Overview

The Spektrum 450mAh 4S 14.8V 50C LiPo Battery with JST connector is the perfect power solution for RC hobbyists seeking high-performance energy in a compact, lightweight package. Whether you're flying micro or mini RC aircraft, this battery delivers the punch your model needs whilst maintaining the small footprint essential for agile flight performance. Spektrum's reputation for quality and reliability makes this an excellent choice for UK RC enthusiasts looking to upgrade their aerial fleet or expand their battery collection with a trusted brand.

This 4-cell LiPo battery is specifically engineered for high-power applications where weight savings and performance are critical. The 50C continuous discharge rating ensures your model receives consistent power delivery even during demanding manoeuvres, making it ideal for aerobatic flying, racing, or aggressive flight styles. The factory-installed JST connector means you can get flying straight out of the box without additional modifications or connector swaps, saving you time and hassle.

For those new to the RC battery world or experienced flyers looking for a dependable power source, this Spektrum LiPo represents excellent value. It's designed specifically for the compact airframes common in the micro and mini RC aircraft segment, yet maintains the power output demanded by modern brushless motor systems. The protective metal alloy outer casing isn't just for show—it actively helps dissipate heat, maintain battery shape under stress, and extend the overall lifespan of your investment.

Key Features

  • Powerful 50C Continuous Discharge Rating — This specification means the battery can safely deliver high current continuously without voltage sag, ensuring your aircraft maintains consistent performance throughout your entire flight and providing the responsive handling you need for aerobatic manoeuvres.
  • Protective Metal Alloy Outer Sheet — The durable aluminium alloy exterior doesn't just look professional; it actively dissipates heat away from the internal cells, helps the battery maintain its shape under the stresses of flight, and significantly increases the overall durability and longevity of the pack.
  • Compact Size for Micro and Mini Aircraft — At just 1.93 inches long and weighing only 85 grams, this battery fits perfectly into the tight airframe spaces of most 4S-powered micro and mini RC aircraft, minimising weight penalty whilst delivering maximum power.
  • Factory-Installed JST Connector — The standard JST-RCY connector comes pre-soldered and tested, eliminating the need for connector modifications and allowing you to start flying immediately after charging.
  • 4-Cell 14.8V Configuration — Four lithium polymer cells in series provide the 14.8V nominal voltage ideal for high-performance brushless motor systems commonly found in modern RC aircraft.

Technical Performance

The Spektrum 450mAh 4S 14.8V battery represents a carefully engineered balance between capacity, power delivery, and weight. The 450mAh capacity provides adequate flight time for micro and mini models whilst keeping the overall package weight to just 85 grams—crucial for maintaining the performance characteristics and flight envelope of lightweight airframes. The 50C continuous discharge rating translates to a maximum continuous current delivery of 22.5 amps (450mAh × 50C = 22,500mA or 22.5A), sufficient to power modern brushless outrunner motors commonly used in RC aircraft. The maximum charge rate of 5C (2.25A) means you can fully recharge from empty in approximately 12 minutes, allowing for rapid turnaround between flights. The protective metal alloy sheet construction isn't merely aesthetic—it serves the dual purpose of thermal management and structural integrity, helping maintain cell alignment under the vibration and acceleration loads experienced in flight. The JST connector is the standard found on most Spektrum aircraft systems, ensuring compatibility with a wide range of receivers and flight controllers used in modern RC hobby aircraft. This battery does not feature Spektrum Smart Technology, which means it lacks integrated telemetry capabilities, but this also means it's compatible with any standard balanced charger equipped with 4S LiPo charging profiles. The soft-case design keeps weight minimal whilst the external protection maintains shape and durability throughout extended use.

Frequently Asked Questions

  • Is this battery suitable for beginners to RC aircraft? — Yes, this Spektrum battery is suitable for pilots of all experience levels. The factory-installed JST connector means no soldering or connector work is required, making it beginner-friendly. However, you will need experience with LiPo battery safety and charging procedures. Always use a proper 4S LiPo balance charger, never leave charging batteries unattended, and store in a safe location.
  • What aircraft can use this 450mAh 4S battery? — This battery is designed specifically for micro and mini RC aircraft with 4S power systems. Check your aircraft's specifications to confirm it accepts 4S 450mAh batteries and features a JST connector. Common applications include small foam aircraft, park flyers, and lightweight training models.
  • How long will this battery power my RC aircraft? — Flight time depends on your specific aircraft, motor efficiency, and flying style. Generally, a 450mAh battery in a micro or mini aircraft provides 5-15 minutes of flight time, though aggressive aerobatic flying will reduce this. Consult your aircraft manual for estimated flight times.
  • What does the 50C discharge rating mean? — The 50C rating indicates this battery can safely deliver 50 times its capacity in continuous current. For this 450mAh battery, that equals 22.5 amps. This high discharge rating ensures your motor receives consistent power even during demanding manoeuvres without voltage sag.
  • How do I charge this battery? — Use a dedicated 4S LiPo balance charger with a maximum charge rate of 5C (2.25A). Always charge to a balanced state on all four cells, never overcharge, and charge in a safe location away from flammable materials.
  • Does this battery have Spektrum Smart Technology? — No, this battery does not feature Spektrum Smart Technology. It's a standard LiPo battery compatible with any 4S balance charger. The benefit is lower cost and compatibility with a wider range of charging equipment.
  • How much does this battery weigh? — This battery weighs just 85 grams, making it ideal for weight-critical micro and mini aircraft applications where every gram affects performance.
  • What is the maximum charging speed? — The maximum safe charge rate is 5C, which equals 2.25 amps for this 450mAh pack. Charging at this rate should fully charge the battery in approximately 12 minutes.
  • Is this battery waterproof? — LiPo batteries are not waterproof and should never be exposed to moisture. If your aircraft ditches in water, recover the battery and allow it to dry completely before attempting to charge. Never charge or discharge a wet battery.
  • What makes Spektrum batteries reliable for RC aircraft? — Spektrum is a division of Horizon Hobby, a recognised leader in RC technology. Their batteries undergo rigorous quality control and are designed specifically for the demands of RC aircraft. The protective metal alloy casing and proven cell chemistry ensure consistent performance and longevity.
