocks suitable chargers—ask our team for a recommendation matching your needs and budget.
• How does the 50C discharge rate affect performance? — The 50C rating indicates this battery can safely deliver up to 110 amps continuously without overheating or voltage collapse. In practical RC driving, this means the battery maintains stable voltage even during hard acceleration and high-speed runs, translating to responsive throttle control, better traction response and more consistent performance throughout the charge cycle compared to lower C-rating batteries.
• Is the EC3 connector widely compatible? — Yes, EC3 is one of the most common connectors in the RC hobby across the UK. Thousands of modern ESCs, motors and pre-built RC vehicles use EC3 connections. However, some specialist racing models and older equipment may use different connectors (Dean's, XT60, etc.), so always verify your specific model's connector type before assuming compatibility.
• How should I store this LiPo battery? — Store at rest voltage (approximately 3.8V per cell, or 15.2V total for a 4S pack) in a cool, dry place away from direct sunlight and moisture. Check voltage monthly if in long-term storage. Never store a fully charged battery for extended periods, as this stresses the cells and reduces overall lifespan. A LiPo storage bag adds an extra layer of safety.
• What is the difference between 50C and higher C-rating batteries? — A 50C battery is suitable for most recreational RC use and many competitive applications. Higher C-ratings (75C, 100C, etc.) allow greater peak current draw but typically cost more. Unless you're running extremely high-powered motors or seeking marginal performance gains in competition, 50C provides excellent value and reliability for UK RC enthusiasts.
