Key Features

• 3S LiPo Chemistry — This battery uses lithium polymer technology arranged in three cells, providing a nominal voltage of 11.1 volts. LiPo batteries are the gold standard in RC hobbying because they offer superior energy density compared to older battery technologies, meaning you get more power in a lighter package, which directly translates to better performance and longer run times for your RC model.
• 2200mAh Capacity — The 2200 milliamp-hour capacity represents a good balance between runtime and practicality. This capacity is sufficient for extended driving sessions on most RC cars and trucks, whilst keeping the battery weight manageable so your vehicle maintains its intended handling characteristics and performance envelope.
• 30C Discharge Rating — The 30C continuous discharge rating means this battery can safely deliver 66 amps of current continuously (2.2Ah × 30C = 66A), making it suitable for moderate to high-performance RC applications. This discharge rating ensures the battery can handle the power demands of typical brushless motor setups found in entry-level to intermediate RC vehicles, whilst maintaining safe operating temperatures and longevity.
• EC3 Main Connector — The EC3 connector is a gold-plated, low-resistance connection system that has become the industry standard for many RC batteries and ESCs throughout the UK and beyond. This connector provides a secure fit, minimises power loss, and ensures you can confidently swap batteries between compatible models without worrying about loose connections or intermittent power delivery.
• Soft Case Protection — The battery arrives in a protective soft case that shields the cells during storage, transport, and charging. This case helps prevent accidental punctures or damage that could compromise the battery's integrity, extending its lifespan and ensuring consistent performance throughout its operational life.
• Compact Dimensions — Measuring just 106mm long, 36mm wide, and 22mm tall, this battery has a compact footprint that fits into standard battery compartments on most RC vehicles. The modest size means you can carry multiple packs to the track or field without adding significant weight to your gear bag, enabling extended driving sessions with battery swaps.
• Approx. 0.20kg Weight — Weighing only 200 grams, this battery contributes minimal additional mass to your RC model, which is crucial for maintaining proper weight distribution, acceleration response, and overall handling characteristics across different vehicle types and driving conditions.

Technical Performance

The Radient LiPo 3S 2200mAh 11.1V 30C battery is engineered to deliver consistent power output across a wide range of RC applications. With its three-cell configuration providing 11.1 volts nominal voltage (which rises to approximately 12.6 volts when fully charged), this battery is compatible with countless RC models throughout the UK market. The 30C discharge rating indicates this battery can sustain continuous output suitable for brushless motor systems ranging from modest 2200KV motors to more aggressive 3000KV+ setups, depending on your specific vehicle's ESC (electronic speed controller) rating and motor specifications. The LiPo chemistry ensures stable voltage delivery throughout the discharge cycle, meaning your RC car or truck will maintain consistent acceleration and top-end speed from the moment you hit the throttle until the battery reaches its minimum safe voltage threshold. The compact 106mm × 36mm × 22mm dimensions ensure fitment in the vast majority of modern RC vehicles available in the UK market, from 1/10-scale buggies and truggies to short-course trucks and stadium trucks. The EC3 connector, widely recognised across the RC hobby as a premium connection system, features gold-plated contacts that deliver lower electrical resistance than standard connectors, meaning more of your battery's power reaches your motor rather than being lost as heat in the connector itself.

Frequently Asked Questions

• Is the Radient LiPo 3S 2200mAh 11.1V 30C suitable for beginners in RC hobbying? — Yes, this battery is well-suited for beginners and intermediate RC enthusiasts. The 30C discharge rating makes it forgiving enough for various motor setups, and the 2200mAh capacity provides adequate runtime for learning sessions without requiring constant battery swaps. The age recommendation of 14+ reflects responsible safety guidance, and with proper charger use and attention to LiPo safety practices, this battery is perfectly safe for teenage and adult hobbyists new to RC vehicles. Always use a dedicated LiPo charger and never leave a LiPo battery charging unattended.
• What type of RC vehicles can use this 3S LiPo battery? — This 11.1V three-cell battery is compatible with most RC cars, trucks, and similar vehicles that feature EC3 connectors and are designed for 3S LiPo power. Common applications include 1/10-scale RC buggies, short-course trucks, stadium trucks, truggies, and various crawler and bashers throughout the UK market. Before purchasing, verify that your RC vehicle's ESC (electronic speed controller) is rated for 3S LiPo operation and that it features an EC3 connector or you have a suitable adapter available.
• How long will this battery run my RC model? — Runtime depends on several factors including your motor's power draw, your driving style, and the terrain. As a general guideline, a 2200mAh capacity with typical brushless motor setups yields approximately 15-25 minutes of continuous driving, though careful, smooth driving can extend this to 30 minutes or more. Higher-performance brushless motors with aggressive driving will consume the battery faster. Many RC enthusiasts keep multiple batteries on hand to extend their hobby sessions without downtime.
• What is the difference between this 2200mAh battery and larger capacity alternatives? — Larger capacity batteries (such as 3300mAh or 5000mAh packs) offer extended runtime but add weight and bulk to your vehicle, potentially affecting handling and acceleration. The 2200mAh capacity strikes an optimal balance for most mid-range RC vehicles, providing sufficient runtime whilst maintaining a lightweight profile that preserves your model's intended performance characteristics. If maximum runtime is your priority and your vehicle has ample battery bay space, larger capacities may be worth considering; however, the 2200mAh size remains the most versatile choice for general RC use.
• What does the 30C discharge rating mean, and why does it matter? — The 30C rating indicates this battery can safely discharge at a rate of 30 times its capacity per hour. With a 2200mAh battery, this means a maximum continuous current draw of 66 amps (2.2 × 30 = 66A). This rating is crucial because it ensures the battery can handle the current demands of your motor and ESC without overheating, voltage sag, or damage. Exceeding a battery's discharge rating risks reduced performance, premature ageing, and potential safety hazards. The 30C rating makes this battery suitable for moderate to high-performance RC applications, though extreme racing or high-current brushless setups may benefit from higher-rated batteries.
• Do I need any adapters or converters to use this battery? — This battery features an EC3 connector, so you'll need an RC vehicle with an EC3-compatible ESC, or you'll need to source an EC3 adapter to connect it to a different connector type. EC3 adapters are readily available from RC retailers throughout the UK, including RC Model Shop, and are inexpensive. Before purchasing, confirm your vehicle's connector type to avoid compatibility issues.
• How should I store and maintain this LiPo battery? — Store your Radient LiPo battery in a cool, dry location away from direct sunlight. The soft protective case provided helps during storage and transport. For optimal longevity, store the battery at approximately 50% charge (around 3.85V per cell, or 11.55V total for a 3S pack). Before each use, visually inspect the battery for any signs of damage, puffing, or deformation. After use, allow the battery to cool before charging, and always charge in a safe location using a dedicated LiPo charger. Never leave a LiPo battery charging unattended, and follow all safety guidelines provided with your charger.
