Technical Performance

The Radient LiPo 3S 4500mAh 11.1V 30C XT60 battery represents a carefully engineered balance of power delivery, capacity, and physical practicality. The 30C discharge rating indicates this battery can safely provide 135 amps of continuous discharge current (calculated as 4500mAh × 30C ÷ 1000), making it suitable for brushless motor systems demanding responsive acceleration and sustained high-speed running. The 11.1V nominal voltage (3.7V per cell × 3 cells) is the standard for LiPo chemistry and ensures compatibility with ESCs calibrated for 3S systems. The 4500mAh capacity positions this battery in the mid-to-high range for hobby-grade RC applications, offering runtime measured in 10-15 minute intervals depending on motor size, load profile, and driving style. The soft case construction utilises lightweight polymer materials that protect the battery cells from impact damage whilst allowing controlled heat dissipation during high-draw operations. Modern LiPo cells in this pack employ advanced chemistry optimised for cycle life and performance consistency across hundreds of charge-discharge cycles. The XT60 connector features heavy-duty gold-plated contact pins that resist oxidation and maintain low electrical resistance throughout the battery's service life. This battery integrates seamlessly with most ESCs rated for 3S LiPo operation, from entry-level hobby controllers to competition-grade units, making it an excellent choice whether you're running a casual bashing setup or preparing for organised RC racing events across the UK.

Frequently Asked Questions

• Is the Radient 3S 4500mAh battery suitable for my RC car? — The Radient LiPo 3S 4500mAh 11.1V 30C is compatible with any RC vehicle equipped with a 3S LiPo-compatible ESC and XT60 connectors. This includes most mid-range electric RC cars, buggies, and trucks sold in the UK market. Before purchasing, verify your vehicle's manual specifies 3S LiPo compatibility and check whether your ESC features an XT60 connector or if you'll need an adapter harness.
• How long will this battery power my RC model? — Runtime depends on your motor size, ESC programming, and driving style, but typically ranges from 10-15 minutes of continuous use. The 4500mAh capacity provides extended runtime compared to smaller 2200mAh or 3000mAh packs, making this battery excellent for extended bashing sessions or multiple race heats with brief recharge intervals between runs.
• What charger do I need for this battery? — You'll need an LiPo-compatible charger capable of handling 3S packs. Look for chargers that feature XT60 charging connectors or universal connectors with XT60 adapters. Most quality chargers include balance charging functions, which are essential for maintaining individual cell health and extending battery lifespan across hundreds of charge cycles.
• Is this battery safe to use? — LiPo batteries require responsible handling, but when used correctly, they're safe and reliable. Always charge in a controlled environment, never leave charging batteries unattended, store in a cool dry location, and never allow the battery to completely discharge below 3.0V per cell. The 14+ age recommendation reflects these safety considerations, and adult supervision is advisable for younger hobbyists.
• What does the 30C discharge rating mean? — The 30C rating indicates the maximum safe continuous discharge current, calculated by multiplying capacity by the C-rating (4500mAh × 30 = 135A). This rating ensures the battery can safely power demanding brushless motors without excessive heat generation or voltage sag, maintaining responsive performance throughout your driving session.
• Will this battery work with my existing RC charger? — Compatibility depends on your charger's connector type. If your charger features an XT60 connector or universal charging ports with XT60 adapters, this battery will work perfectly. Most modern UK RC retailers, including RC Model Shop, stock a wide range of compatible chargers, and our team can advise on the best option for your specific needs.
• How should I store this battery between uses? — Store the Radient battery in a cool, dry location at approximately 50% charge state, ideally in a dedicated LiPo storage bag or fireproof container. Never store fully charged or fully discharged batteries, and regularly check that individual cells maintain balanced voltage levels using a simple battery monitor.
