Key Features

• 2S LiPo Configuration (7.4V) — This battery delivers two cells in series for a nominal voltage of 7.4 volts, which is the standard requirement for countless RC models including RC cars, RC buggies, RC trucks and RC crawlers throughout the UK hobby. Two-cell LiPo packs offer an excellent balance between voltage, weight and size, making them one of the most popular battery configurations in the RC market today.
• 4000mAh Capacity — With 4000 milliampere-hours of stored energy, this battery pack provides genuine runtime for extended RC sessions. The 4000mAh capacity is substantial enough to deliver meaningful flight or drive time without being unnecessarily heavy, making it an ideal middle ground for serious RC enthusiasts who want to maximise their time at the track or field without carrying excessive weight.
• 50C Discharge Rating — The 50C rating means this battery can safely discharge at 200 amps (50 times its 4Ah capacity), providing ample power for high-performance RC models, brushless motors, and demanding driving styles. This discharge rating ensures the battery can keep pace with modern brushless RC setups whilst maintaining voltage stability under load, which translates directly to consistent throttle response and predictable handling characteristics.
• XT60 Connector — The XT60 is an industry-standard connector format trusted by RC pilots and drivers worldwide. This gold-plated connector ensures reliable current transfer and is widely compatible with brushless ESCs, chargers and charging leads used in modern RC setups across the UK hobby. If your RC model or equipment already features XT60 connectors, installation is straightforward and requires no additional adapters or modifications.
• Soft Case Protection — The battery arrives in a protective soft case that shields the cells from physical damage during storage, transport and charging. This case design allows for safe stacking of multiple batteries and keeps your Radient LiPo pack organised in your RC gear bag, extending the lifespan of your investment and maintaining cell integrity over time.
• Compact Form Factor — At just 137mm in length and weighing only 221g, this battery pack is designed to fit into space-constrained battery compartments without requiring major chassis modifications. The compact dimensions make it ideal for RC models with limited internal space, whilst the reasonable weight ensures balanced handling characteristics and optimal performance across a range of RC vehicle types.
• Age 14+ Recommendation — This product is designated for users aged 14 and above, reflecting the handling and safety knowledge required for responsible LiPo battery operation. Lithium polymer batteries demand proper care, charging protocol and storage conditions, making them most suitable for mature users who understand battery safety fundamentals and can follow manufacturer guidelines conscientiously.

Technical Performance

The Radient LiPo 2S 4000mAh 7.4V 50C represents a thoughtfully engineered power solution that combines substantial capacity with robust discharge capability. The 50C continuous discharge rating is particularly significant for modern RC applications, where brushless motor systems and high-torque servo requirements demand consistent, stable power delivery under demanding conditions. With a maximum discharge current of 200 amps, this battery can reliably power brushless RC cars, RC trucks and other high-performance models without voltage sag or performance degradation. The two-cell configuration delivers 7.4 volts nominal (approximately 8.4 volts fully charged), which is the industry-standard voltage for thousands of RC models currently in use across the UK market. The 4000mAh capacity strikes an important balance between runtime and weight; it provides sufficient capacity for meaningful driving sessions lasting 15-25 minutes depending on driving style and motor choice, whilst keeping pack weight to a practical 221g that won't compromise your RC model's handling or acceleration characteristics. Built with modern lithium polymer cell technology, the battery features internal protection circuitry and is housed in a protective soft case that guards against physical damage. The compact dimensions of 137 x 43 x 19mm have been carefully designed to fit into most RC vehicle battery bays without requiring extensive modification. Whether you're racing a ready-to-run RC buggy, bashing an RC truck through rough terrain, or running a precision RC crawler, the Radient LiPo 2S 4000mAh 7.4V 50C provides the stable, responsive power delivery that modern RC enthusiasts expect. The XT60 connector features gold plating for enhanced electrical conductivity and durability, ensuring reliable power transfer through thousands of connect-disconnect cycles.

Frequently Asked Questions

• Is the Radient LiPo 2S 4000mAh 7.4V 50C suitable for beginners to the RC hobby? — This battery pack is recommended for users aged 14 and above, making it appropriate for older teenagers and adults. Whilst the battery itself is straightforward to use once installed, LiPo battery operation does require understanding proper charging procedures, storage conditions and safety protocols. Beginners should familiarise themselves with LiPo battery fundamentals before purchasing, including the importance of using a dedicated LiPo charger, avoiding over-discharging, and storing batteries in a safe, fireproof location. If you are brand new to RC, we recommend discussing battery operation with experienced RC enthusiasts or consulting manufacturer guidance before your first charge.
• What RC models will this battery work with? — The Radient LiPo 2S 4000mAh 7.4V 50C is compatible with any RC model designed to accept a 2S LiPo battery with an XT60 connector. This includes many ready-to-run RC cars, RC buggies, RC trucks, RC crawlers and specialist RC vehicles. Check your RC model's documentation to confirm 2S LiPo compatibility and verify that your model features an XT60 connector or that you have a suitable adapter lead available. If your model uses a different connector standard, adapter leads are widely available, though we recommend consulting with an RC specialist to ensure compatibility.
• How long will this battery last per charge? — Runtime depends significantly on your specific RC model, driving style, motor choice and terrain. As a general guide, the 4000mAh capacity typically provides 15-25 minutes of continuous driving for most RC cars and RC trucks, though lighter models and smooth surfaces may extend this, whilst heavy bashing and rough terrain will reduce runtime. The 50C discharge rating ensures consistent power delivery throughout the discharge cycle, meaning you'll enjoy full throttle response and voltage stability rather than the fade-out commonly associated with lower-rated batteries.
• What charger do I need for this Radient LiPo battery? — You must use a dedicated LiPo battery charger with 2S LiPo capability. Do not attempt to charge this battery with standard NiMH or NiCd chargers, as this will damage the cells and create a serious fire hazard. Look for chargers labelled as compatible with 2S LiPo packs; most modern RC chargers support this configuration. The charger should feature a balance charging port to maintain cell voltage equilibrium and protection against over-charging. We recommend consulting with RC Model Shop staff if you need guidance selecting an appropriate charger for your setup.
• Can I use this battery in my transmitter or receiver? — No, the Radient LiPo 2S 4000mAh 7.4V 50C is designed exclusively for powering RC motors and drive systems. Transmitters and receivers require dedicated batteries with appropriate connectors and discharge characteristics. Never attempt to use a high-discharge 50C LiPo pack for powering radio equipment, as this could damage sensitive receiver components.
• How should I store this battery? — Store the Radient LiPo 2S 4000mAh 7.4V 50C in its soft case in a cool, dry location away from direct sunlight and heat sources. If you're storing the battery for extended periods, charge it to approximately 50% capacity before storage, as this reduces stress on the cells and extends long-term lifespan. Never store a fully charged or fully discharged battery for weeks at a time. Keep the battery away from moisture, flammable materials and high temperatures. A fireproof storage box or safe is recommended for storing multiple LiPo packs.
