Key Features

• 3S LiPo Chemistry with 11.1V Nominal Voltage — Three lithium polymer cells in series deliver 11.1V of nominal voltage, which is the industry-standard power delivery for countless RC electric motors, electronic speed controllers (ESCs) and radio systems. This voltage is perfectly matched to brushless RC motors in the mid-range KV ratings, offering the sweet spot between torque and top speed for most recreational and competitive RC applications.
• 3250mAh Capacity for Extended Runtime — The 3250 milliamp-hour capacity provides a practical amount of usable energy, giving you between 10 to 25 minutes of continuous running time depending on your model's power draw and driving style. This capacity is large enough to enjoy extended play sessions without constant recharging, yet compact enough to fit into most RC vehicle chassis designed for 3S packs.
• 30C Continuous Discharge Rating — The 30C rating means this battery can safely discharge at 30 times its capacity continuously, equating to 97.5 amps maximum continuous current output. This performance level is suitable for most electric RC cars, buggies, and trucks, providing responsive acceleration and maintaining voltage stability even under demanding acceleration and cornering loads.
• Deans (HCT) Connector Standard — The HCT (Heavy Duty Connector) variant of the Deans connector is one of the most widely used battery connectors in the RC hobby. This universal fitting ensures compatibility with the vast majority of ready to run RC models, ESCs, and battery chargers available in the UK market, eliminating the need for expensive adapter cables.
• Compact Dimensions for Space-Constrained Builds — Measuring just 135mm in length, 44mm in width, and 21mm in height, this battery pack is engineered for tight battery bays. The compact footprint allows for flexible placement within your RC chassis, helping maintain optimal weight distribution and centre of gravity without compromising on capacity or performance.
• Soft Case Protection — The battery arrives in a protective soft case that shields the cells from physical damage during storage and transport. This padding helps prevent punctures and short circuits, extending the life of your investment and ensuring safe handling between charging sessions and track days.
• Age Recommendation 14+ — Designed for responsible operators aged 14 and above, this battery reflects the maturity and understanding required to handle LiPo cells safely. Proper charging, storage, and handling of lithium polymer batteries demands care and attention to prevent thermal runaway or damage.

Technical Performance

The Radient LiPo 3S 3250mAh 11.1V 30C pack delivers robust electrical performance across a broad spectrum of RC applications. The 30C continuous discharge rating translates to a maximum safe current draw of approximately 97.5 amps, which positions this battery firmly in the performance category for most electric RC vehicles. The 11.1V nominal voltage is the perfect match for brushless RC motors with mid-range KV ratings (typically between 2000KV and 4500KV), enabling smooth power curves without voltage sag that would compromise handling or acceleration responsiveness. Build quality is evident in the professional-grade cell construction, with Radient's reputation for reliable energy storage backed by consistent performance in competitive and recreational settings. The soft case provides essential protection against physical damage whilst the compact dimensions — 135 x 44 x 21 millimetres — ensure compatibility with modern RC chassis designs. The Deans HCT connector is soldered using industry-standard techniques, providing low-resistance connections that maximise power transfer efficiency from the cells to your speed controller and motor system. Whether you're running a 2WD buggy, a 4WD short course truck, or a dedicated carpet racer, this battery integrates seamlessly with established RC infrastructure available throughout the UK.

Frequently Asked Questions

• Which RC models is the Radient 3S 3250mAh 11.1V battery compatible with? — This battery is compatible with any RC model that accepts 3S 11.1V LiPo packs fitted with a Deans (HCT) connector. This includes countless ready to run RC cars, buggies, trucks, and crawlers available in the UK market. The battery will also work with aftermarket installations and hobby-grade conversions where space permits the 135 x 44 x 21mm dimensions. Check your RC model's manual or contact the manufacturer to confirm compatibility before purchase.
• Is the Radient 3S 3250mAh suitable for RC beginners? — Yes, this battery is ideal for beginners aged 14 and upwards who have access to proper LiPo charging equipment and understand safe battery handling practices. The 3250mAh capacity provides decent runtime for learning driving techniques, whilst the 30C discharge rating is sufficient for entry-level to intermediate-level electric RC vehicles. However, you must invest in a proper LiPo-compatible charger and understand the risks associated with lithium polymer batteries before operating this pack.
• What charger do I need for the Radient 3S 3250mAh battery? — You will need a LiPo-compatible battery charger capable of charging 3S packs. The charger must feature cell balancing to ensure each of the three cells charges to the same voltage, typically 4.2V per cell for a full charge of 12.6V total. Many modern RC chargers support 3S packs, and the Deans connector works with standard charging leads. Always follow the charger manufacturer's instructions and never leave a charging LiPo battery unattended.
• How long will the Radient 3250mAh battery last per charge? — Runtime depends on your RC model's power consumption, which is determined by motor size, KV rating, ESC efficiency, and your driving style. Typically, expect between 10 to 25 minutes of continuous running time. High-speed racing and aggressive acceleration will deplete the battery faster than casual bashing or crawling. The 3250mAh capacity is best suited to models with moderate power draws; high-powered 4WD trucks or stadium trucks may experience notably shorter runtimes.
• Is the Deans (HCT) connector standard across most RC batteries? — Yes, the Deans connector, particularly the HCT (Heavy Duty) variant, is one of the most widely adopted battery connectors in the hobby-grade RC industry throughout the UK and internationally. This means you can easily source compatible ESCs, charging leads, and battery connectors from multiple manufacturers without requiring adapters or soldering work.
• Can I use this battery in cold weather or wet conditions? — LiPo batteries perform best at moderate temperatures between 10°C and 30°C. Cold weather reduces battery capacity and voltage output, whilst overheating can damage cells permanently. Avoid exposing this battery to rain, mud, or water — whilst many modern ESCs are waterproof, the battery pack itself is not designed for submersion. Always store the battery in a cool, dry place and allow it to reach room temperature before charging after cold-weather use.
• What makes the 30C discharge rating important? — The 30C continuous discharge rating indicates the maximum safe current the battery can deliver without overheating or damaging the cells. This 30C capability (approximately 97.5 amps at 3250mAh) is suitable for most recreational and intermediate-level electric RC vehicles, ensuring responsive acceleration and stable voltage delivery during demanding driving. Higher-performance racing applications may require higher C-rating batteries, whilst casual bashers might find this rating more than adequate.
