Key Features

• 30C Continuous Discharge Rating — This high discharge rate delivers consistent, sustained power output to your motors throughout your flight, enabling rapid acceleration and responsive control while maintaining the battery's reliability and longevity even under demanding conditions.
• Protective Metal Alloy Outer Sheet — The protective outer metal alloy casing serves three critical functions: it effectively dissipates heat away from the cells to prevent thermal stress, maintains the battery's rigid shape to ensure proper fit in your model, and significantly increases overall durability to withstand impacts and regular use in the field.
• Compact 450mAh Capacity — The 450mAh capacity is purpose-designed for micro and mini RC aircraft and helicopters, offering enough energy for extended flight times whilst maintaining the lightweight profile essential for small-scale models that must stay within strict weight limits for optimal performance.
• Factory-Installed IC2 Connector — The IC2 connector is pre-installed at the factory, eliminating the need for additional installation work and ensuring a secure, reliable electrical connection between your battery and your model's speed controller every single time you fly.
• Integrated Balancing Lead — The balancing lead is included and compatible with the vast majority of LiPo battery chargers and balancers available to RC hobbyists in the UK, allowing you to maintain perfect cell balance and maximise battery performance and lifespan with routine maintenance.
• Up to 5C Charge Rating — The 5C maximum charge rating means you can recharge this battery quickly between flights without damaging the cells, enabling you to spend more time flying and less time waiting by providing rapid turnaround between sessions.
• 4S Cell Configuration — With four cells in series, this battery delivers 14.8V nominal voltage, providing the power output required by most micro to mini RC aircraft and helicopter speed controllers and flight systems for responsive, dynamic flight characteristics.

Technical Performance

The Spektrum 450mAh 4S 14.8V 30C LiPo Battery represents careful engineering for the micro and mini RC segment. With a nominal voltage of 14.8V across four 3.7V cells in series configuration, this battery provides the output required by most small-scale electric RC aircraft and helicopter systems. The 30C continuous discharge rating is particularly significant for this capacity class, enabling the battery to deliver up to 13.5 amps of continuous discharge current, making it suitable for brushless motor systems commonly found in modern RC aircraft. The protective metal alloy casing isn't merely decorative—it plays a vital functional role in the battery's performance and longevity. By actively dissipating heat generated during discharge cycles, the metal housing helps maintain optimal operating temperatures and prevents thermal stress on the lithium polymer cells, which would otherwise degrade their capacity and lifespan. The rigid structure provided by this casing ensures that the battery maintains its compact shape, preventing the physical deformation that can occur with standard plastic-cased batteries and ensuring consistent fit within tight fuselage compartments in foam aircraft. The 450mAh capacity represents the sweet spot for micro-scale models where every gram counts—the battery is lightweight enough to be carried by ultra-light foam aircraft yet has sufficient energy capacity to deliver meaningful flight times of several minutes depending on motor size and flight style. The factory-installed IC2 connector ensures quality and consistency in the electrical connection, whilst the integrated balancing lead with standard JST-XH connector compatibility means this battery works seamlessly with balancers and chargers commonly used by RC hobbyists throughout the UK. Build quality is reliable and predictable, with genuine Spektrum manufacturing standards ensuring safety and performance.

Frequently Asked Questions

• Is the Spektrum 450mAh 4S LiPo battery suitable for my micro foam RC aircraft? — Yes, this battery is specifically designed for micro to mini foam aircraft and helicopters where compact size and lightweight characteristics are essential. The 450mAh capacity provides sufficient energy for several minutes of flight time depending on your motor size, whilst the metal alloy protection ensures the battery maintains its shape within tight fuselage compartments.
• What is the difference between this Spektrum battery and standard RC car batteries? — This is a purpose-built aerial battery optimised for small, lightweight aircraft where weight is absolutely critical. Whilst RC car batteries prioritise high capacity and maximum discharge rates, this aerial battery prioritises minimum weight and compact dimensions. The 450mAh capacity would be considered very small for ground vehicles but is perfectly proportioned for micro-scale aircraft.
• How long does this battery take to charge? — With the 5C charge rating, this 450mAh battery can accept a maximum charge current of 2.25 amps. Charge time depends on your charger's settings, but at 2C charge rate (0.9A), you can expect a full charge in roughly 30 minutes, making this battery ideal for between-flight charging sessions at the field.
• Is this battery compatible with existing RC equipment? — The factory-installed IC2 connector is one of the most common connectors in the RC hobby and works with the vast majority of small-scale speed controllers. The integrated JST-XH balancing lead is compatible with most LiPo chargers and balancers used by RC pilots in the UK, ensuring straightforward integration into your existing charging setup.
• What makes the metal alloy protection important? — The protective metal alloy outer sheet serves multiple critical functions beyond appearance. It actively dissipates heat away from the battery cells during discharge, preventing thermal stress that would degrade performance and lifespan. It maintains the battery's rigid structure, preventing physical deformation that can occur with standard plastic cases. Finally, it significantly increases the battery's durability and resilience to impacts during handling and field use.
• Can I use this battery in my RC helicopter? — Yes, this battery is specifically designed for micro and mini RC helicopters. The compact 450mAh capacity provides suitable flight times whilst maintaining the lightweight profile essential for small-scale helicopter airframes. Ensure your helicopter's speed controller is rated for 4S LiPo batteries before use.
• What is the lifespan of this LiPo battery? — LiPo battery lifespan is measured in charge cycles rather than calendar time. Proper maintenance including regular cell balancing, avoiding complete discharge, storing at moderate charge levels when not in use, and keeping the battery at appropriate temperatures all extend lifespan significantly. With proper care, this Spektrum battery should provide 100-200+ charge cycles.
