Key Features

• 5500mAh High Capacity — This substantial capacity ensures extended runtime during your RC driving sessions, meaning you can enjoy longer periods of uninterrupted fun before needing to recharge. Higher capacity translates directly to more minutes of play time, which is essential for competitive RC car UK owners and weekend bashers alike.
• 2S Cell Configuration (7.4V) — The 2-cell design provides the perfect balance of voltage output for a huge range of RC applications, delivering strong power delivery without requiring complex charging infrastructure. Most 2S-compatible RC models are designed to operate optimally at this voltage, ensuring you get the performance the manufacturer intended.
• 50C Discharge Rating — This impressive 50C rating means the battery can safely discharge at 275 amps (50 times its 5.5Ah capacity), delivering the punch needed for aggressive driving, racing and high-demand applications. A 50C rating is well-suited to brushless motor systems and high-performance RC setups that require strong current delivery for rapid acceleration and sustained high-speed operation.
• XT60 Connector — The XT60 is one of the most recognised and widely-used connector standards in RC hobbying, offering excellent compatibility with the vast majority of modern RC cars, buggies and trucks. This gold-plated connector ensures low-resistance power transfer and creates a secure connection that will not accidentally disconnect during use.
• Lightweight Soft Case Construction — The soft case design balances protection with weight savings, providing impact resistance during transport whilst keeping the overall battery weight minimal. This design philosophy means more of your RC model's weight budget goes towards performance rather than battery housing.
• Compact Physical Dimensions — At 127 x 43 x 21mm, this battery is designed to fit into the battery compartments of most 2S-compatible RC models without modification. The compact footprint makes it ideal for smaller-scale RC vehicles and models with limited internal space.

Technical Performance

The Radient LiPo 2S 5500mAh 7.4V 50C XT60 represents a carefully engineered balance between energy density, power output and reliability. With a 50C continuous discharge rating, this battery can deliver up to 275 amps of current safely and reliably, making it suitable for high-performance brushless motor systems commonly found in competitive RC cars UK and serious hobby-grade vehicles. The 5500mAh capacity provides genuine extended runtime compared to smaller capacity packs, particularly beneficial for running multiple qualifying rounds in RC racing or extended bashing sessions in remote locations. The 7.4V nominal voltage (approximately 8.4V when fully charged) is the standard operating voltage for 2S lithium polymer battery systems and has become the de facto standard in the mid-range RC market. The soft case construction weighs just 247 grams, incorporating modern LiPo cell technology that maximises power output relative to physical size and weight. The XT60 connector features gold-plated contacts that maintain low electrical resistance, ensuring maximum power delivery to your motor and ESC system with minimal voltage sag during high-current discharge events. Radient's quality control standards ensure consistent cell matching and balanced charging characteristics, which translates to reliable performance cycle after cycle.

Frequently Asked Questions

• What RC vehicles are compatible with the Radient 2S 5500mAh 7.4V 50C battery? — This battery is compatible with any RC model designed to accept a 2S LiPo pack with an XT60 connector. This includes numerous electric RC cars, buggies, trucks, crawlers and other RC vehicles from various manufacturers. Check your model's battery specifications to confirm it accepts 2S (7.4V) batteries with XT60 connectors. Common compatibility includes RC car UK models in the 1/10 scale range that use 2S power systems.
• Is the Radient LiPo 2S 5500mAh suitable for beginners? — This battery is recommended for RC enthusiasts aged 14 and above who have experience handling lithium polymer batteries and understand proper LiPo safety procedures. If you're new to LiPo batteries, you'll need to understand charging requirements, storage procedures, and discharge limits. LiPo batteries require a compatible balance charger and proper care to ensure safety and longevity. If you're completely new to RC, speak to our team at RC Model Shop who can guide you through battery selection and safe handling practices.
• What charger does this battery need? — The Radient LiPo 2S 5500mAh 7.4V 50C XT60 requires a dedicated LiPo balance charger capable of charging 2S batteries. The battery features balance connectors that allow a balance charger to monitor individual cell voltages during charging, ensuring safe and even charging of both cells. You cannot use a standard NiMH charger for this battery. Look for a charger rated for LiPo batteries with 2S capability and XT60 connector support.
• How long will the 5500mAh capacity last during use? — Runtime depends on your motor's power draw, which varies based on motor KV rating, gearing, driving style and terrain. As a general guide, a typical 2S brushless RC car might achieve 15-25 minutes of runtime per charge under moderate driving conditions, with sportier driving consuming the battery faster. Higher KV motors draw more current and reduce runtime, whilst lower KV motors typically extend flight time. Monitor voltage levels during use and stop driving when the battery reaches approximately 3.0V per cell (6.0V total) to preserve battery lifespan.
• What does the 50C discharge rating mean? — The 50C rating indicates the maximum continuous discharge rate as a multiple of the battery's capacity. With 5500mAh capacity, a 50C rating means this battery can safely discharge up to 275 amps continuously. Most RC applications use far less than this maximum, but the 50C rating provides headroom for high-performance driving with brushless motors, aggressive acceleration, and sustained full-throttle operation.
• How should I store this battery? — Store the Radient LiPo battery in a cool, dry location away from direct sunlight and heat sources. The ideal storage voltage for LiPo batteries is approximately 3.85V per cell (7.7V total for a 2S pack). If storing for extended periods, charge or discharge the battery to this storage voltage level. Never leave a LiPo battery fully charged for weeks on end, and never allow it to discharge completely. Use a fireproof LiPo storage bag as an additional safety precaution.
• What is the difference between this 50C battery and lower C-rating batteries? — The 50C rating allows this battery to discharge current more rapidly than lower C-rating packs. A 30C battery with the same capacity could only safely discharge 165 amps, whereas this 50C pack can deliver 275 amps. For high-performance RC vehicles that demand rapid acceleration and sustained high-speed operation, the higher C-rating provides better performance and less voltage sag under load. However, for casual driving, a lower C-rating battery would still work perfectly adequately.
