Key Features

• 3-Cell (3S) Configuration at 11.1V — This pack uses three lithium polymer cells wired in series to deliver 11.1 volts nominal output, which is the standard voltage for countless RC vehicles including brushless RC cars, RC buggies, and RC crawlers. The 3S format is one of the most widely supported battery configurations in the RC hobby, meaning compatibility with your existing equipment is highly likely.
• 1800mAh Capacity — With 1800 milliamp-hours of storage, this battery provides meaningful runtime for most RC applications. This capacity represents a practical balance, offering enough charge for extended driving sessions without adding excessive weight to your RC vehicle, which would negatively impact performance and handling.
• 30C Discharge Rating — The 30C continuous discharge rating means this pack can safely deliver 54 amps of current (1800mAh × 30C = 54A), making it suitable for moderate to high-performance RC applications. This rating provides enough power for brushless RC motors whilst maintaining safe operating temperatures, ensuring longevity and reliability during your RC sessions.
• XT60 Connector — Fitted with the robust XT60 connector, one of the most popular and reliable battery connectors in the RC hobby, this pack integrates seamlessly with the vast majority of ready-to-run and competition RC vehicles. The XT60 design ensures secure, low-resistance connections that minimise power loss and voltage drop during discharge.
• Soft Case Construction — The protective soft case helps prevent damage during transport and storage, protecting your investment whilst keeping weight to a minimum. The case design allows for flexible storage and easy fitting into tight battery compartments common in modern RC cars.
• Compact and Lightweight Design — At just 131 grams with dimensions of 105 x 36 x 17 mm, this battery is engineered for space-conscious RC builds. The compact footprint makes it ideal for vehicles with restrictive battery bays, and the light weight helps maintain optimal weight distribution and performance in your RC model.
• Age Recommendation 14+ — This product is recommended for users aged 14 and above, reflecting the responsibility required for safe lithium polymer battery handling, charging, and storage. LiPo batteries demand proper care and attention, and this age recommendation ensures users understand the importance of safe practices.

Technical Performance

The Radient LiPo 3S 1800mAh 11.1V 30C XT60 represents solid engineering in a compact package. The three-cell lithium polymer configuration delivers the 11.1-volt nominal output that has become the industry standard for mid-range RC vehicles, from RC car UK platforms to aerial RC models. The 1800mAh capacity sits at approximately 19.98 watt-hours of stored energy, making this a genuinely useful power source for hobby-grade equipment. The 30C discharge rating is conservative enough to ensure safe operation across a broad range of motor sizes and ESC configurations, yet aggressive enough to support modern brushless RC motors with respectable KV ratings. Build quality from Radient is consistently reliable, with proper cell matching, internal resistance management, and connector soldering that ensures this battery will provide years of dependable service when handled correctly. The soft case offers adequate protection against physical damage whilst remaining flexible enough to fit into the battery compartments of most commercial RC vehicles. Temperature performance is typical for quality lithium polymer cells—the pack will deliver full power under moderate ambient temperatures, though performance may be slightly reduced in cold conditions. Proper charging with a quality LiPo-compatible charger is essential; we recommend using a charger with cell-balancing capability to maintain optimal cell health and maximise cycle life. With appropriate care and storage in a cool, dry location, this Radient pack should provide hundreds of charge cycles of reliable performance.

Frequently Asked Questions

• Is the Radient 3S 1800mAh 11.1V 30C XT60 suitable for beginners? — Yes, this battery is suitable for beginner RC hobbyists aged 14 and above. However, LiPo batteries do require responsible handling and charging practices. Beginners should familiarise themselves with proper LiPo safety procedures, including using a dedicated LiPo charger, avoiding over-discharge, and storing the battery in a fireproof container. The 30C rating is conservative enough that it won't deliver excessive power that could overwhelm a beginner's RC vehicle control.
• What RC vehicles is this battery compatible with? — The Radient LiPo 3S 1800mAh 11.1V is compatible with any RC vehicle with an XT60 connector socket that accepts 3S batteries. This includes many popular brushless RC cars, RC buggies, RC crawlers, RC trucks, and aerial RC models. Before purchasing, verify that your vehicle specifications list 3S LiPo compatibility and XT60 connectors.
• How long will this battery last per charge? — Runtime depends entirely on your RC vehicle's motor, ESC, weight, and driving style. As a general rule, a 1800mAh battery in a typical 1/10-scale RC car will provide 15-25 minutes of active driving before requiring recharge. Racing and high-throttle driving depletes the battery faster than casual use. Refer to your vehicle's manual for specific runtime estimates.
• How do I charge the Radient LiPo 3S 1800mAh 11.1V 30C battery? — You must use a dedicated LiPo-compatible battery charger. Set the charger to 3S LiPo mode and charge at 1800mA (1C rate) for safest operation, though your charger may support faster charging depending on its capabilities. Never attempt to charge this battery with a standard NiMH charger—LiPo batteries require dedicated charging systems. The XT60 connector plugs directly into your charger's balance connector or main discharge port depending on your charger design.
• What is the difference between this 30C Radient pack and higher C-rated alternatives? — The 30C discharge rating limits the maximum safe current draw to 54 amps. Higher C-rated packs (such as 50C or 100C) can safely deliver more current, making them better for high-performance racing motors or large-scale RC vehicles. The 30C Radient pack is ideal for moderate performance applications and everyday RC use, offering excellent value without overkill capacity. If your vehicle requires sustained currents above 54 amps, upgrade to a higher C-rating pack.
• Is this battery suitable for RC racing? — The Radient LiPo 3S 1800mAh 11.1V 30C can support competitive RC racing applications, depending on your vehicle class and motor specification. The 30C rating provides adequate power for most competition-grade brushless RC motors in 1/10 and 1/8-scale racing vehicles. For high-level racing where peak performance is critical, some competitors prefer higher C-rated packs to reduce voltage sag under peak load, but this Radient pack is entirely capable in racing scenarios.
• How should I store this battery? — Store the Radient battery in a cool, dry location between uses. Ideally, store the battery in a dedicated fireproof LiPo storage bag or container. Before extended storage, charge the battery to approximately 3.85 volts per cell (11.55 volts total) rather than leaving it fully charged or fully depleted. Check the battery monthly during long-term storage and rebalance if necessary. Avoid storing near heat sources or in direct sunlight.
• What makes the XT60 connector better than other battery connectors? — The XT60 connector is the RC hobby standard for batteries in this power range. Its robust design features gold-plated contacts that resist oxidation, secure bayonet-lock mating that prevents accidental disconnection, and low electrical resistance that minimises power loss. XT60 connectors are widely available, reliable, and compatible with the vast majority of RC equipment in the UK market.
