Key Features

• 2-Cell (2S) Configuration at 7.4V — This two-cell lithium polymer arrangement delivers 7.4 volts of nominal voltage, which is the standard power level for countless RC cars, trucks, and other models available to UK buyers, ensuring broad compatibility across the RC hobby market.
• 4000mAh Capacity — The 4000 milliamp-hour capacity provides substantial runtime for extended play sessions, allowing you to enjoy longer periods of uninterrupted fun before needing to recharge, making it ideal for both casual afternoon sessions and more intensive racing or bashing activities.
• 50C Continuous Discharge Rating — This impressive discharge rate (50 times the capacity per hour) means the battery can safely deliver up to 200 amps of continuous current, providing the responsive, high-performance power delivery needed for dynamic driving styles and competitive RC applications without thermal stress or damage.
• Deans (HCT) Connector — The Deans-style connector is one of the most widely recognised and trusted connection standards in the RC hobby, particularly favoured in the UK market for its robust design, secure connection, and minimal voltage drop during operation, ensuring reliable power transfer every time you fly or drive.
• Compact Physical Dimensions — Measuring just 137mm long, 43mm wide, and 19mm tall, this battery pack fits into tight battery bays without requiring extensive modifications or custom mounting solutions, making it perfect for models with limited space availability.
• Soft Case Protection — The soft case construction protects the battery cells from minor impacts and abrasions during transport and storage, whilst remaining lightweight enough not to compromise your model's performance or weight distribution characteristics.
• Proven Radient Quality — Radient is a recognised manufacturer of high-quality lithium polymer batteries trusted by RC enthusiasts across the UK, delivering consistent cell matching, reliable performance, and excellent cycle life across their product range.

Technical Performance

The Radient LiPo 2S 4000mAh 7.4V 50C battery pack represents solid engineering designed specifically for demanding RC applications. The 7.4-volt nominal output is perfectly calibrated for modern brushless ESCs and motor combinations commonly found in competitive and recreational RC cars, trucks, and buggies throughout the UK hobby scene. With a maximum discharge current capability of 200 amps (calculated from the 50C rating multiplied by the 4000mAh capacity), this battery can power high-KV brushless motors and aggressive driving styles without experiencing voltage sag that would otherwise compromise acceleration response or top speed. The 221-gram weight distribution is carefully considered for models designed around 2S battery packs, ensuring balanced handling characteristics and predictable weight transfer during cornering, acceleration, and braking. The soft case construction uses durable material to protect the individual lithium polymer cells within whilst allowing for flexible form factors that conform to various battery bay shapes. The Deans connector features solid gold plating that resists corrosion and maintains low contact resistance even after numerous charge-discharge cycles, preserving power delivery efficiency throughout the battery's operational lifespan. Built-in cell protection within the pack construction helps prevent over-discharge conditions that could permanently damage lithium polymer cells, though proper charger monitoring remains essential for optimal battery longevity.

Frequently Asked Questions

• What RC models are compatible with the Radient 2S 4000mAh LiPo battery? — This battery is compatible with any RC car, truck, or model that accepts a 2S (7.4V) LiPo battery with a Deans (HCT) connector and has a battery bay measuring approximately 137mm in length, 43mm in width, and 19mm in height. This includes numerous popular ready-to-run RC vehicles available across the UK hobby market, from electric RC buggies to RC short-course trucks and beyond.
• How long will this battery last per charge? — Runtime depends on your specific model's motor, ESC programming, and driving style, but the 4000mAh capacity generally provides 15 to 30 minutes of continuous operation in most RC vehicles, with lighter vehicles and more conservative driving extending session length considerably.
• Is the Radient 2S LiPo suitable for beginners? — Yes, this battery is appropriate for hobby-level users aged 14 and upwards. However, all lithium polymer batteries require proper charging equipment and safe handling practices, so users should familiarise themselves with LiPo battery safety procedures before their first charge-discharge cycle.
• What charger do I need for this battery? — You'll need a lithium polymer-compatible battery charger with a 2S balance charging connector (typically JST-XH or similar) to safely charge this pack. Most modern RC battery chargers sold in the UK support 2S charging, making compatible chargers widely available.
• What does the 50C discharge rating mean? — The 50C rating indicates the battery can safely discharge 50 times its capacity (in amps) per hour. For this 4000mAh pack, that means a maximum continuous discharge of 200 amps, providing plenty of power for high-performance driving without stressing the cells.
• How do I store this battery properly? — Lithium polymer batteries should be stored in a cool, dry location at approximately 40% state of charge. Keep the battery in its protective soft case and avoid extreme temperatures. Store away from flammable materials and children's reach, following all LiPo safety guidelines.
• What is included with the battery? — The package includes the Radient LiPo 2S battery pack and a soft protective case for safe transport and storage. You will need to acquire a compatible charger and a model with appropriate battery bay dimensions separately.
