Key Features

• 2S Cell Configuration (7.4V) — The two-cell lithium polymer arrangement delivers 7.4 volts of nominal voltage, providing the right balance of power and performance for lightweight RC models without the complexity of higher cell-count packs.
• 1800mAh Capacity — This mid-range capacity offers sufficient runtime for recreational driving and testing sessions, allowing you to enjoy extended play periods without constant recharging interruptions.
• 30C Discharge Rating — The 30C rating means this battery can safely deliver 54 amps of continuous current (1.8Ah × 30C = 54A), providing enough power for electric motors in small RC cars, trucks, and buggies without overloading the cells.
• EC3 Connector — The EC3 connection system is widely used across affordable and mid-range RC models, ensuring straightforward integration with many popular UK ready to run RC vehicles and aftermarket receivers.
• Soft Case Protection — The battery arrives in a protective soft case that prevents damage during storage and transport, helping maintain cell integrity and extending the overall lifespan of your investment.
• Compact Dimensions — Measuring 108mm long, 35mm wide, and just 12mm tall, this pack fits into tight battery compartments typical of small RC cars and trucks, making it ideal for vehicles with limited space.
• Lightweight at 99g — At just 99 grams, this battery adds minimal weight to your RC model, helping preserve handling dynamics and acceleration characteristics critical for responsive driving.

Technical Performance

The Radient LiPo 2S 1800mAh 7.4V 30C battery represents solid engineering for the RC hobbyist who demands reliability without premium pricing. The 2S (two-cell series) configuration is the standard entry point for electric RC power, offering a nominal voltage of 7.4 volts that suits a broad spectrum of brushless and brushed motors found in consumer-grade RC cars throughout the UK. The 30C discharge rate provides ample current delivery for recreational driving, with the battery capable of sustaining 54 amps of continuous discharge—sufficient for motors drawing moderate currents in small-scale RC vehicles. The 1800mAh capacity strikes a practical balance; it is neither so small that you constantly need to recharge between runs, nor so large that it becomes unwieldy in compact battery bays. The physical dimensions of 108 × 35 × 12mm make this pack compatible with most small RC cars and buggies designed around standard 2S LiPo packs. Construction quality is consistent with Radient's reputation for delivering solid mid-range batteries that perform reliably across hundreds of charge cycles when properly maintained. The EC3 connector uses gold-plated contacts that resist corrosion and ensure low-resistance connections critical for efficient power delivery. The soft case casing protects cells from puncture and environmental damage whilst remaining light enough not to add unnecessary weight. Temperature stability during discharge is respectable for a battery in this category, though users should avoid driving in extreme cold where performance may temporarily diminish. Charge time is reasonable with most modern 2S-compatible chargers, and the battery's low internal resistance allows for quick recharge cycles between sessions.

Frequently Asked Questions

• Is the Radient 2S 1800mAh LiPo suitable for beginners in RC car UK? — Yes, this battery is an excellent choice for beginners and casual hobbyists. The 2S voltage and 30C rating are standard for many entry-level ready to run RC cars and buggies. Its compact size and lightweight design make it easy to handle, and the soft case provides protection during learning phases when you are still getting to grips with battery safety and charging protocols.
• What RC models will this 7.4V battery work with? — This battery is compatible with any RC model equipped with a 2S LiPo connector (typically EC3 in this case). Most small electric RC cars, buggies, and trucks sold as ready to run or RTR packages in the UK will accept a 2S battery. Always verify your vehicle's battery compartment specifications and connector type before purchase to ensure compatibility.
• How long will the 1800mAh battery run for? — Runtime depends on your specific RC vehicle, motor type, driving style, and terrain. As a general guide, you can expect 15 to 25 minutes of continuous driving with an 1800mAh pack in typical small RC cars, though aggressive racing or high-speed driving will reduce this timeframe. Conservative, casual driving extends runtime significantly.
• What charger do I need for this LiPo battery? — You will need a LiPo-compatible battery charger that supports 2S batteries with EC3 connectors. Many modern chargers are universal and handle multiple battery types and connector styles. RC Model Shop stocks a range of suitable chargers; our team can recommend the right option for your needs if you contact us.
• Is the 30C discharge rating enough power for my RC car? — The 30C rating is perfectly adequate for casual driving, recreational use, and moderate performance RC vehicles. It is commonly found on entry and mid-range ready to run packages. If you plan competitive racing or high-speed bashing, you may want to explore higher discharge-rated batteries (50C or above), but for standard use, 30C is entirely sufficient.
• How should I store this LiPo battery? — Store your Radient LiPo in the protective soft case provided, in a cool, dry location away from direct sunlight and extreme temperatures. If you plan storage lasting more than a few weeks, charge the battery to approximately 50% capacity and store in a fireproof container. Never store fully charged or fully discharged batteries for extended periods, as this accelerates cell degradation.
• What is the difference between a 2S and 3S LiPo battery? — A 2S battery has two cells in series (7.4V nominal), whilst a 3S battery has three cells (11.1V nominal). The 3S delivers higher voltage, resulting in faster speeds and more aggressive acceleration, but requires a compatible motor and ESC. The 2S is better suited to smaller, lighter RC vehicles and provides more measured, controllable performance ideal for learning.
