Key Features

• 4S Cell Configuration (14.8V Nominal) — The four-cell arrangement delivers 14.8 volts nominal output, which is the standard voltage for countless brushless RC vehicles available in the UK market, including many popular 1/10 scale models. This voltage is optimised to work seamlessly with most modern brushless motor and ESC combinations without requiring voltage regulators or adapters.
• 5000mAh Capacity — The 5000 milliamp-hour capacity provides extended runtime during your RC sessions, allowing you to enjoy longer periods of driving before requiring a recharge. For competitive racers and weekend bashers alike, this capacity strikes an excellent balance between weight and duration.
• 50C Continuous Discharge Rating — The 50C discharge rate means this battery can safely deliver 250 amps of continuous current (50 × 5 amps), making it suitable for high-performance brushless motors and demanding ESC systems. This robust discharge capability ensures your battery can match the power requirements of speed-focused builds without voltage sag or cell stress.
• XT90 Connector — The XT90 connector is one of the most widely adopted battery connectors in the RC hobby, particularly favoured in the UK RC community for its secure connection, low resistance, and reliable performance across diverse applications including RC cars, trucks, buggies and crawlers.
• Soft Case Design — The protective soft case enclosure guards your cells during transport and storage whilst keeping the overall package compact and lightweight, making this battery convenient for taking to track events, bash sessions, or RC clubs throughout the UK.
• Compact Dimensions — At just 125mm in length, 45mm in width, and 32mm in height, this battery pack fits comfortably into the battery compartments of most modern RC vehicles, whether you're building a competitive racer or a high-speed basher.
• Authorised Radient Product — Purchased from RC Model Shop, you can be confident this is a genuine Radient battery with full manufacturer support and warranty protection, not a counterfeit or grey-market product.

Technical Performance

The Radient LiPo 4S 5000mAh 14.8V 50C XT90 represents modern lithium polymer battery engineering optimised for the demanding world of RC hobby vehicles. The 50C discharge rating is particularly impressive, demonstrating that Radient has engineered this pack with high-current applications in mind. For context, a 50C rating on a 5000mAh battery means the pack is engineered to safely deliver 250 amps continuously, which translates to rapid acceleration, consistent mid-pack performance, and reliable power delivery even under sustained full-throttle driving conditions. This makes the battery equally at home powering a high-speed 1/10 scale buggy through a competitive race track or driving a heavyweight RC truck through demanding bash terrain. The 14.8V nominal voltage output is industry-standard for 4S applications, ensuring compatibility with the broadest possible range of brushless ESC units and motors available to UK RC enthusiasts. The 405-gram weight is reasonable for a 5000mAh pack and contributes to balanced vehicle weight distribution across most RC platforms. Construction quality is paramount with LiPo batteries, and Radient's reputation in the RC community reflects consistent attention to cell matching, internal resistance optimisation, and protective circuitry. The soft case design employs durable materials that protect against minor impacts and punctures during transport and operation, whilst the XT90 connector provides gold-plated contacts that resist oxidation and maintain low electrical resistance across thousands of charge-discharge cycles. Storage, handling and safety are important considerations with any LiPo battery, and the 14+ age recommendation reflects the responsibility required when working with lithium polymer cells.

Frequently Asked Questions

• What vehicles can I use the Radient 4S 5000mAh LiPo battery with? — The 14.8V nominal output and XT90 connector make this battery compatible with any brushless RC vehicle designed for 4S LiPo power, including most 1/10 scale buggies, trucks, short-course vehicles, and crawlers available in the UK market. Always verify your specific model's battery requirements before purchase.
• Is the Radient LiPo 4S 5000mAh suitable for beginners? — Whilst the battery itself is robust and reliable, LiPo batteries require responsible handling, proper charging with a compatible LiPo charger, and appropriate storage. The 14+ age recommendation reflects this requirement. Beginners should familiarise themselves with LiPo safety practices before using this battery, and it is recommended to use a balance charger and monitor cells during charging.
• How long does the Radient 5000mAh battery last per charge? — Runtime depends heavily on your specific RC vehicle, motor KV rating, driving style, and terrain. As a general guide, a 5000mAh battery in a 1/10 scale buggy typically provides 15-25 minutes of driving time, though competitive drivers may see shorter runtimes at full throttle whilst bashers may achieve longer periods at moderate throttle levels.
• What charger do I need for this battery? — This 4S LiPo battery requires a dedicated LiPo-compatible charger, preferably a balance charger that can monitor individual cell voltages. A good quality LiPo balance charger is essential for extending battery lifespan and ensuring safe charging. Standard NiMH chargers cannot be used with LiPo batteries.
• What makes the 50C discharge rating important? — The 50C rating indicates the maximum continuous current the battery can safely supply. For a 5000mAh battery, 50C equals 250 amps maximum continuous discharge. This high rating means the battery can power demanding brushless setups without voltage sag, providing consistent acceleration and performance throughout your driving session.
• How does this compare to lower C-rated batteries? — A 50C battery like this can deliver more sustained current than lower-rated alternatives, which means better acceleration, more consistent mid-pack power, and the ability to handle more powerful motor and ESC combinations. If you're driving a high-performance brushless RC vehicle, a 50C or higher rating is recommended.
• Is the XT90 connector the right choice for my RC vehicle? — The XT90 is one of the most popular connectors in the UK RC hobby community. Check your vehicle's battery port and ESC connector — if they accept XT90, this battery is an excellent choice. If your vehicle uses different connectors (such as XT60, Deans, or others), you would need an adapter or a different battery.
• How should I store this battery? — LiPo batteries should be stored in a cool, dry location away from direct sunlight, ideally in a LiPo storage bag designed for safe containment. Store at approximately 50% charge state if you won't be using the battery for extended periods. Never store LiPo batteries in sealed containers without ventilation, and keep them away from flammable materials.
