Key Features

• 3S Cell Configuration (11.1V) — This three-cell configuration delivers 11.1 volts nominal voltage, which is the standard voltage specification for countless RC cars, trucks, and aircraft designed in the UK and worldwide. The 11.1V output provides excellent power delivery whilst maintaining compatibility with a broad range of electric RC models and speed controllers.
• 5000mAh Capacity — The 5000 milliamp-hour capacity provides substantial runtime for recreational use, allowing you to enjoy extended driving sessions without constantly swapping batteries. This capacity is particularly effective for 1/10-scale and 1/8-scale RC vehicles, delivering both reasonable flight time and sufficient power for aggressive driving styles.
• 50C Discharge Rating — The 50C continuous discharge rating means this battery can safely deliver 250 amps of current (50 times the 5Ah capacity), making it suitable for high-performance applications including fast acceleration, demanding climbs on RC crawler courses, and sustained high-speed running. This rating ensures the battery can handle the demands of modern brushless motors without voltage sag or performance degradation.
• Deans (HCT) Connector — The Deans HCT connector is one of the most widely recognised and trusted battery connectors in the RC hobby, offering secure, low-resistance connections that are both reliable and user-friendly. If your RC model is already equipped with a Deans connector, this battery will integrate seamlessly without the need for adapter cables or soldering.
• Soft Case Construction — The protective soft case keeps your battery safe during storage, transport, and use. This flexible case allows for safe stacking in your RC bag or pit box and provides excellent cushioning against impacts and drops.
• Compact Dimensions — Measuring just 125 x 44 x 31 millimetres, this battery pack maintains a compact profile that fits comfortably into most modern RC chassis designs. The careful balance of size and capacity means you get excellent runtime without excessive weight or bulk that could compromise vehicle handling.

Technical Performance

The Radient LiPo 3S 5000mAh 11.1V 50C battery is engineered to meet the demands of contemporary electric RC models across the UK and beyond. The 50C discharge rating represents the continuous amperage the pack can safely deliver, which translates directly to how quickly the battery can feed power to your speed controller and motor. For perspective, a 50C discharge rating on a 5000mAh pack allows for 250 amps of continuous current draw, making this battery suitable for high-performance brushless motors commonly found in competitive RC cars, aggressive bashers, and performance-focused builds. The 11.1V nominal voltage is industry-standard for 3S applications, meaning any ESC and motor combination rated for 3S operation will be perfectly compatible. The soft case construction protects the internal cell arrangement during the rigours of RC use, whilst the Deans HCT connector ensures minimal voltage drop and maximum reliability. At 0.39 kilograms (approximately 860 grams), the battery weight is reasonable for its capacity and discharge rating, making it suitable for balanced vehicle geometry. The engineering quality and build standards from Radient ensure consistent performance across charge cycles, helping you get maximum value from your investment in RC hobby equipment.

Frequently Asked Questions

• What vehicles is this 3S LiPo battery compatible with? — This battery is compatible with any RC car, truck, aeroplane, or other electric RC model that features a Deans connector and is rated for 3S (11.1V) LiPo batteries. Common applications include 1/10-scale and 1/8-scale electric RC cars and trucks, FPV racing drones, and RC aircraft. Always verify that your specific vehicle's electronic speed controller (ESC) is rated for 3S operation before using this battery.
• How long will this battery last on a single charge? — Runtime depends entirely on your vehicle's motor power, gearing, driving style, and terrain. A 5000mAh battery in a typical 1/10-scale RC car might provide 20-40 minutes of continuous use, though aggressive acceleration and high-speed running will reduce this. Conservative driving on flat terrain will extend runtime considerably.
• Is the Radient 3S 5000mAh 50C battery good for beginners? — Yes, this battery is suitable for users aged 14 and above, including beginners who already own a compatible RC vehicle. The 50C discharge rating makes it versatile enough for both casual recreational use and more demanding performance applications. However, beginners should always follow proper LiPo safety procedures, including using a LiPo charger, avoiding over-discharging, and storing the battery in a cool, dry place.
• What does the 50C discharge rating mean in practical terms? — The 50C rating indicates this battery can safely deliver 250 amps of continuous current (5Ah capacity × 50C = 250A). This means it's suitable for high-performance brushless motors and won't experience excessive voltage sag even under demanding loads. In simpler terms, a higher C rating means the battery can handle more aggressive driving and faster acceleration without performance loss.
• Do I need a special charger for this LiPo battery? — Yes, you must use a charger specifically designed for LiPo batteries. Standard NiMH chargers are not compatible and could damage the battery or create safety hazards. Your LiPo charger should support 3S charging and allow you to set the appropriate charge current (typically between 2-5 amps for a 5000mAh pack).
• What's the difference between this Radient battery and premium alternatives? — Radient batteries offer excellent value for money, delivering reliable performance at competitive UK pricing. Whilst some premium brands may offer slightly higher cycle life or marginal performance improvements, the Radient 3S 5000mAh 50C battery performs exceptionally well for the price and is trusted by many RC enthusiasts across the UK. The choice between brands often comes down to budget and personal preference rather than significant performance differences.
• Can I use this battery in the rain or wet conditions? — Whilst the battery itself is relatively moisture-resistant, LiPo batteries should not be immersed in water. If your RC vehicle gets wet, ensure the battery is removed and the connector is dried thoroughly before recharging. Never charge a wet battery.
• How should I store this battery when not in use? — Store the Radient battery in a cool, dry location (ideally around room temperature) with a charge level of approximately 3.7-3.85 volts per cell (11-11.55V for a 3S pack). The protective soft case helps prevent damage and accidental short circuits. Avoid storing in extreme heat or cold, and never store in direct sunlight or near heat sources.
