Technical Performance

The Corally Sport Racing 50C LiPo Battery represents the pinnacle of hobby-grade lithium polymer cell technology. Built using genuine lithium polymer cells rather than knockoff alternatives, this battery benefits from manufacturing expertise accumulated over more than 15 years in high-discharge battery production. The continuous 50C discharge rating is not merely a marketing specification—it represents genuine capability, with the battery capable of safely delivering 225 amps of continuous current to your brushless ESC without reaching unsafe temperature levels. The 4500mAh capacity provides excellent runtime without excessive weight penalties, making it the ideal choice for RC cars where mass directly impacts acceleration, cornering speed, and handling characteristics.

The construction quality is evident in every detail. The hard case protects the cylindrical cell arrangement from crushing impacts that might occur during transport or racing accidents. The dimensions of approximately 138mm length by 47mm width by 48mm thickness allow this battery to fit into the battery compartments of modern competition-grade RC car chassis. At 587 grams without the wire assembly, this battery delivers significant power capacity whilst remaining light enough for high-performance applications. The engineering behind the cell selection process is particularly noteworthy—Team Corally's quality assurance process ensures that only cells with minimal internal resistance variation make it into production packs, which means faster charge acceptance (up to 3C charge rate, or 13.5 amps maximum), more even power delivery throughout the discharge cycle, and longer overall lifespan measured in hundreds of charge cycles.

Frequently Asked Questions

• Is the Corally Sport Racing 50C LiPo Battery suitable for competitive RC car racing in the UK? — Yes, absolutely. The 50C continuous discharge rating, premium cell matching, and advanced lithium polymer chemistry make this battery ideal for competitive applications where consistent power delivery, cycle longevity, and reliability are paramount. Many UK RC racing competitors trust Team Corally batteries for their competition vehicles.
• What is the maximum charge rate for this battery and how long does it take to charge? — The Corally Sport Racing 50C LiPo can accept charge rates up to 3C, which equals 13.5 amps maximum charge current (calculated from the 4500mAh capacity). Using a 3C charger, the battery would reach full charge in approximately 20 minutes. Using a 1C charger (4.5 amps), charging would take approximately one hour, though this is gentler on cell longevity.
• What RC car chassis is this battery compatible with? — This 2S 7.4V battery is compatible with virtually all modern brushless RC car platforms operating on 2S LiPo configuration, including touring cars, buggies, truggies, and short course trucks. However, you should always verify that your specific chassis and ESC are rated for 2S LiPo power before purchasing. Many racing series and popular platforms like various 1/10 scale TC, buggy, and SCT classes use 2S batteries.
• How does this battery compare to cheaper alternatives available in the UK hobby market? — The primary difference is in cell quality and manufacturing rigour. Budget hobby batteries often use mixed-grade cells with high internal resistance variation, leading to uneven power delivery, faster degradation, and shorter lifespan. The Corally Sport Racing 50C undergoes meticulous cell matching and uses only highest-grade cells, meaning superior performance, better cycle life, more consistent power delivery across numerous runs, and ultimately better value over the battery's lifespan.
• What safety precautions should I follow when using this LiPo battery? — Team Corally provides comprehensive multilingual safety documentation with this battery covering all essential precautions. Always use a LiPo-compatible charger with balance charging capability, never overcharge or over-discharge cells, store in a cool dry location, never short-circuit the terminals, and follow all guidelines in the included safety documentation. Improper handling of lithium polymer batteries can result in fire or injury.
• Is this battery good for beginners in RC cars? — Whilst the Corally Sport Racing 50C is an excellent battery, beginners should ensure they understand LiPo battery safety, charging procedures, and storage requirements before purchasing. If you're new to RC cars and unfamiliar with lithium polymer battery handling, you may want to start with a ready-to-run RC car that includes a matched battery and charger, then upgrade to this premium battery as you gain experience and confidence.
• What is the weight of this battery? — The battery weighs approximately 587 grams without the wire assembly, making it relatively lightweight for its 4500mAh capacity, which is beneficial for RC car performance where reduced mass improves acceleration and handling.
