Key Features
- 3S (11.1V) Configuration — This three-cell arrangement delivers 11.1 volts nominal output, which is the standard voltage for countless RC models sold in the UK and worldwide, ensuring broad compatibility across different vehicle types and manufacturers.
- 1800mAh Capacity — The 1800mAh storage capacity provides a practical balance of runtime and weight, giving you sufficient power for extended driving sessions without adding unnecessary bulk to your RC model.
- 30C Discharge Rating — A 30C continuous discharge rating means this battery can safely deliver 54 amps of current (30 times 1.8 amps), providing plenty of power for responsive acceleration and dynamic handling without thermal stress.
- Deans (HCT) Connector — The Deans connector is the industry standard for many RC applications, offering reliable electrical contact and easy hot-swapping between compatible models, making this battery incredibly practical for multi-vehicle enthusiasts.
- Compact Dimensions — At just 105mm long, 36mm wide and 18mm tall, this battery pack fits into tight battery bays where larger capacity packs would simply not fit, expanding the range of models you can power.
- Soft Case Protection — The battery comes in a soft protective case that shields the cells from physical damage during transport and storage, extending the pack's lifespan and maintaining safety standards.
- Lithium Polymer Technology — LiPo chemistry delivers superior energy density compared to older NiMH batteries, meaning you get more power from a lighter package, directly improving your RC model's acceleration and handling.
Technical Performance
The Radient LiPo 3S 1800mAh 11.1V 30C battery pack represents modern lithium polymer engineering built to rigorous quality standards. At 0.16kg shipping weight, this is a genuinely lightweight power source that won't bog down your RC car, truck, or other model with excessive mass. The 30C discharge rating is scientifically derived from the pack's 1800mAh capacity, allowing safe continuous current draw of up to 54 amps — more than sufficient for electric RC vehicles ranging from small buggies to mid-sized monster trucks. The 11.1V nominal voltage is the optimum choice for brushless motor systems rated for 3S operation, delivering the voltage sweet spot where torque delivery and top-end performance are both well-balanced. The Deans (HCT) connector has become the gold standard across much of the RC industry for good reason: it provides low-resistance electrical contact, can be connected and disconnected hundreds of times without degradation, and is instantly recognisable across UK RC retailers and clubs. The compact 105 x 36 x 18mm form factor is specifically designed to fit the battery bays found in popular RC models from leading manufacturers, making this a drop-in power upgrade for countless existing setups. Whether used in entry-level models or more demanding performance builds, this battery pack maintains stable voltage delivery thanks to the low internal resistance inherent in properly manufactured LiPo cells.

Frequently Asked Questions
- What RC models can I use this 3S 1800mAh LiPo battery with? — This battery pack is compatible with any RC model that accepts a 3S (11.1V) LiPo battery with a Deans (HCT) connector and has a battery bay approximately 105 x 36 x 18mm in size. This includes popular RC cars, buggies, trucks and other electric RC vehicles from many leading manufacturers. If you're unsure whether it fits your specific model, measure your battery compartment or consult your vehicle's manual.
- Is this battery suitable for beginners to the RC hobby? — This product is recommended for users aged 14 and above who have experience with lithium polymer battery handling and safety. If you're brand new to the RC hobby, we recommend speaking with our team at RC Model Shop to ensure you understand proper LiPo charging, storage and safety practices before purchasing, as improper handling can lead to battery damage or safety issues.
- How long does a 1800mAh battery last on a single charge? — Runtime varies significantly depending on your RC model's motor power, driving style and terrain. As a general guide, a 30C battery with 1800mAh capacity will typically provide 15-25 minutes of moderate driving, though aggressive acceleration and high-speed running will reduce this duration. For longer sessions, we recommend purchasing a second pack to swap in.
- What does the 30C discharge rating mean? — The 30C rating indicates that this battery can safely deliver 30 times its 1800mAh capacity in continuous current, which equals 54 amps. This is sufficient for most electric RC models and provides stable voltage delivery even during hard acceleration. Higher discharge ratings allow more peak current but are not necessary for standard recreational driving.
- Do I need a special charger for this LiPo battery? — Yes, you must use a dedicated LiPo-compatible charger. Standard NiMH chargers will not work and may damage the battery. A proper LiPo charger balances the individual cells, monitors temperature and prevents overcharging, all of which are essential for safety and longevity.
- How should I store this battery when not in use? — LiPo batteries should be stored in a cool, dry place at approximately 3.85V per cell (around 11.5V for this 3S pack) when not actively using your RC models. Long-term storage at full charge or fully depleted significantly reduces battery lifespan. Use your charger's storage mode function if available.
