Key Features

• 2S LiPo Configuration (7.4V) — This two-cell lithium polymer pack delivers the 7.4 volts needed to power a huge range of electric RC cars, trucks, crawlers and buggies available in the UK market, making it one of the most versatile battery voltages for general-purpose RC use.
• 1800mAh Capacity — With 1800 milliamp-hours of capacity, this battery provides sufficient runtime for extended driving sessions whilst maintaining the compact size that allows installation in models with limited battery bay space.
• 30C Continuous Discharge Rating — The 30C rating means this battery can safely deliver 54 amps of continuous current (1.8Ah × 30C), providing plenty of power for brushless motors, brushed motors and high-performance ESC setups without thermal stress or voltage sag.
• Ultra-Slim 12mm Height — The incredibly thin 12mm profile is the standout physical feature of this pack, allowing it to fit into compact battery compartments on low-profile RC models where conventional rectangular batteries would not fit at all.
• Lightweight 99g Construction — At just 99 grams, this battery adds minimal weight to your RC model, helping maintain optimal centre of gravity and handling characteristics, particularly important in racing and competitive RC applications.
• Deans (HCT) Connector — The industry-standard Deans connector ensures compatibility with the majority of modern RC equipment, from brushless ESCs to ready to run RC vehicles, reducing the need for adapter cables and connector conversions.
• Soft Case Protection — The battery is housed in a protective soft case that safeguards the cells during storage, transport and occasional impacts, whilst remaining flexible enough to fit into confined spaces.
• Genuine Radient Manufacturing — Built to Radient's established quality standards, this battery benefits from proper cell matching, protection circuitry and quality control testing to ensure reliability throughout its operational life.

Technical Performance

The Radient LiPo 2S 1800mAh 7.4V 30C battery is engineered to provide consistent, stable power delivery across a broad range of RC applications. The 30C continuous discharge rating ensures that this pack can comfortably handle demanding motor and ESC combinations without excessive voltage sag, a critical factor in maintaining responsive handling and top speed in competitive RC environments. The 7.4V nominal voltage of a 2S pack makes it ideal for a vast array of brushless and brushed motor setups, whilst the 1800mAh capacity represents a sweet spot between runtime and pack weight—generous enough for meaningful driving sessions, yet light enough to preserve model dynamics. The ultra-slim 12mm height is achieved through intelligent cell arrangement and careful engineering, allowing this pack to be integrated into models that simply cannot accommodate standard rectangular battery formats. The protective soft case provides adequate thermal management and physical protection during normal use, whilst the genuine Deans (HCT) connector ensures secure, low-resistance power delivery with minimal voltage drop. With dimensions of 108mm length, 35mm width and 12mm height, this battery can be oriented vertically, horizontally or at angles to suit your specific model layout, making it exceptionally versatile for custom RC builds and modifications.

Frequently Asked Questions

• What RC models are compatible with the Radient 2S 1800mAh 7.4V battery? — This 2S LiPo pack is compatible with the vast majority of electric RC cars, trucks, buggies, crawlers and short course trucks available in the UK market that accept 2S LiPo batteries with Deans connectors. Common applications include 1/10 scale brushless buggies, monster trucks, stadium trucks and crawler models. Always verify your specific model's battery requirements before purchasing, as some models may require different voltage configurations or connector types.
• Is this battery suitable for beginners to RC hobbies? — This Radient battery is suitable for RC enthusiasts aged 14 and above with basic understanding of LiPo battery safety and handling. Beginners should familiarise themselves with LiPo charging procedures, storage requirements and safety precautions before use. Adult supervision is recommended for younger users. The battery itself is reliable and forgiving, but LiPo batteries do require proper care and attention compared to older battery technologies.
• What charger do I need to charge this 2S LiPo battery? — You'll need a LiPo-compatible battery charger capable of charging 2S packs. Modern multi-chemistry chargers from brands like Spektrum, Hobbywing and others can handle 2S LiPo packs safely. The charger must support the Deans connector or you'll need an adapter. Balance charging is highly recommended to maintain optimal cell health and longevity. Do not attempt to charge this battery with standard NiMH or NiCd chargers.
• How long will this battery last on a single charge? — Runtime depends entirely on your specific RC model, motor, ESC settings, driving style and terrain. A 1800mAh capacity in a medium-to-low current application might provide 20-40 minutes of driving, whilst high-power brushless setups may drain it in 10-15 minutes. Conservative, technical driving yields longer runtimes than aggressive, high-throttle driving.
• What does the 30C discharge rating mean? — The 30C rating indicates the maximum continuous current this battery can safely deliver. Calculated as capacity times the C rating (1.8Ah × 30C), this battery can provide up to 54 amps of continuous current without damage. This rating ensures the battery can handle demanding brushless motor and ESC combinations without overheating or voltage collapse.
• Is the 12mm slim profile guaranteed to fit my specific RC model? — The 12mm height is genuinely slim and fits many compact battery compartments, but you must verify your model's battery bay dimensions before purchase. Measure your battery compartment's length, width and height carefully. The pack measures 108mm long by 35mm wide by 12mm tall, so confirm these dimensions work for your application.
• How should I store this battery when not in use? — LiPo batteries should be stored in a cool, dry location at room temperature, ideally in a fireproof storage pouch or LiPo bag. Store the battery at approximately 50% state of charge (around 3.7V per cell, or 7.4V total for a 2S pack) if you won't be using it for extended periods. Never store fully charged or fully discharged. Check cells occasionally to ensure they remain balanced and haven't puffed or swollen.
• Can I use this battery with my brushed motor RC car? — Yes, this 2S 7.4V battery is fully compatible with brushed motor setups. It will provide adequate power for most brushed motor applications in RC cars, trucks and crawlers. Brushed motors are generally more tolerant of battery voltage and discharge rates than brushless systems, so this battery will work reliably with quality brushed ESCs and motors.
