• Compact 106 x 36 x 28mm Footprint — The thoughtfully engineered dimensions allow this battery to fit into tight battery compartments where larger packs simply won't fit, making it perfect for scale RC models and vehicles with space constraints.
• Soft Case Protection — The battery arrives in a protective soft case that shields the cells from minor impacts during storage, transport, and handling, extending the lifespan of your investment.
• Suitable for Age 14+ — This battery carries a manufacturer age recommendation of 14 years and upwards, reflecting the responsibility required when handling lithium polymer batteries safely.

Technical Performance

The Radient LiPo 3S 3000mAh 11.1V 30C EC3 battery represents solid engineering focused on real-world reliability. The 30C discharge rating provides headroom for peak current demands whilst maintaining stability under load, making this battery forgiving enough for learners operating ready to run RC cars yet capable enough for experienced racers pushing their vehicles hard. The three-cell lithium polymer configuration delivers a nominal voltage of 11.1 volts, which is the industry standard for 3S applications and ensures compatibility with the vast majority of 3S-rated brushless ESCs and motors available in the UK RC market. The 3000mAh capacity is carefully sized to provide genuine runtime without unnecessary weight — a full discharge on typical 30-50 watt applications should yield 20-40 minutes of continuous operation depending on your specific vehicle and driving style. The EC3 connector uses gold-plated contacts to ensure minimal resistance and maximum conductivity, reducing voltage sag during peak current draws and improving overall efficiency. Construction quality reflects Radient's reputation in the hobby; the cells are balanced and tested, the case is durable yet flexible, and the overall build quality inspires confidence in field use. Whether you're operating an RC buggy, an RC truggy, or any EC3-equipped electric RC vehicle, this battery delivers the consistent performance that makes the difference between frustration and enjoyment in your RC hobby.

Frequently Asked Questions

• What RC vehicles is the Radient 3S 3000mAh 11.1V 30C battery compatible with? — This battery is compatible with any RC car, RC plane, or RC quadcopter equipped with an EC3 connector that is rated for 3S LiPo power. This includes countless popular RC models available in the UK such as electric RC buggies, ready to run RC cars, and numerous hobby-grade aircraft and racing drones. Check your vehicle's manual or specifications to confirm it supports a 106 x 36 x 28mm battery footprint and 3S voltage.
• Is the Radient 3S LiPo suitable for beginners? — Yes, this battery is suitable for beginners aged 14 and upwards who are learning to operate RC vehicles. The 30C rating provides stable power delivery, and the compact size makes it easy to install in most ready to run RC cars. However, beginner RC operators must follow all manufacturer safety instructions for lithium polymer battery handling, charging, and storage. Always charge under supervision using a dedicated LiPo balance charger, never overcharge, and store in a cool, dry place.
• How long will this battery last on a single charge? — Runtime depends on your specific vehicle's power consumption, driving style, and terrain. As a general guide, the 3000mAh capacity should deliver 20 to 40 minutes of continuous running on a typical 30-50 watt RC vehicle. Racing applications that draw higher current will experience shorter runtime, whilst gentle driving applications may achieve longer sessions.
• What is the difference between the 30C rating and other discharge ratings? — The 30C rating indicates continuous discharge capability; multiply the capacity (3000mAh) by the discharge rate (30C) to find maximum continuous amps: 3000 × 30 = 90 amps maximum. Higher C ratings allow more current draw suitable for high-performance motors; lower C ratings are adequate for lower-powered applications. This 30C rating is versatile and suits most mainstream hobby RC vehicles.
• Do I need a special charger for this LiPo battery? — Yes, you must use a dedicated LiPo battery charger capable of balance charging. Standard NiMH chargers will damage lithium polymer batteries. A quality LiPo charger will balance the individual cells and protect against overcharging, extending battery life and ensuring safety.
• What is the EC3 connector and why does it matter? — The EC3 (E-flite Connector 3) is a standardised battery connector widely adopted across the RC hobby in the UK and worldwide. It features gold-plated contacts that provide low-resistance connections, reducing power loss and voltage sag. The EC3 is secure, foolproof to connect, and recognised across countless RC applications, making it a sensible choice for compatibility and reliability.
