For most RC cars and trucks, this capacity translates to 15-25 minutes of continuous running, depending on the load and driving style.
• 50C Continuous Discharge Rating — The 50C rating indicates this pack can safely deliver 225 amps of current continuously (4500mAh × 50C = 225A), which is more than sufficient for high-performance RC applications including brushless motors with upgraded ESCs. This rating ensures the battery won't become a limiting factor in your setup, allowing your motor and ESC to reach their full potential without voltage sag compromising performance.
• Deans (HCT) Connector — The Deans-style connector is the most popular battery connector in the RC hobby, particularly in the RC car UK community. This widespread adoption means you'll find compatible chargers, balance leads, and distribution boards readily available, and you can easily swap this battery between multiple vehicles without requiring adapter cables.
• Compact Dimensions of 137 × 43 × 19mm — These precise measurements allow you to verify fitment in your specific RC model before purchasing, ensuring compatibility with tight battery compartments. The rectangular profile packs efficiently into most modern vehicle designs without excessive wasted space.
• Soft Case Construction — Unlike hard cases that add weight and bulk, the soft case design balances protection of the delicate lithium polymer cells with minimal mass penalty. The case protects the pack from minor impacts during transport and storage whilst allowing for efficient heat dissipation during discharge.
• Lightweight at Just 232 Grams — Keeping rotational and unsprung mass low is critical for RC handling and suspension performance. At 232g, this battery won't bog down your vehicle's acceleration or adversely affect weight distribution, allowing your chassis setup to work as intended.
• Suitable for Ages 14 and Above — This age recommendation reflects the maturity and responsibility required to safely handle, charge and maintain lithium polymer batteries. Younger operators should always work under direct adult supervision with LiPo packs.

Technical Performance

The Radient LiPo 2S 4500mAh 7.4V 50C battery represents a well-engineered balance of capacity, discharge capability and physical characteristics for the demanding RC hobby market. The 50C discharge rating is derived from the nominal capacity and represents the maximum safe continuous current draw — in this case, 225 amps. This specification is particularly important for RC applications because it determines how much current the battery can supply without experiencing excessive voltage drop (sag) or heat generation that could degrade cell lifespan. The two-cell configuration produces a nominal voltage of 7.4V when fully charged to 2 cells × 3.7V per cell, dropping to 6.0V at the fully discharged state (2 × 3.0V per cell). Most ESCs and motor systems are specifically designed and tuned for 2S operation, making this the most widely used battery voltage in recreational RC car UK applications. The lithium polymer chemistry delivers superior energy density compared to older NiMH and NiCd batteries, meaning you get more runtime and power from a lighter package. Modern LiPo cells employ safety features including internal pressure vents and thermal protection to help prevent catastrophic failure, though proper charging and storage practices remain essential. The 4500mAh capacity sits in the sweet spot for most popular RC vehicles — larger than compact 3000mAh packs but more practical than bulky 5000-6000mAh options that may not fit standard battery trays. The Deans connector specification ensures reliable electrical contact with minimal resistance, preserving voltage delivery to your motor even under high current draw. Radient's reputation for consistent quality manufacturing means this battery will deliver reliable performance across hundreds of charge cycles when properly maintained and stored in a cool, dry location.

Frequently Asked Questions

• Is the Radient 2S 4500mAh LiPo battery suitable for beginners in the RC hobby? — Yes, this battery is an excellent choice for RC beginners who have progressed beyond basic 1S packs. The 2S voltage is the most common in the RC car UK market, and the 4500mAh capacity provides meaningful runtime for learning. However, beginners must understand proper LiPo handling, charging procedures and safety precautions before using any lithium polymer battery. Always charge under supervision on a dedicated LiPo charger, never charge directly from a wall outlet, and store the battery in a cool location. Age recommendation of 14+ reflects the responsibility required.
• What RC vehicles is the Radient 2S 4500mAh compatible with? — This battery is suitable for any 2S LiPo-compatible RC vehicle with a Deans connector that has available space for a pack measuring 137 × 43 × 19mm. This includes most 1/10-scale RC buggies, stadium trucks, short-course trucks, and touring cars, as well as many 1/8-scale vehicles. Always verify your specific model's battery requirements before purchasing. The specifications clearly state 2S (7.4V) compatibility, so ensure your ESC, motor and charging system are all rated for 2S operation.
• How long will this battery run before needing recharge? — Runtime depends entirely on your specific vehicle, motor, ESC settings and driving style. As a general guideline, expect 15-25 minutes of continuous running for typical RC cars, with lighter vehicles or lower-power setups achieving longer times and high-performance brushless setups potentially using the battery faster. The only way to determine exact runtime for your application is field testing.
• Can I use this battery with my existing charger? — That depends on your charger. The Radient 2S 4500mAh pack is a standard LiPo battery, so any balance charger capable of charging 2S LiPo packs with a Deans connector will work. Many modern multi-chemistry chargers support LiPo charging. However, never attempt to charge a LiPo battery on a NiMH or NiCd-specific charger, as this can damage the battery or create a safety hazard. If you're unsure about your charger's capabilities, contact RC Model Shop for guidance — our team can recommend compatible charging solutions.
• What is the discharge rating and why does it matter? — The 50C discharge rating means this battery can safely deliver 225 amps of continuous current (4500mAh × 50 = 225A). This matters because it directly impacts how responsive your RC vehicle will feel under acceleration and cornering, and whether the battery becomes the limiting factor in your performance. A battery with insufficient discharge rating will experience voltage sag — a temporary drop in voltage under load — which makes your motor and ESC less responsive. The 50C rating is more than adequate for most recreational and even competitive 2S applications.
• How should I store this battery when not in use? — Store your Radient LiPo battery in a cool, dry location away from direct sunlight and heat sources. Ideally, store the pack at approximately 50% state of charge (around 7.0-7.2V) if you don't plan to use it for extended periods. Check the voltage periodically and top up if it drops below 6.0V, as fully discharged LiPo packs can suffer permanent damage. Never leave a LiPo battery in a hot car or exposed to freezing temperatures, as extreme temperatures degrade cell lifespan and can create safety hazards.
• Is the Deans connector the right one for my setup? — Deans (also called HCT or DT connectors) are the most common battery connectors in the RC hobby, particularly for RC cars. However, some vehicles use XT60, XT90, or proprietary connectors instead. Before ordering, verify that your vehicle's ESC has a Deans-compatible connector. If your ESC uses a different connector type, you'll need an adapter cable or consider a different battery pack. RC Model Shop stocks Radient batteries in multiple connector types, so ask our team if you need an alternative.
