Key Features

• 6500mAh Capacity — This generous capacity ensures extended run times compared to smaller capacity packs, meaning you'll spend more time driving, flying or piloting your RC model and less time waiting for the battery to charge. For most electric RC car UK enthusiasts, 6500mAh represents an excellent middle ground between weight and duration.
• 3S Cell Configuration (11.1V Nominal) — The three-cell series arrangement delivers 11.1V nominal voltage, which is the standard output voltage for thousands of RC models across cars, trucks, quadcopters and other electric RC platforms. This voltage is perfectly matched to most mid-range brushless motors and ESC systems used in the hobby.
• 30C Discharge Rating — This specification means the battery can safely deliver up to 195 amps of continuous current (6.5Ah × 30C = 195A), making it suitable for high-performance applications whilst maintaining cell longevity and safety. The 30C rating provides excellent performance without requiring the added expense and weight of ultra-high discharge-rated packs.
• XT60 Connector — The XT60 is one of the most universally adopted connectors in the RC hobby, ensuring compatibility with the vast majority of electric RC models currently in use. This connector type is rated for high currents and offers reliable connection with minimal voltage drop.
• Soft Case Construction — The protective soft case wrapping safeguards the individual cells during transport, storage, and daily use, reducing the risk of damage from impact or abrasion. This case also helps contain any potential issues and extends the overall lifespan of your battery investment.
• Practical Dimensions — Measuring 135mm in length, 44mm in width, and 34mm in height, this battery pack is compact enough to fit in a wide variety of RC platforms. The straightforward rectangular form factor makes it easy to mock-fit the battery into your model before purchase to ensure proper fitment.
• Reliable Brand Heritage — Radient is an established manufacturer in the RC battery market, known for producing quality lithium polymer packs that deliver consistent performance across hundreds of thousands of user applications worldwide.

Technical Performance

The Radient 3S LiPo 6500mAh 30C battery is engineered to deliver reliable, consistent power output across a diverse range of electric RC applications. The 11.1V nominal voltage (which rests at approximately 12.6V when fully charged and 9V when fully discharged) is the industry standard for 3-cell lithium polymer packs and provides excellent compatibility with mid-range brushless motors typically ranging from 1500KV to 5000KV, depending on your specific RC model. The 30C discharge rating represents a realistic continuous current limit of 195 amps, sufficient for aggressive driving styles, high-speed racing, and dynamic flight manoeuvres without compromising cell integrity or triggering over-current protection in quality ESC units. The 6500mAh capacity translates to meaningful runtime — most electric RC cars and trucks will achieve 15 to 25 minutes of aggressive use on a single charge, with lighter applications such as lightweight drones or foam-bodied planes potentially extending beyond 30 minutes depending on power consumption profiles. Construction quality is paramount in lithium polymer batteries; Radient cells are manufactured to consistent tolerances using proven chemistry that balances energy density, cycle life, and safety characteristics. The soft case exterior provides physical protection against puncture and abrasion, whilst the internal cell arrangement and welding standards ensure reliable power delivery throughout the battery's operational lifespan. When properly charged using a quality LiPo charger with balanced-charge capability, and when stored in accordance with manufacturer guidelines, this battery pack will maintain performance across hundreds of charge cycles, making it an economical long-term investment for the RC hobbyist.

Frequently Asked Questions

• What RC models is this 3S LiPo battery compatible with? — The Radient 3S 6500mAh 11.1V 30C XT60 is compatible with any RC car UK, RC truck, RC drone, or other electric RC model that accepts a 3S (11.1V) LiPo battery with an XT60 connector. Compatible installations must also have physical space for a pack measuring 135 x 44 x 34mm. This includes brushless RC cars, standard RC buggies, RC short-course trucks, and many ready-to-run RC platforms. Always verify your model's specifications before purchasing.
• How long will this battery last per charge? — Runtime depends entirely on your specific RC model, driving style, and power consumption. Most electric RC cars and trucks will achieve 15 to 25 minutes of moderate to aggressive driving on a single full charge of this 6500mAh pack. Lighter models or conservation-focused driving may extend beyond 30 minutes, whilst high-performance racing applications may reduce runtime to 10-15 minutes. We recommend owning multiple batteries for extended play sessions.
• Is this battery suitable for beginners? — Lithium polymer batteries require responsible handling and care, so this battery is recommended for users aged 14 and above. Beginners can certainly use this battery, but should familiarise themselves with proper LiPo charging procedures, storage practices, and safety protocols before use. We strongly recommend purchasing a quality LiPo charger with automatic cell balancing and over-charge protection.
• What charger do I need for this battery? — You will need a dedicated LiPo charger capable of charging 3S lithium polymer packs with balanced-charge functionality. The charger should support XT60 connectors or you may need an adapter. Quality LiPo chargers with built-in safety features are essential to prevent overcharging, cell damage, and potential battery failure.
• What does the 30C discharge rating mean? — The 30C rating indicates the maximum continuous current the battery can safely deliver. Calculated as 6.5Ah × 30C = 195 amps maximum continuous discharge. This rating ensures the battery can power high-performance brushless systems without damage whilst maintaining safe operating temperatures throughout aggressive use.
• How should I store this battery? — Store the Radient 3S LiPo at room temperature in a cool, dry location. For extended storage periods (longer than two weeks), store the battery at approximately 50% charge state. Never store a fully charged or fully discharged battery for extended periods. Always keep the battery in its protective soft case and consider using a fireproof LiPo storage bag for added safety.
