Key Features

• 2S LiPo Chemistry with 7.4V Output — This battery uses two lithium polymer cells configured in series to deliver a nominal voltage of 7.4V, which is the standard power requirement for countless RC models available in the UK market today. The 2S configuration strikes an excellent balance between voltage, weight and cost, making it one of the most popular battery formats for mid-range RC vehicles and aircraft.
• 1350mAh Capacity for Extended Runtime — With 1350 milliamp-hours of stored energy, this battery provides sufficient capacity to power most RC models for a decent session length. This capacity is neither too large nor too small, offering practical run times whilst maintaining the compact, lightweight profile that performance-oriented RC builders demand.
• 30C Continuous Discharge Rating — The 30C rating means this battery can safely discharge at 30 times its capacity per hour, delivering up to 40.5 amps of continuous current. This discharge rating is perfectly suited for electric RC cars, buggies, and lightweight aircraft, ensuring responsive throttle control and consistent power delivery throughout your flight or drive.
• EC3 Connector for Secure Power Transfer — The gold-plated EC3 connector provides a secure, reliable electrical connection that minimises resistance and heat generation during operation. EC3 connectors are widely adopted across the RC industry and offer superior contact integrity compared to older connector designs, giving you confidence in every flight or drive session.
• Compact 79g Weight Package — Weighing just 79 grams, this battery adds minimal mass to your RC model, allowing for better handling characteristics, improved acceleration and climbing ability for crawlers, and extended flight times for aircraft. The light weight is crucial for maintaining the performance envelope of your RC build without requiring significant rebalancing or adjustment.
• Generous Physical Dimensions of 72 x 36 x 15mm — The carefully optimised dimensions ensure this battery fits into most standard battery compartments on RC cars, buggies and aircraft designed for 2S power. The relatively flat profile (just 15mm height) makes it straightforward to fit into chassis designs with limited vertical space.
• Protective Soft Case Included — This battery arrives protected in a durable soft case, providing cushioning and protection during transport, storage and handling. The case helps prevent accidental damage to the battery cells and connector, extending the service life of your investment.
• Manufactured by Trusted Radient Brand — Radient is an established manufacturer of RC batteries and power products, with a reputation for consistent quality and reliable performance. Choosing Radient gives you access to batteries designed and tested to deliver predictable, stable power output every single time you charge and fly or drive.

Technical Performance

This Radient LiPo battery exemplifies modern lithium polymer cell technology, engineered specifically for the demands of contemporary RC models. The 2S configuration, producing 7.4V nominal output with a fully charged voltage of 8.4V, is the industry standard for a vast range of electric RC cars, buggies, crawlers and quadcopter aircraft. The 1350mAh capacity delivers approximately 10 watt-hours of energy storage, sufficient for most recreational flying sessions lasting 8-15 minutes depending on throttle usage and aircraft weight, or for longer RC car driving sessions when sensible power management is employed. The 30C discharge rating represents a peak current capacity of 40.5 amps, which translates to rapid throttle response and consistent power delivery during aggressive acceleration or climbing manoeuvres. Unlike cheaper low-C-rated batteries that exhibit voltage sag and performance degradation under load, this 30C pack maintains voltage stability and output consistency throughout its discharge cycle, ensuring your RC model performs predictably from full charge through to the conclusion of your driving or flying session. The gold-plated EC3 connector minimises electrical resistance at the connection point, reducing heat generation and ensuring maximum efficiency of power transfer from the battery to your speed controller. The soft polymer case construction protects the internal cells from mechanical damage whilst allowing adequate ventilation during charging and operation, essential for maintaining long-term battery health and safety. Built to the specifications required by serious RC enthusiasts across the UK, this battery represents excellent engineering value and dependable performance that will serve you well across multiple seasons of recreational and competitive RC activities.

Frequently Asked Questions

• Is the Radient LiPo 2S 1350mAh battery suitable for RC car beginners in the UK? — Yes, this battery is an excellent choice for newcomers to RC hobby. The 2S 7.4V voltage is the standard power source for entry-level to intermediate RC cars and buggies, and the 1350mAh capacity provides adequate runtime for learning sessions. However, you must ensure your speed controller (ESC) is rated for 2S LiPo batteries, and you should familiarise yourself with proper LiPo charging, storage and safety procedures before use. Consider purchasing a dedicated LiPo charger and balance charger for safe operation.
• What RC models will this 2S LiPo battery power? — This battery is compatible with any RC model designed to accept 2S LiPo batteries with an EC3 connector, including electric RC cars, buggies, crawlers, rock crawlers, trail trucks, and lightweight RC aircraft such as quadcopters and fixed-wing planes. Always verify your model's battery specification before purchase to ensure compatibility with this 7.4V pack.
• How long will the 1350mAh capacity provide runtime? — Runtime depends entirely on your RC model's weight, motor power, throttle usage and the specific load drawing current from the battery. Light aircraft and small RC cars might achieve 10-15 minutes of moderate flying or driving, whilst heavier models or aggressive full-throttle usage will reduce this significantly. Conservative power management extends runtime considerably.
• What is the advantage of the 30C discharge rating on this battery? — The 30C rating means this battery can safely deliver high current output without excessive voltage sag or performance degradation. This translates to responsive throttle control, better acceleration, improved climbing ability for crawlers, and more stable flight performance compared to lower-C-rated batteries of identical capacity. Higher C ratings are essential for high-performance RC applications.
• Is the EC3 connector widely used in the RC hobby? — Yes, the EC3 connector is one of the most popular battery connectors in modern RC applications, particularly for mid-range electric RC vehicles and aircraft. It offers superior contact reliability and current-carrying capacity compared to older XT connector designs. Check that your speed controller features an EC3 female socket to ensure proper compatibility before purchase.
• How should I store and care for this LiPo battery? — Store your LiPo battery in a cool, dry location away from direct sunlight at approximately 50% state of charge, ideally in a dedicated LiPo storage bag for safety. Never leave the battery fully charged or fully depleted for extended periods. Always inspect the battery for physical damage, puffing or swelling before each use, and discontinue use immediately if any damage is observed. Charge using only a dedicated LiPo-compatible charger with balance charging capability.
