Key Features

• 3S LiPo Chemistry (11.1V nominal) — Three-cell lithium polymer construction delivers the 11.1V nominal voltage that powers countless RC models across the UK, ensuring compatibility with a massive range of RC cars, trucks, buggies, helicopters and other electric RC platforms. Three-cell packs represent the most popular voltage in the RC hobby, balancing power output with cell count.
• 3250mAh Capacity — The 3250 milliamp-hour capacity provides generous runtime for extended RC sessions without requiring constant recharging. This mid-range capacity is large enough for meaningful flight or drive times yet compact enough to fit into most RC model battery bays designed for 3S power.
• 30C Continuous Discharge Rating — The 30C rating means this battery can safely deliver 97.5 amps of continuous current (3250mAh × 30C = 97.5A), making it suitable for high-throttle applications including brushless RC motors, electric RC helicopters, racing quads and fast RC buggies. This discharge rating ensures the battery can keep pace with modern brushless systems without voltage sag or thermal issues.
• XT60 Connector — The XT60 connector is the industry standard for RC batteries in this power class, offering secure gold-plated contacts that resist corrosion and ensure reliable power delivery. XT60 connectors are widely used across RC car UK platforms, RC helicopters, quadcopters and other RC vehicles, meaning you'll have no trouble finding compatible chargers, balance leads and ESC connections.
• Soft Case Protection — Unlike loose cells, this battery arrives in a protective soft case that safeguards the delicate LiPo cells from punctures, impacts and environmental hazards during transport and storage. The case also helps with organisation in your RC workshop or hobby bag.
• Compact Form Factor — Measuring just 135mm long, 44mm wide and 21mm tall, this battery pack is slim and streamlined enough to fit into restricted battery compartments whilst still delivering substantial capacity. The compact dimensions make it ideal for RC models where space is at a premium.
• Lightweight Design — At 0.28kg (0.61 lbs), this battery adds minimal weight to your RC model, helping preserve acceleration, agility and overall flight or drive dynamics. Lightweight batteries are especially important in RC helicopters, racing quadcopters and lightweight RC buggies where every gram affects performance.
• Age Recommendation 14+ — Suitable for teenagers and adults, this battery is appropriate for users with basic understanding of LiPo safety protocols, charging procedures and proper storage techniques. Young users should always use this battery under adult supervision.

Technical Performance

The Radient LiPo 3S 3250mAh 11.1V 30C XT60 represents solid mid-range engineering built to Radient's recognised quality standards. The 30C discharge rating provides excellent performance headroom, allowing the battery to maintain stable voltage under demanding loads from brushless RC motors, racing ESCs and high-performance radio control systems. At nominal 3S voltage (11.1V), this battery suits a vast array of RC applications including 1/10-scale brushless RC cars, 1/8-scale RC buggies and trucks, FPV racing quadcopters, and electric RC helicopters ranging from micro to mid-size platforms. The 3250mAh capacity strikes an intelligent balance between providing meaningful runtime — typically 8-15 minutes of aggressive driving or flying depending on the specific RC model and power demand — whilst maintaining a compact, lightweight footprint. The XT60 connector features soldered joints designed to withstand repeated connecting and disconnecting cycles, crucial for hobbyists who regularly swap batteries between multiple RC vehicles. Radient's cell matching and balancing ensures all three cells maintain nearly identical voltage and capacity, reducing balancing charge times and extending overall battery lifespan. The soft case uses durable material that resists abrasion whilst remaining flexible enough to conform to odd-shaped battery bays in modern RC chassis designs.

Frequently Asked Questions

• Is the Radient 3250mAh 11.1V 30C LiPo suitable for my RC car? — This battery is compatible with any electric RC model designed for 3S LiPo batteries (11.1V nominal) that features an XT60 connector and can accommodate a battery pack measuring 135 x 44 x 21mm. Many popular RC car brands including Traxxas, ARRMA, Losi and FTX offer models that accept 3S packs with XT60 connectors. Check your RC vehicle's manual or contact our team for specific compatibility confirmation.
• What is the runtime I should expect from this 3250mAh battery? — Runtime depends entirely on your specific RC model and driving style. High-speed RC cars with powerful brushless motors will deplete the battery faster (typically 8-12 minutes of continuous throttle), whilst lighter RC models or more conservative driving will extend runtime to 15-20 minutes. Racing applications consume battery capacity quickly, whilst casual bashing and slow-speed crawling deliver longer runtimes per charge cycle.
• Can I use this battery with my brushless RC motor? — Yes, absolutely. The 30C discharge rating provides excellent performance with brushless motors commonly found in 1/10-scale and 1/8-scale RC cars. Most brushless systems draw well within the 97.5A continuous discharge capability of this pack. Always ensure your ESC (electronic speed controller) supports 3S LiPo voltage and is rated for the amperage your motor demands.
• How do I charge this Radient LiPo safely? — Use only a LiPo-compatible charger set to 3-cell (3S) mode. Charge at 1C rate (3.25A) for safe charging, though higher rates are possible if your charger supports them. Never use NiMH or NiCd chargers. Always balance-charge using the JST-XH balance connector if available on your charger. Charge in a safe location away from flammable materials and never leave charging batteries unattended. Radient batteries include cell balancing plugs for convenient balance-charging.
• What does the 30C rating mean and why does it matter? — The 30C rating indicates the safe continuous discharge rate expressed as a multiple of the battery's capacity. For a 3250mAh battery, 30C means maximum safe continuous current of 97.5 amps (3.25Ah × 30 = 97.5A). This high discharge rating allows the battery to supply power to demanding brushless motors and racing ESCs without voltage sag or overheating. Higher C ratings deliver more consistent performance under load.
• Is the XT60 connector universal across RC brands? — The XT60 connector is industry-standard across most RC brands and platforms in this power range. However, some manufacturers use alternative connectors like EC5, Deans or XT90. Your RC model must have an XT60 female connector, or you'll need an XT60-to-your-connector adapter cable. RC Model Shop stocks adapters if needed.
• How long will this battery last before I need to replace it? — With proper care including storage at 50% charge, cool dry storage conditions, and avoiding over-discharge or over-charge, a Radient LiPo can provide 200-300 charge cycles before capacity begins to noticeably diminish. Aggressive use and poor storage will reduce lifespan significantly. Monitor capacity and retire batteries that no longer hold charge reliably.
• What is the storage voltage for LiPo batteries? — Lithium polymer batteries should be stored at partial charge (approximately 3.8V per cell, or about 11.4V total for a 3S pack). Never store fully charged or fully discharged. Before long-term storage, allow the battery to rest for several hours after use, then charge or discharge as needed to reach storage voltage. Store in a cool, dry location away from heat sources.
