Key Features

• 3S LiPo Chemistry — This battery uses three lithium polymer cells configured in series, providing an 11.1V nominal voltage that is ideal for a vast range of RC equipment including brushless motors, servos, and electronic speed controllers. The 3S configuration offers a sweet spot between voltage and cell count, making it suitable for compact RC models without excessive weight.
• 450mAh Capacity — The 450 milliamp-hour capacity delivers sufficient energy storage for extended run times on small to medium-sized RC models. This capacity is perfectly calibrated for lightweight applications where you want decent flight or run duration without adding unnecessary weight to your model.
• 30C Discharge Rating — The 30C continuous discharge rating means this battery can safely deliver 13.5 amps of continuous current (450mAh x 30C = 13.5A), providing ample power for high-performance applications while maintaining safe operating parameters and extending battery lifespan through conservative discharge characteristics.
• JST Connector — The JST connector is one of the most widely used standards in RC hobby equipment across the UK and worldwide. This universal connection standard ensures compatibility with the vast majority of modern RC receivers, electronic speed controllers, flight controllers, and other RC components, eliminating the need for adapter leads in most situations.
• Soft Case Protection — The protective soft case covering the battery cells provides essential safeguarding during storage, transport, and handling. This protective casing helps prevent physical damage to the battery pack, reduces the risk of accidental short circuits, and extends the overall lifespan of your investment.
• Ultra-Compact Dimensions — Measuring just 56mm in length, 31mm in width, and 14mm in height, this battery is exceptionally compact. The small footprint makes it perfect for models with tight battery compartments, whether you're building a small FPV racing quadcopter, a micro RC car, or any application where space is at a premium.
• Minimal Weight — At only 0.06kg, this battery adds virtually no weight to your RC model. In RC applications, weight is critical to performance—lighter batteries mean faster acceleration, better handling, improved flight characteristics, and more responsive control, making this pack ideal for performance-oriented RC enthusiasts.
• Age Recommendation 14+ — This battery is recommended for users aged 14 and above, reflecting industry standards for lithium polymer battery handling. Responsible use of LiPo batteries requires understanding of proper charging, storage, and discharge procedures, making this age recommendation a sensible safety guideline.

Technical Performance

The Radient LiPo 3S 450mAh 11.1V 30C JST battery represents efficient engineering in a compact form factor. The three-cell configuration delivers 11.1 volts at nominal charge, with a maximum voltage of 12.6V when fully charged. The 30C discharge rating is conservative by modern standards but ensures safe operation across a wide variety of RC applications—this means the battery can continuously deliver 13.5 amps without risk of damage or excessive heat generation. The JST connector features durable gold-plated contacts that resist corrosion and provide reliable electrical connection across hundreds of charge-discharge cycles. Built with quality lithium polymer cells, this battery maintains consistent voltage delivery throughout the discharge cycle, meaning your RC model maintains steady performance until the battery is nearly depleted. The soft case design uses durable polymer material that protects against impact whilst remaining flexible enough to fit into tight battery compartments. For RC car UK applications, RC drones, RC helicopters, and other small-scale models, this battery delivers the power density and reliability you'd expect from a recognised brand like Radient. The 450mAh capacity, whilst modest by some standards, is perfectly suited to ultra-lightweight applications where extended runtime is less critical than low weight and compact size. When paired with appropriate charging equipment and handled with proper LiPo care procedures, this battery will provide consistent, reliable performance across countless charge-discharge cycles.
