Frequently Asked Questions

• What RC vehicles is this 4S LiPo battery compatible with? — This battery is compatible with any RC model that accepts a 4S 14.8V LiPo battery with a Deans (HCT) connector. This includes many electric RC buggies, RC trucks, RC crawlers, RC short course trucks and RC cars available throughout the UK market. Check your vehicle's battery specification before purchasing to ensure compatibility, as battery bays vary in size and connector type.
• How long will this battery last per charge? — Runtime depends on several factors including your vehicle's motor power, driving style, terrain, and whether you're using the battery continuously or in shorter bursts. As a general guide, a 4000mAh 4S battery in a typical RC buggy or truck should provide between 15 to 30 minutes of active driving time, though high-performance vehicles with powerful brushless motors may use the battery faster.
• Is this battery suitable for beginners? — Whilst this battery is recommended for users aged 14 and upwards, it does require proper knowledge of LiPo care and safety procedures. Beginners should familiarise themselves with LiPo charging safety, proper storage in a LiPo bag, and the correct handling procedures before using this battery. If you're new to RC, we recommend seeking advice from experienced RC enthusiasts at your local club or from the RC Model Shop team.
• What does the 50C rating mean? — The 50C rating indicates the maximum safe continuous discharge rate for the battery. A 50C rating on a 4000mAh battery means it can safely discharge at 200 amps continuously (4000mAh × 50 = 200A). This high discharge rate makes it suitable for high-performance RC vehicles that demand significant current during acceleration and full-throttle driving.
• What charger do I need for this battery? — You'll need a dedicated LiPo battery charger that supports 4S charging. A balance charger is strongly recommended to ensure each cell charges evenly and safely, helping to extend battery lifespan and prevent cell imbalance issues. The Deans (HCT) connector on this battery is compatible with most RC chargers available in the UK market.
• How should I store this battery? — LiPo batteries should be stored in a cool, dry location at around 50% charge (approximately 3.8V per cell or 15.2V total for this 4S pack). Store the battery in a dedicated LiPo safe bag or fireproof container to contain any potential issues. Never store fully charged or fully discharged batteries for extended periods.
• What is the difference between this and other 4S LiPo packs? — This Radient pack offers a 50C discharge rating, which is solid for performance RC applications. Some batteries offer higher discharge ratings (60C or above) but may be more expensive, whilst others offer lower ratings but may be cheaper. The 4000mAh capacity is ideal for mid-range RC vehicles; smaller capacities (2000-3000mAh) reduce runtime whilst larger capacities (5000mAh+) increase weight and size.
• How do I know if this battery will fit my RC vehicle? — Check your vehicle's battery bay dimensions in the manual or specification sheet. This battery measures 135mm long, 42mm wide and 32mm high. If your vehicle's battery compartment can accommodate these dimensions and has a Deans (HCT) connector, this battery will be compatible.
