Key Features

• 2S LiPo Cell Configuration — The dual-cell design delivers a nominal voltage of 7.4V, which provides adequate power for a wide range of brushed and brushless RC systems, motors and ESCs commonly found in UK RC hobby setups. This voltage is a proven standard across thousands of RC vehicles and accessories.
• 3250mAh High Capacity — The substantial 3250 milliamp-hour capacity ensures extended runtime during driving sessions, reducing the need for frequent recharging and allowing you to enjoy longer periods of uninterrupted RC fun on the track, trail or field.
• 50C Discharge Rating — This impressive C-rating means the battery can safely deliver extremely high discharge currents, making it suitable for high-performance applications including competitive RC racing, aggressive bashing, and vehicles equipped with powerful brushless motors that demand sustained power delivery.
• Deans (HCT) Connector — The Deans T-style connector is one of the most popular connector types used throughout the RC hobby in the UK and worldwide. This connector type provides a secure, reliable connection with excellent electrical contact and minimal voltage drop, ensuring efficient power transfer from battery to vehicle.
• Compact 15mm Slim Profile — The ultra-thin 15mm height allows this battery to fit into chassis designs with tight battery compartments or limited vertical clearance, making it compatible with a broader range of RC vehicles than bulkier battery options.
• Lightweight 183g Construction — At just 183 grams, this LiPo pack minimises additional weight, helping to maintain your RC vehicle's optimal balance, acceleration response, and handling dynamics compared to heavier battery alternatives.
• Protective Soft Case — The battery arrives in a protective soft case that shields the cells from physical damage during storage, transport and use, extending the lifespan of your investment and maintaining safety standards.
• Precise Dimensions — Measuring 137mm in length, 43mm in width and 15mm in height, the compact rectangular form factor fits into most battery trays designed for 2S packs, though Radient recommends confirming your vehicle's specific tray dimensions and connector compatibility before purchase.

Technical Performance

The Radient LiPo 2S 3250mAh 7.4V 50C battery pack represents a well-engineered balance of capacity, discharge capability and physical form factor. The 7.4V nominal output (8.4V fresh from the charger) sits comfortably within the input specification ranges of virtually all modern RC ESCs, brushless speed controllers, and motor systems designed for 2S operation. The 50C discharge rating is particularly noteworthy, providing a maximum continuous discharge capability of approximately 162.5 amps under ideal conditions — sufficient to power even demanding brushless motor setups rated for serious performance applications. The 3250mAh capacity, combined with this high C-rating, creates a pack that excels in both high-current racing scenarios and extended-duration recreational bashing sessions. Construction quality is evident in the professional-grade soft case, which includes internal cell management to prevent swelling and damage. The Deans connector offers superior contact integrity and minimal internal resistance compared to older connector standards, ensuring maximum voltage delivery to your RC vehicle's electronics. Weight distribution is optimised for the 137 x 43 x 15mm envelope, making this pack suitable for installation in vehicles ranging from small race buggies to larger RC trucks. UK RC hobbyists will appreciate the reliability and consistency Radient packs deliver, with no calibration or configuration required — simply install, charge with an appropriate 2S LiPo charger, and begin running. Battery maintenance is straightforward: store at safe resting voltage (around 3.7V per cell) when not in use for extended periods, and always use a proper LiPo charger equipped with cell-balancing functionality to maximise lifespan and safety.

Frequently Asked Questions

• Is the Radient 2S 3250mAh LiPo battery suitable for beginners in RC hobby? — Yes, this battery is appropriate for users aged 14 and above as specified by the manufacturer age recommendation. It is a standard 2S LiPo pack with proven compatibility across thousands of RC vehicles, making it an excellent choice for newcomers to RC cars UK who have already purchased a compatible vehicle. However, beginners should familiarise themselves with proper LiPo charging and storage procedures, as lithium polymer batteries require more care than older battery chemistries.
• What is the runtime I can expect from the 3250mAh capacity? — Runtime varies significantly depending on your specific vehicle, motor setup, driving style and throttle usage. As a general guideline, a 3250mAh capacity in an efficient lightweight RC buggy might deliver 25-40 minutes of runtime, whilst higher-powered vehicles or those with larger motors may see 15-25 minutes per charge. We recommend purchasing multiple batteries to maximise your driving time during RC sessions.
• What charger do I need for this Radient battery? — This is a 2S LiPo pack requiring a dedicated LiPo battery charger with 2S capability and cell-balancing functionality. The charger must output appropriate current (typically 1-3C rate, or 3.25-9.75 amps for this 3250mAh pack). Many popular chargers sold at RC Model Shop support 2S LiPo charging, including multifunction chargers compatible with various battery types. Always verify your charger supports 7.4V/2S LiPo packs before purchasing.
• Is this battery compatible with my RC vehicle? — This battery features the Deans (HCT) T-style connector, which is extremely common in the RC hobby. Before purchasing, you must verify that your vehicle's ESC accepts 2S LiPo packs (7.4V nominal) and features a compatible Deans connector or an adapter harness. We recommend contacting our team at RC Model Shop on 01543 577278 to confirm compatibility with your specific model.
• What is the difference between 50C and other C-ratings? — The C-rating indicates the maximum safe discharge current relative to capacity. A 50C rating on this 3250mAh pack allows a maximum continuous discharge of approximately 162.5 amps, whilst a 25C pack of the same capacity would be limited to around 81 amps. Higher C-ratings enable more powerful vehicle performance and rapid acceleration, making 50C packs ideal for competitive racing or high-performance brushless setups, whilst lower C-rating packs may be more economical for casual recreational use.
• How should I store this LiPo battery? — LiPo batteries should be stored in a cool, dry location away from direct sunlight and heat sources. For storage periods exceeding one week, charge or discharge the battery to approximately 3.7V per cell (7.4V total for this 2S pack) — sometimes called storage voltage — which minimises stress on the cells. Store in a fireproof LiPo storage bag as a safety precaution. Always inspect for swelling, damage or puffing before each use, and discontinue use immediately if any damage is observed.
• What does the 15mm slim profile mean for my RC vehicle? — The 15mm height is considerably thinner than many 2S LiPo packs, allowing this battery to fit into vehicles with restricted battery compartment height. This is particularly valuable for low-slung chassis designs, scale trucks with limited interior space, or buggies where ground clearance is a design priority. Always verify your vehicle's battery tray dimensions match the 137 x 43mm footprint and have at least 15mm clearance before purchasing.
