This soft-case LiPo pack represents excellent value for money at just £19.94, offering the perfect balance between capacity and physical size. The 1800mAh capacity provides adequate runtime for most recreational flying and driving applications, whilst the compact dimensions of 105 x 36 x 18mm mean it fits neatly into battery bays designed for standard 3S configurations. Radient batteries are recognised for their quality construction and reliable performance, making this pack a trusted choice for RC car UK owners and international enthusiasts alike.

The 11.1V nominal voltage is the standard specification for 3-cell lithium polymer batteries, delivering the power characteristics that RC motors are designed to work with. Whether you're running a ready to run RC vehicle, upgrading an existing setup, or building a custom RC project from scratch, this Radient battery provides the energy you need to keep your hobby running smoothly.

Key Features

• 3S Configuration (11.1V Nominal Voltage) — Three lithium polymer cells in series provide the standard 11.1V output that RC motors expect, ensuring optimal performance and preventing damage from over-voltage or under-voltage conditions. This voltage is the industry standard for countless RC applications.
• 1800mAh Capacity — The 1800mAh energy capacity provides sufficient runtime for extended play sessions without excessive weight, making this battery ideal for models where compact size and lightweight performance are prioritised over maximum endurance.
• 30C Continuous Discharge Rating — The 30C discharge rating means this battery can safely deliver 54 amps of continuous current (1800mAh × 30C), providing plenty of power for most hobby-grade RC vehicles including electric RC cars, RC buggies, and RC crawlers without thermal stress or reduced lifespan.
• EC3 Connector — The EC3 connector is widely used across the RC hobby industry and provides secure, reliable power connections with low resistance, ensuring minimal voltage drop and maximum efficiency from battery to motor.
• Soft Case Construction — The protective soft case guards the cells from physical damage during transport and storage, whilst remaining flexible enough to fit snugly into tight battery compartments without damage to surrounding components.
• Compact Physical Dimensions — At just 105 x 36 x 18mm, this battery pack is small enough to fit into battery bays on compact RC vehicles, trail trucks, and smaller-scale models where space is at a premium, yet substantial enough to deliver meaningful power output.
• Lightweight Design — With a shipping weight of 160 grams, this battery adds minimal mass to your RC vehicle, helping to maintain responsiveness and efficiency whilst still providing adequate power for diverse driving conditions.

Technical Performance

The Radient LiPo 3S 1800mAh 11.1V 30C pack delivers reliable, consistent performance across a wide range of RC applications. The 30C discharge rating represents a balance between power delivery and battery longevity, making it suitable for recreational bashing, park flying, and moderate-speed driving without the extreme demands of competitive racing. The three-cell configuration produces the standard 11.1V output that RC electric motors are engineered to accept, ensuring you get the performance characteristics your equipment was designed for. The EC3 connector provides low-resistance connections that minimise voltage drop, meaning more of the battery's energy reaches your motor rather than being wasted as heat in the connector itself. The soft case provides essential protection during the inevitable bumps and impacts of RC operation, helping to prevent punctures and cell damage that could lead to battery failure or safety hazards. The compact size makes this battery particularly suitable for smaller RC vehicles, trail crawlers, and compact electric RC cars where larger battery packs simply won't fit. Whether you're operating in the UK or internationally, this Radient pack represents genuine quality construction backed by a manufacturer recognised for producing reliable LiPo batteries for the RC hobby sector.

Frequently Asked Questions

• What RC vehicles are compatible with this 3S LiPo battery? — This battery suits any RC model with an EC3 connector socket and a battery bay approximately 105 x 36 x 18mm in dimensions. This includes numerous electric RC cars, RC buggies, RC stadium trucks, RC short course trucks, RC crawlers, and RC aircraft that use 3S 11.1V battery configurations. Always verify your specific model's battery requirements before purchasing.
• Is the Radient 3S 1800mAh 11.1V 30C battery suitable for beginners? — Yes, this battery is recommended for users aged 14 and above. Beginners should always follow proper LiPo handling procedures, use a dedicated LiPo charger, avoid over-discharging (don't run batteries until they're completely flat), and store batteries in a safe LiPo bag. The 30C discharge rating is moderate and forgiving, making it more suitable for recreational use than extreme performance applications.
• How long does the Radient 3S 1800mAh battery last per charge? — Runtime depends entirely on your specific RC vehicle's motor, ESC, driving style, and terrain. Smaller, lighter vehicles with efficient motors may achieve 15-20 minutes of continuous operation, whilst larger vehicles or those with higher power demands may achieve 8-12 minutes. You should purchase multiple batteries to enjoy extended play sessions without waiting for recharge time.
• What charger do I need to charge this EC3 battery? — You must use a dedicated LiPo battery charger with 3S capability. Do not attempt to charge LiPo batteries with standard NiMH chargers, as this will damage the battery and create serious safety hazards. Recommended chargers should have balance-charging capability and automatic cell detection for 3-cell packs.
• What is the EC3 connector and why does it matter? — The EC3 is a standardised connector used widely throughout the RC hobby industry. It provides secure connections between battery and vehicle, with gold-plated contacts that resist corrosion and minimise electrical resistance. If your RC vehicle uses a different connector type (such as XT60, Deans, or Traxxas connector), you will need an EC3 adapter lead or connector conversion kit.
• How should I store this LiPo battery safely? — Store the Radient battery in a cool, dry place away from direct sunlight and heat sources. Use a dedicated LiPo storage bag or fireproof container to contain any potential cell failure. Store at approximately 50% charge if the battery will be idle for extended periods. Check the battery monthly and recharge if voltage drops below 3.0V per cell (9.0V total).
• How many amps can this battery safely discharge? — The 30C rating means this 1800mAh battery can safely deliver 54 amps of continuous current. Peak discharge can go higher for brief periods, but sustained discharge above the 30C rating will reduce battery lifespan and generate excessive heat.
