Frequently Asked Questions

• What voltage does the Radient 3S 4000mAh battery provide? — The battery delivers 11.1V nominal voltage across its three cells, with each cell contributing 3.7V. This is the standard voltage for 3S LiPo configurations and is widely supported by modern RC electronics and brushless motors available throughout the UK market.
• Is the Radient 3S LiPo suitable for beginners? — Yes, this battery is suitable for users aged 14 and upwards, making it appropriate for older teenagers and adults new to the hobby. However, all users should follow proper LiPo safety procedures, including charging with an appropriate balance charger and storing in a cool, dry location away from flammable materials.
• What vehicles can I use this battery in? — With its 4000mAh capacity and 30C discharge rating, this battery works well in 1/10 and smaller scale RC cars, buggies, truggy trucks, crawlers, and quadcopters or drones that accept 3S LiPo batteries and XT60 connectors. Check your vehicle's documentation to confirm 3S compatibility before use.
• How long will this battery last per charge? — Runtime depends entirely on your motor's power consumption and driving style. Typical runtimes range from 15 to 40 minutes depending on vehicle type, motor size and whether you're driving at full throttle or more gently. Brushless motors generally offer extended runtimes compared to brushed alternatives.
• What charger do I need for this battery? — You'll need a dedicated LiPo battery charger capable of balancing 3-cell packs and accepting XT60 connectors. Most modern RC battery chargers sold in the UK support 3S LiPo charging. Always use a charger rated for LiPo batteries — never use a standard NiMH charger as this will damage the battery and create a safety hazard.
• What is the 30C rating and why does it matter? — The 30C discharge rating indicates the maximum safe continuous current the battery can deliver. At 4000mAh, a 30C rating means the battery can safely provide up to 120A of current (4 × 30 = 120). This ensures your motor and ESC receive consistent voltage during hard acceleration or heavy load conditions without the battery overheating or entering protection mode.
• What is the XT60 connector and why is it important? — The XT60 is one of the most popular connector standards for RC LiPo batteries in the UK and worldwide. Its gold-plated contacts provide excellent electrical conductivity and reliability. The XT60 standard ensures compatibility with most modern ESCs, chargers and RC equipment, eliminating the need for custom adapters.
• How should I store and maintain this battery? — Store your Radient LiPo in a cool, dry location away from direct sunlight and extreme temperatures. When not in use for extended periods, discharge the battery to its storage voltage (typically 3.85V per cell, or about 11.55V for 3S) using a LiPo discharger function on your charger. This helps maximise the battery's lifespan and maintains cell health. Inspect the case regularly for damage and never use a damaged battery.
• Is this battery waterproof? — Whilst the soft case provides basic protection, this battery is not designed for submersion in water. Exposure to moisture can damage the cells and create safety risks. Keep this battery away from water, muddy tracks and wet conditions.
