• Soft Case Protection — The integrated soft case protects your battery from physical damage during transport and storage, whilst remaining lightweight to avoid adding unnecessary weight to your RC model, preserving the performance characteristics you've tuned your vehicle for.
• Compact Dimensions — At just 125mm long, 44mm wide, and 28mm high, this battery pack is engineered to fit within the battery trays of most modern RC vehicles, offering a competitive advantage in weight distribution and chassis balance without requiring major model modifications.
• Lightweight Design — Weighing only 0.29kg (approximately 10.2oz), this battery contributes minimal mass to your RC setup, allowing you to maintain optimal weight distribution and handling characteristics across your vehicle.

Technical Performance

The Radient LiPo 3S 5500mAh 11.1V 30C battery pack represents a carefully engineered balance between capacity, discharge performance, and physical constraints. The 30C continuous discharge rating (with potential burst ratings higher) makes this battery suitable for electric RC cars, buggies, crawlers, and trucks that demand reliable power delivery under sustained acceleration and cornering loads. The 11.1V nominal voltage corresponds to the industry-standard 3S (three-cell) configuration, where each cell contributes approximately 3.7V at nominal charge. This voltage is perfectly matched to modern brushless motor systems and electronic speed controllers (ESCs) designed for 3S operation, ensuring optimal motor performance, maximum efficiency, and safe ESC operation. The 5500mAh capacity is substantial enough to provide 20-40 minutes of runtime depending on driving style and motor KV rating, making extended play sessions practical without requiring multiple battery packs. LiPo technology offers superior energy density compared to older battery chemistries, meaning you get more power per kilogramme of weight, critical for maintaining the performance envelope of your RC vehicle. The soft case construction utilises durable polymer materials designed to resist puncture and abrasion, whilst the precision-moulded shape ensures the battery sits securely in standard battery trays. The XT60 connector uses gold-plated contacts to minimise resistance and heat generation during discharge, with robust mechanical design to withstand repeated connection and disconnection cycles without degradation. This battery pack is perfect for RC car UK applications where reliability and performance are paramount, from casual weekend bashing to competitive racing events.

Frequently Asked Questions

• What vehicles is the Radient 3S 5500mAh LiPo battery suitable for? — This battery is compatible with any RC car, buggy, truck, or crawler that uses a 3S (11.1V) LiPo battery with XT60 connector. Common applications include 1/10 scale brushless RC buggies, monster trucks, short-course trucks, and crawlers. Always check your vehicle's battery compartment dimensions (125mm × 44mm × 28mm) and verify that your ESC is rated for 3S operation before purchase to ensure a perfect fit and safe operation.
• How long will this battery last per charge? — Runtime varies based on driving style, motor KV rating, and terrain. Casual bashers typically achieve 25-40 minutes of runtime, whilst racing drivers pushing peak performance may see 15-25 minutes per charge. The 5500mAh capacity ensures you'll enjoy extended play sessions compared to smaller capacity packs, making it an excellent choice for weekend sessions where multiple short charges between runs becomes impractical.
• Is this battery suitable for beginners? — Whilst the battery itself is straightforward to use, LiPo batteries require proper handling, storage, and charging equipment. The recommended age of 14+ reflects the maturity needed to follow essential safety protocols including using a dedicated LiPo charger, monitoring cell voltage, and safely storing the battery. Beginners should ensure they have appropriate charging equipment and understand LiPo safety requirements before operating this battery pack.
• What charger do I need for this battery? — You'll require a multi-cell LiPo charger capable of charging 3S batteries. Most modern RC chargers support 3S charging at various amperage rates. The standard charging rate is 0.5C to 1C (2.75A to 5.5A), meaning a 5A charger will fully recharge your battery in approximately one hour at 1C rate. Never use standard NiMH chargers, as they will damage the battery or create a fire hazard.
• What is the difference between 30C and higher C-ratings? — The 30C rating indicates continuous discharge current capacity (5500mAh × 30C = 165A continuous). Higher C-rated batteries support greater sustained current draw, beneficial for high-powered motors and aggressive racing. The 30C rating suits most standard brushless RC applications; however, extreme high-performance setups may benefit from 50C+ rated batteries. The Radient 30C rating provides excellent balance between performance, cost, and reliability for typical RC car UK use cases.
• How should I store this battery? — Store the Radient LiPo battery in a cool, dry location away from direct sunlight and extreme temperatures. For long-term storage (more than two weeks), charge the battery to approximately 50% state of charge and store in a fireproof container or LiPo safe bag. Avoid storing fully charged or fully discharged batteries, as this accelerates cell degradation and reduces lifespan.
• Is the XT60 connector universal? — The XT60 connector is the industry standard for modern RC batteries and ESCs in the UK and worldwide. The vast majority of contemporary RC equipment uses XT60 connectors, ensuring universal compatibility. However, always verify your vehicle's ESC features XT60 input before purchasing, as older models may use alternative connectors such as Deans, EC3, or XT90.
• What does the soft case protect against? — The integrated soft case provides protection from physical impacts, abrasion, and minor puncture during transport, storage, and field use. The protective case helps prevent the battery from contacting metal objects that could cause short circuits, and provides cushioning against drops or impacts that might otherwise damage the battery cells, thereby extending battery lifespan and ensuring safe operation.
