Key Features

• 5500mAh Capacity — The substantial 5500mAh energy storage provides extended runtime for your RC model, allowing longer driving sessions and more practice time before requiring a recharge. This capacity sits in the sweet spot for 1/10-scale RC cars and similar models, offering genuine usable flight or drive time without becoming unnecessarily heavy.
• 3-Cell Configuration (3S / 11.1V) — Three LiPo cells configured in series deliver 11.1V nominal voltage, which is the standard power specification for countless electric RC models worldwide. This voltage provides the performance envelope designed into modern brushless motors and electronic speed controllers, ensuring your equipment operates at its intended performance level.
• 30C Continuous Discharge Rating — The 30C rating indicates this battery can safely deliver 30 times its capacity in continuous current (165 amps maximum from this 5500mAh pack). This discharge rate supports responsive acceleration, high-speed runs, and demanding driving styles without voltage sag or heat build-up, making it suitable for both casual bashers and more spirited drivers.
• Deans (HCT) Connector — The Deans connector is one of the most widely used plug types in modern RC hobby applications, particularly among quality electric RC vehicles and aftermarket ESC units. This connector type provides reliable electrical contact and is easy to disconnect, supporting quick battery swaps during extended RC sessions at the track or field.
• Compact Dimensions — Measuring 125 x 44 x 28mm, this pack is engineered to fit in the battery compartments of most modern 1/10-scale RC cars and similarly-sized models. The compact footprint means you can maintain proper weight distribution and balance in your RC chassis without modification or adaptation.
• Soft Protective Case — The battery arrives in a soft case that provides basic protection during transport and storage. This case safeguards the battery terminals and body from accidental shorts and physical damage, extending the operational life of your investment.
• Reliable Radient Brand — Radient manufactures quality LiPo batteries recognised across the RC hobby. The brand's reputation for consistent cell quality and manufacturing standards means you're buying a battery built to perform reliably across multiple charge cycles.

Technical Performance

The Radient LiPo 3S 5500mAh 11.1V 30C battery delivers exceptional value for RC enthusiasts seeking dependable power in a lightweight package. With a nominal voltage of 11.1V when fully charged and a fully-charged voltage of 12.6V (4.2V per cell), this battery matches the power requirements of countless electric RC models designed around 3S LiPo specifications. The 30C continuous discharge capability ensures stable voltage under load, minimising voltage sag during hard acceleration or high-speed runs — a critical factor in maintaining responsive throttle control and consistent performance throughout your driving session. The 5500mAh capacity provides practical runtime, typically offering 15–25 minutes of mixed-pace driving depending on your RC model's motor size, gearing, terrain, and driving style. Built with quality lithium polymer cells, this battery benefits from the inherent advantages of LiPo chemistry: high energy density, excellent power-to-weight ratio, and the ability to deliver peak currents that brushless RC motors demand. The soft case construction protects the cells during handling and storage, whilst the Deans (HCT) connector ensures secure and reliable electrical contact with your RC equipment. Whether powering a 1/10-scale RC car, RC buggy, or other electric RC models specifying 3S power, this battery represents proven engineering from a manufacturer that understands the demands of UK RC hobbyists.

Frequently Asked Questions

• What RC models is the Radient 3S 5500mAh battery compatible with? — This battery is compatible with any electric RC car, truck, buggy or similar model that specifies 3S (11.1V) power and features a Deans (HCT) connector. This includes a vast range of 1/10-scale RC vehicles from various manufacturers. Always verify your RC model's battery requirements and connector type before purchasing, as using the wrong voltage can damage your equipment.
• How long will this battery last per charge? — Runtime depends on multiple factors including your RC model's motor KV rating, gearing, ESC settings, driving style, and terrain. Typically, a 5500mAh pack provides 15–25 minutes of mixed-pace driving on a 1/10-scale RC car. High-speed bashing will consume the battery faster than casual cruising, so many RC enthusiasts purchase multiple batteries to maximise track time.
• Is this suitable for beginners? — Yes, the Radient 3S 5500mAh is suitable for intermediate RC hobbyists and beyond. Beginners should ensure they understand basic LiPo safety (never over-discharge, always charge with a proper charger, store safely) and verify that their RC model is designed for 3S power before use. The 30C discharge rating is conservative enough to be safe in most applications whilst providing sufficient power for spirited driving.
• What charger do I need for this battery? — You will need a LiPo-compatible battery charger capable of charging 3-cell (11.1V) packs. Modern multi-chemistry chargers, balance chargers, and dedicated LiPo chargers are widely available across the UK. Ensure your charger supports the Deans (HCT) connector type or use an adapter cable. Never use a standard NiMH charger with LiPo batteries, as this will damage the cells.
• Can I use this battery with my existing RC equipment? — Check that your RC model specifies 3S (11.1V) power requirements and features a Deans (HCT) connector. If your model uses a different connector (such as XT60 or Traxxas iD), you will need an adapter cable. If your model specifies 2S or 4S power, this 3S battery will not be appropriate and may cause equipment damage.
• How should I store this battery? — Store your Radient LiPo battery in a cool, dry place away from direct sunlight. Many RC enthusiasts store LiPo packs in fireproof bags or boxes as a safety precaution. For long-term storage (more than a week), discharge the battery to approximately 50% charge level to reduce cell stress. Keep the battery in the supplied soft case to protect it from physical damage.
• What is the 30C rating and why does it matter? — The 30C rating indicates the maximum continuous discharge current relative to the battery's capacity. For this 5500mAh pack, 30C equals a maximum continuous discharge of 165 amps. A higher C rating allows the battery to deliver power more efficiently and with less voltage sag during high-demand situations such as acceleration or climbing steep terrain, resulting in more responsive vehicle performance.
