Whether you're piloting an RC car, RC drone, or other hobby-grade models that utilise a Deans (HCT) connector, this 3-cell pack delivers the consistent power and discharge rate required for responsive performance and extended runtime. With a capacity of 1400mAh and an impressive 50C discharge rating, this battery represents an excellent choice for both seasoned RC car UK competitors and dedicated hobbyists seeking dependable energy storage without unnecessary bulk.

This battery pack is specifically engineered to fit RC models that accept a Deans (HCT) plug connection and require 3S 11.1V lithium polymer power. The compact dimensions of 28 x 36 x 72 mm mean this pack slots neatly into battery trays designed for standard small-format cells, making it ideal for tight-fitting compartments where space is at a premium. The soft case construction provides protection against impact and abrasion during transport and storage, whilst maintaining the flexibility needed for easy installation and removal during field sessions. For anyone operating ready to run RC models or competition-grade setups specified for 3S LiPo batteries, the Radient RDNB14003S50H offers outstanding value and proven reliability.

Manufactured by Radient, a recognised name in the RC battery market, this pack combines careful engineering with practical design to meet the exacting standards of modern RC hobby use. The 50C discharge rate ensures your model receives the sustained current delivery needed for acceleration, responsive handling and consistent power delivery throughout the flight or run cycle, whilst the soft case design protects internal cells without adding significant weight to your model.

Key Features

• 3S LiPo Configuration (11.1V) — Three cells in series deliver the standard 11.1 volts required by many RC systems specified for 3S lithium polymer batteries, providing the voltage curve and power characteristics these models are designed to handle. This voltage specification ensures compatibility with the majority of ready to run RC models and battery trays engineered for 3S packs.
• 1400mAh Capacity — The 1400 milliamp-hour capacity offers practical runtime for small to medium RC models, balancing flight or run duration against the compact physical footprint. This capacity is typical for weight-conscious builds where every gram counts and extended battery endurance must be balanced against vehicle performance and handling characteristics.
• 50C Discharge Rating — The 50C continuous discharge rate means this battery can safely deliver 70 amps of current (50 times 1.4 amps), ensuring sufficient power for high-demand motors and electric systems that require instant throttle response and sustained acceleration. A higher C rating directly translates to better performance under load and more responsive vehicle behaviour during demanding manoeuvres.
• Deans (HCT) Connector — This popular plug standard is widely recognised across the RC hobby and fitted to countless ready to run RC models, RC electronics packages and charging systems available throughout the UK. The Deans connector ensures secure connection, minimal voltage drop, and compatibility with standard RC hobby infrastructure without the need for adapter cables or connector conversion.
• Compact Dimensions (28 x 36 x 72 mm) — The deliberately compact physical profile allows this battery to fit into tight battery trays and restricted compartments found on smaller RC models, sport racing designs and competition-grade vehicles where weight and balance are critical performance factors. This small footprint makes the pack ideal for models engineered around tight dimensional specifications.
• Soft Case Construction — The flexible soft case design protects individual cells from external impact, puncture and minor abrasion whilst remaining flexible enough to fit securely into standard battery trays. Soft cases are preferred in many RC applications because they allow for reliable packing in confined spaces and reduce the weight penalty compared to rigid hard cases.
• Approved for Age 14+ — This battery is suitable for users aged 14 and above, reflecting standard RC industry safety recommendations for lithium polymer cells. This age recommendation indicates the product is intended for responsible hobbyists who understand LiPo safety protocols, proper charging procedures and the care required when handling high-performance battery packs.

Technical Performance

The Radient LiPo 3S 1400mAh 11.1V 50C battery pack delivers the technical performance expected of a modern lithium polymer cell engineered for competitive RC use. The three-cell series configuration produces the 11.1 volt nominal output, with a fully charged voltage of approximately 12.6 volts and a safe discharge floor of around 9.9 volts (3.3 volts per cell). The 50C discharge rating ensures this pack can safely deliver sustained current without voltage sag or thermal issues, making it suitable for brushless motor systems, high-performance ESC setups and race-specification RC models demanding instant throttle response. The 1400mAh capacity combined with the 50C rating produces a continuous discharge capability of 70 amps, sufficient for high-demand applications whilst maintaining a realistic physical size and weight profile. The soft case construction provides genuine impact protection without the weight penalty of hard cases, and the standard Deans (HCT) connector eliminates compatibility issues and ensures reliable electrical connection across all major RC brands and compatible equipment available throughout the UK market. Materials engineering focuses on balanced cell chemistry that prioritises both performance and safety, with proper LiPo charging and storage protocols essential for extending pack lifespan and maintaining consistent voltage delivery over multiple charge cycles.

Frequently Asked Questions

• Is the Radient 3S 1400mAh 50C battery suitable for beginners? — This battery is rated for users aged 14 and above, reflecting industry safety standards for lithium polymer cells. Beginner RC pilots can absolutely use this pack, though they should familiarise themselves with proper LiPo charging procedures, safe storage protocols and the correct discharge limits (never discharging below 3.0 volts per cell) before first use. Beginners operating ready to run RC models with existing Deans connectors will find installation straightforward and hassle-free.
• What models is the Radient RDNB14003S50H compatible with? — This battery is designed for RC models that accept Deans (HCT) connectors and are specified to operate on 3S 11.1V lithium polymer power. This includes many ready to run RC cars, RC buggies, smaller RC trucks and similar models available throughout the UK market. Check your model's instruction manual or specification sheet to confirm it accepts 3S packs and uses a Deans (HCT) connector before purchase.
• What does the 50C discharge rating mean? — The 50C rating indicates the maximum safe continuous discharge rate, calculated by multiplying the capacity by the C rating. For this 1400mAh pack, a 50C rating means it can safely deliver up to 70 amps (1.4 amps × 50) continuously without overheating or voltage sag. Higher C ratings provide better performance under high-demand conditions and more responsive throttle behaviour.
• How long will this battery last on a single charge? — Runtime depends on your specific model, motor type and driving style. The 1400mAh capacity is typical for small RC models and will generally provide 10-20 minutes of continuous use on a single charge, though this varies significantly based on current draw. Keeping multiple charged packs available is a common practice among RC enthusiasts to maximise field time.
• Is this battery waterproof? — Whilst the pack itself is not specifically waterproof, the soft case provides splash resistance during normal use. However, lithium polymer batteries should not be deliberately submerged or exposed to standing water. If your RC model is intended for water use, check the model manufacturer's specifications for battery waterproofing recommendations before use in wet conditions.
• How do I charge this battery safely? — Use a balance charger specifically designed for lithium polymer batteries and set to 3S mode. Never use chargers designed for other battery chemistries. Charge in a safe location away from flammable materials, never leave charging batteries unattended, and follow all instructions in your charger's manual. Most RC enthusiasts charge LiPo packs in dedicated charging bags for added safety.
