Key Features

• 3S LiPo Configuration with 11.1V Output — The three-cell lithium polymer design delivers a nominal 11.1V output across the full discharge curve, providing the consistent voltage necessary for stable performance in electric RC applications. This voltage is widely compatible with RC cars, drones, helicopters and other hobby devices that specify 3S power requirements.
• 1400mAh Capacity for Extended Runtime — The 1400 milliamp-hour capacity strikes an ideal balance between weight and runtime, delivering sufficient energy for meaningful operational periods whilst maintaining the low mass essential for responsive handling in RC vehicles. This capacity is particularly well-suited to compact models where battery weight directly affects performance.
• 50C Continuous Discharge Rating — The 50C rating means this battery can safely deliver 70 amps of continuous current (1400mAh × 50C = 70A), enabling rapid acceleration, responsive throttle control, and sustained high-performance running. This rating ensures the pack can handle the demands of fast-paced RC applications without voltage sag or performance degradation.
• EC3 Connector for Universal Compatibility — The EC3 connector is a widely adopted standard in the RC hobby, ensuring this battery integrates with the majority of modern RC cars, drones and hobby devices without requiring adaptors. This connector type provides secure connections and reliable power transfer with minimal resistance.
• Compact Soft Case Design — Measuring just 72mm in length, 36mm in width, and 28mm in height, this battery pack fits into tight battery compartments where larger alternatives cannot. The soft case construction protects the cells whilst remaining flexible enough to squeeze into compact spaces, making this an essential upgrade for modellers working with space-constrained RC platforms.
• Lightweight Construction at 160 Grams Shipping Weight — The light mass of this battery pack contributes to improved acceleration and handling characteristics in RC vehicles, reducing inertia and allowing lighter models to achieve better agility and responsiveness. Lower battery weight translates directly to improved performance for small-scale RC platforms.
• Reliable Radient Brand Manufacturing — Radient is a recognised manufacturer of quality LiPo batteries with a strong reputation in the RC hobby market. This pack represents their commitment to delivering proven chemistry and consistent performance across applications.

Technical Performance

The Radient LiPo 3S 1400mAh 11.1V 50C battery represents a careful balance of performance engineering optimised for applications demanding compact power delivery. The three-cell lithium polymer construction utilises proven LiPo chemistry that has become the industry standard for RC applications throughout the UK and globally. With a 50C continuous discharge capability, this pack is engineered to support sustained high-current demands without the voltage sag that can compromise RC vehicle performance. The 1400mAh capacity, whilst modest by some standards, proves particularly valuable in weight-sensitive applications where every gram matters—from racing drones to lightweight RC cars where mass reduction directly improves acceleration and handling. The EC3 connector represents the practical choice for compatibility, avoiding the need for adapter purchases or modifications to existing RC equipment. The soft case protection keeps cells secure during transport and operation whilst maintaining flexibility for installation in compact battery compartments. Built to Radient's quality standards, this battery pack undergoes quality control processes to ensure consistent cell matching and balanced discharge across all three cells, extending battery life and reliability.

Frequently Asked Questions

• What devices and RC vehicles will this battery power? — The Radient 3S 1400mAh 11.1V 50C battery is compatible with any RC device—including RC cars, drones, helicopters, FPV systems, and hobby electronics—that features an EC3 connector socket and requires 3S (11.1V) power. If your device uses a different connector type like XT60 or Deans, you can purchase an EC3 adapter to enable compatibility. Always verify your device specifications before purchasing.
• Is the Radient 3S 1400mAh battery suitable for beginners? — Yes, this battery is recommended for users aged 14 and upwards, making it appropriate for teenage and adult RC enthusiasts. The compact size makes it ideal for beginners working with smaller RC platforms, and the 50C rating provides responsive performance without the complexity of higher-cell-count batteries. As with all LiPo batteries, users should follow safe charging practices using a dedicated LiPo charger and observe proper storage procedures.
• What does the 50C rating mean and why is it important? — The 50C rating indicates the maximum continuous discharge rate, calculated as 1400mAh × 50C = 70 amps maximum safe discharge. This means the battery can deliver 70 amps of current continuously without damage. A higher C rating supports faster acceleration, more responsive throttle control, and better performance under sustained high-power demands. The 50C rating suits competitive and performance-oriented RC driving.
• How long will this battery run in my RC vehicle? — Runtime depends on your specific RC device's current draw, which varies considerably between models. As a general guide, a device drawing 20 amps continuously would achieve approximately 4.2 minutes of runtime with a 1400mAh battery. Lower-power devices drawing 10 amps might achieve 8-10 minutes. Actual runtime is also affected by driving style, throttle usage, and load conditions. Consult your device manufacturer's specifications for accurate runtime estimates.
• What is the difference between this Radient 50C pack and lower C-rated alternatives? — Lower C-rated batteries (such as 25C or 35C alternatives) have lower maximum discharge currents and deliver less peak power. This results in slower acceleration, reduced responsiveness to throttle input, and potential voltage sag under high-load conditions. The 50C rating of this Radient pack enables significantly better performance, particularly in competitive or high-demand applications. The trade-off is that higher C-rated packs typically cost slightly more.
• Do I need a special charger for this LiPo battery? — Yes, you must use a charger specifically designed for LiPo (lithium polymer) batteries. Standard NiMH chargers cannot safely charge LiPo packs and may cause damage or safety hazards. LiPo chargers offer cell balancing to maintain even voltage across all three cells, extending battery life. RC Model Shop stocks a range of LiPo chargers suitable for 3S packs.
• What are the dimensions and will it fit my RC vehicle? — This battery measures 72mm length × 36mm width × 28mm height with a shipping weight of 0.16kg (160 grams). These compact dimensions are specifically designed for tight battery compartments. Measure your RC vehicle's battery bay before purchasing to ensure adequate space. The soft case provides some flexibility, but the core battery dimensions are fixed.
• Is this battery waterproof? — Whilst the soft case offers some splash protection, LiPo batteries are not fully waterproof and should not be submerged or exposed to prolonged water contact. Water ingress can cause electrical shorts and safety hazards. If you operate an RC vehicle in wet conditions, ensure the battery compartment remains well-sealed and dry, and inspect the battery after use.
