Key Features

• 4-Cell (4S) Configuration at 14.8V — The four-cell arrangement provides 14.8 volts nominal output, delivering the elevated power delivery required for performance-focused RC vehicles and aircraft compared to lower-voltage 2S or 3S alternatives. This voltage is the sweet spot for many modern RC ESCs and motor combinations, ensuring your electronics operate within their optimal range.
• 1400mAh Capacity — This capacity offers a practical compromise between weight and runtime, allowing your RC model to operate for a reasonable duration whilst remaining light enough to enhance acceleration and handling characteristics. The 1400mAh rating makes this pack suitable for smaller RC cars, drones, and lightweight RC aircraft where every gram of additional weight impacts performance.
• 50C Continuous Discharge Rating — The 50C rating means this battery can safely deliver 70 amps continuously (1.4Ah × 50C = 70A), providing explosive acceleration and responsive power delivery for aggressive driving or flying. This high discharge capability ensures minimal voltage sag under heavy load, maintaining consistent performance throughout the charge cycle and delivering the crisp throttle response demanded by competitive racers.
• Deans-Style (HCT) Connector — The Deans connector is one of the most widely recognised and adopted connector types across the RC hobby in the UK and worldwide. This universal compatibility means your battery connects directly to thousands of existing RC vehicles, ESCs, and chargers without requiring expensive adapter cables or modifications to your setup.
• Compact Dimensions — At 71mm length, 31mm width, and 37mm height, this pack fits into the restricted battery compartments found on modern racing vehicles, compact buggies, and smaller RC aircraft. The compact profile allows you to position weight centrally within your chassis for optimum handling and balance characteristics.
• Soft Protective Case — The included soft case provides basic impact protection and helps prevent accidental short circuits during storage and transport. The case design minimises additional weight whilst offering practical protection for your battery investment.
• Featherweight Design at 180 Grams — The total shipping weight of just 180 grams (0.40 lbs) keeps your RC model lightweight and responsive, directly improving acceleration, braking, and cornering capabilities. Every gram saved in the battery translates to better performance metrics across the board.

Technical Performance

The Radient LiPo 4S 1400mAh 14.8V 50C battery represents solid engineering focused on delivering practical performance for intermediate and advanced RC hobbyists. The 50C discharge rating is among the higher specifications for packs of this capacity, meaning the internal cell construction prioritises low internal resistance and efficient power delivery. This engineering approach ensures minimal voltage drop even during sustained high-current draws, a critical factor when you're demanding maximum power from your brushless motor or demanding acceleration from your RC car setup. The 14.8V nominal voltage output sits perfectly within the operating window of most modern brushless ESCs rated for 3S or 4S LiPo batteries, whether you're running in an RC monster truck, RC buggy, RC truggy, or specialist RC racing machine. The LiPo chemistry itself delivers superior power density compared to older NiMH battery technology still found in some budget RC packages, offering faster charge times, better discharge efficiency, and more consistent voltage output under load. The soft case construction protects the delicate lithium polymer cells from puncture and impact damage whilst adding minimal bulk or weight to your overall RC setup. For applications ranging from RC drone racing to high-speed RC car bashers, from RC helicopter sport flying to dedicated track racing, this battery delivers the performance characteristics and reliability expected from the Radient brand across the UK market.

Frequently Asked Questions

• What RC models is the Radient 4S 1400mAh battery compatible with? — This battery works with any RC vehicle, aircraft, or drone featuring a Deans-style connector and compatible with 4S LiPo power systems. Common applications include 1/10 scale RC buggies, RC monster trucks, RC truggy platforms, RC helicopters, RC quadcopters and FPV drones, and smaller RC aircraft. Always verify your vehicle's manual confirms 4S (14.8V) battery compatibility before use. The Deans connector is one of the most universal standards in RC, so compatibility is typically broad across the hobby community.
• Is the Radient 4S 1400mAh suitable for beginners? — This battery is best suited for intermediate to advanced RC hobbyists with LiPo charging and handling experience. Beginners absolutely must understand proper LiPo battery care, including safe charging procedures using a dedicated LiPo charger, proper storage voltage maintenance, and recognition of damaged or swollen cells. If you're new to the RC hobby, consider starting with ready-to-run RC packages that include appropriate batteries and chargers designed for your specific model. However, if you're upgrading an existing RC vehicle and have LiPo experience, this pack represents an excellent performance upgrade for competitive driving or flying.
• What charger do I need for the Radient 4S battery? — You'll need a dedicated LiPo-compatible charger capable of handling 4S (14.8V) lithium polymer packs. Many modern RC chargers sold across the UK offer 4S LiPo charging capability, often with balance charging features that monitor each individual cell during charging for optimum battery health. Balance chargers are strongly recommended as they extend battery lifespan and improve safety. The Deans connector compatibility means most RC chargers with Deans leads will connect directly to this pack.
• How long does the Radient 4S 1400mAh battery last on a single charge? — Runtime depends entirely on your specific RC model, motor type, ESC programming, driving style, and terrain. As a general guideline, expect 10-25 minutes of sport flying or bashful RC driving with aggressive throttle use, or up to 30-40 minutes with conservative, steady-state operation. Racing applications typically see shorter runtimes due to sustained high throttle inputs. Heavier RC models consume more power than lightweight platforms, so runtime varies significantly between different vehicles.
• What makes the 50C discharge rating important? — The 50C rating indicates this battery can safely discharge 70 amps continuously (1.4Ah × 50C = 70A), providing explosive power delivery without overheating or damaged. Higher C ratings mean less voltage sag under heavy load, delivering more responsive throttle feel and consistent power throughout the flight or drive session. For performance-focused RC racing or aggressive flying, higher C ratings directly translate to better performance characteristics.
• Is storage and maintenance required for this LiPo battery? — Yes, LiPo batteries require responsible storage and maintenance for longevity and safety. Store your battery in a cool, dry location at storage voltage (approximately 3.7-3.85V per cell, or around 15.0V for a 4S pack). Charge to full only immediately before use, then discharge to storage voltage after each session. Inspect cells regularly for swelling, puffing, or physical damage, and retire any battery showing these warning signs. Never leave LiPo batteries unattended whilst charging, and keep them away from flammable materials. Proper LiPo care ensures safe operation and maximises usable lifespan significantly.
