• Soft Case Construction — The flexible soft case design protects the battery from physical damage during transport and storage whilst keeping the overall weight and bulk to a minimum, making it easy to carry multiple batteries to the track or your favourite RC bashing location.
• Compact Dimensions — Measuring 135mm in length, 42mm in width, and 32mm in height, this battery pack is engineered to fit into the battery bays of most modern RC vehicles without requiring extensive modifications or custom mounting solutions.
• Lightweight Profile — At just 0.42kg shipping weight, this battery offers genuine power without significantly affecting your RC model's weight distribution, allowing you to maintain optimal handling characteristics and performance.
• Age 14+ Recommendation — This product is recommended for users aged 14 and above, reflecting the need for maturity and responsibility when handling lithium polymer batteries, which require proper charging techniques and storage practices.

Technical Performance

The Radient LiPo 4S 4000mAh 14.8V 50C XT60 represents a well-engineered balance between capacity, discharge capability, and physical size that appeals to the discerning RC enthusiast across the United Kingdom. The 14.8V nominal voltage aligns perfectly with the power requirements of most modern brushless motor systems, from mid-range hobby-grade setups to more performance-oriented configurations. The 50C continuous discharge rating is a critical specification that denotes the battery's ability to deliver sustained high current without excessive heat generation or voltage collapse, a characteristic that becomes increasingly important when driving demanding vehicles such as high-speed RC buggies, monster trucks, or competition-level short-course trucks. The 4000mAh capacity provides a meaningful runtime advantage over smaller 3000mAh or 3300mAh alternatives, yet remains light enough not to compromise vehicle handling or weight-sensitive applications. Built with quality lithium polymer cells and housed in a durable soft case, the battery is engineered to withstand the rigours of regular hobby use. The XT60 connector, recognised as the industry standard across contemporary RC vehicles and chargers, eliminates compatibility concerns and ensures you can charge and deploy this battery across multiple vehicles without adapter complexity. This combination of specifications makes the Radient 4S 4000mAh 50C battery a versatile power solution suitable for everything from casual weekend RC car sessions to more intensive driving environments.

Frequently Asked Questions

• What is a 4S LiPo battery and why is it important for RC vehicles? — A 4S LiPo battery contains four lithium polymer cells connected in series, delivering 14.8V nominal voltage (3.7V per cell). This voltage is the standard choice for powering brushless motor systems in modern RC cars, buggies, and trucks across the UK hobby scene. The four-cell configuration strikes an ideal balance between power output and battery size, making it suitable for a vast range of electric RC models without requiring bulky or overly lightweight packs.
• What does the 50C discharge rating mean for my RC? — The 50C rating indicates the maximum safe continuous discharge rate as a multiple of the battery's capacity. For a 4000mAh battery, this equates to a maximum continuous current of 200 amps (50 × 4Ah). This high discharge capability ensures that your brushless motor receives the current it demands without voltage sag, maintaining consistent acceleration and performance even under full throttle conditions.
• Is the Radient LiPo 4S 4000mAh 50C suitable for beginners? — Whilst the battery itself is reliable and straightforward to use, lithium polymer batteries require proper handling, storage, and charging practices. Users must be aged 14 or above and should understand basic LiPo safety before operation. If you're new to RC hobbies, we recommend consulting the comprehensive guides available through RC Model Shop or seeking advice from our experienced team before your first use.
• How long will this battery last on a single charge? — Runtime depends on your specific RC vehicle, motor size, ESC settings, and driving style. Generally, a 4000mAh battery provides longer runtime than smaller 3000mAh or 3300mAh alternatives. Aggressive driving with constant acceleration will reduce runtime compared to steady, moderate driving. We recommend testing with your specific setup to determine expected runtime for your particular vehicle.
• What charger do I need for this battery? — The Radient LiPo 4S 4000mAh requires a charger capable of handling 4S LiPo batteries with XT60 connectors. Most modern RC battery chargers available in the UK support this configuration. The charger must be specifically designed for lithium polymer batteries to ensure safe and proper charging. Avoid using standard nickel-metal hydride (NiMH) chargers, which are incompatible with LiPo technology.
• Can I use this battery with my existing RC vehicle? — This 4S LiPo battery is compatible with any RC vehicle designed to accept 14.8V power via an XT60 connector. Most modern brushless RC cars, trucks, and buggies meet these requirements. However, you must verify that your ESC is rated for 4S LiPo input and that your vehicle's battery bay can accommodate the 135mm × 42mm × 32mm dimensions before purchase.
• How should I store this battery when not in use? — Lithium polymer batteries should be stored at room temperature in a cool, dry location, ideally at around 3.8V per cell (approximately 50% charge state). Never store a fully charged or deeply discharged LiPo battery for extended periods. Use a fireproof storage bag for added safety, and always keep the battery away from flammable materials.
• What is the difference between 50C and other discharge ratings? — The 50C rating represents this battery's continuous discharge capability. Higher C-ratings (such as 75C or 100C) allow greater sustained current delivery and suit high-performance racing applications, whilst lower ratings (such as 25C or 35C) are suitable for more conservative driving styles and lighter-duty applications. The 50C rating in this pack offers excellent versatility for both recreational and semi-competitive RC driving.
