Smart Battery Technology

When connected to a Spektrum Smart charger, a Smart battery's unique parameters, health, and balancing information upload automatically from its memory microchip through the IC3® or IC5® connector's data wire. To charge and balance the pack, you simply connect it to your Smart charger. Safe charging begins automatically. Smart Auto storage discharge ensures a longer battery life.

 

Smart Auto Storage Discharge

Spektrum Smart G2 batteries practically take care of themselves. G2 batteries come from the factory programmed to automatically discharge to a safe storage voltage of 3.90V after 72 hours of inactivity. The results are longer battery life, better performance over the life of the pack and peace of mind that your Smart battery comes maintenance-free.

Technical Performance

The Spektrum Smart G2 Powerstage Air Bundle represents a significant leap forward in battery and charging technology for RC aircraft enthusiasts. At the heart of this system sits a carefully engineered 11.1V 3S LiPo battery with a 4000mAh capacity, delivering 44.4 watt-hours of energy in a compact, lightweight package measuring just 5.51 inches in length, 1.69 inches in width, and 0.94 inches in height, with a total weight of between 200-299 grams depending on exact packaging. The three-cell configuration (3S) provides the optimal voltage for Ready-to-Fly Basic aircraft equipped with standard brushless motors and 30A ESCs, whilst the 4000mAh capacity ensures sufficient flight time for multiple sorties before requiring a recharge. The battery's 30C continuous discharge rating and maximum 4A continuous discharge current guarantee smooth, responsive power delivery throughout the flight envelope, whether you're practising gentle turns with a flight trainer or executing more dynamic manoeuvres. The S120 charger delivers 20W of charging power through modern USB-C connectivity, capable of accepting input from virtually any USB power source found in modern homes and workplaces. With a maximum charge rate capability of 3-5 amps and preset 1C charging profiles (4 amps for this 4000mAh pack), the charger can replenish a depleted battery in approximately one hour, making it possible to enjoy back-to-back flying sessions throughout a day at the field. The battery's soft case construction provides adequate protection during transport and storage whilst maintaining a lightweight profile, and the 12 AWG wire gauge ensures efficient power delivery with minimal voltage drop during discharge cycles. The integration of thermal protection, charge protection circuitry, and low input voltage protection creates a comprehensive safety net that prevents common causes of battery damage and failure.

Frequently Asked Questions

  • Is the SPM Smart G2 Powerstage Air Bundle suitable for beginners learning to fly RC aircraft? — Yes, this bundle is specifically designed for beginner pilots who have just purchased Ready-to-Fly Basic aircraft. The Smart technology eliminates complex manual configuration, making it impossible to set incorrect charging parameters. Simply connect the battery and charging begins automatically with perfect settings every time. The integrated safety features including thermal protection, charge protection circuitry, and automatic storage discharge provide comprehensive safeguards against damage, making this an ideal choice for pilots new to RC flight who want reliable, maintenance-free operation.
  • How long does it take to charge the 4000mAh battery with the S120 charger? — The S120 charger can fully charge the 4000mAh battery in approximately one hour when using the standard 1C charge rate (4 amps). The battery's microchip automatically communicates the optimal charge rate to the charger, so you simply connect the battery and let the system handle all parameters. With USB-C connectivity, you can charge from any compatible USB power source including computer ports, wall adapters, or portable power banks, giving you flexibility in where and how you charge.
  • What aircraft models is this bundle compatible with? — This bundle is designed as the official completing component for Spektrum Ready-to-Fly Basic aircraft including Blade, HobbyZone, and E-flite models. The 3S 11.1V configuration with IC3 connector is standard for most RTF Basic aircraft. If you already own a specific aircraft, verify that it accepts 3S batteries with IC3 connectors and is compatible with 4000mAh capacity. The recommended pairing mentioned by manufacturers includes the E-flite Apprentice STS 1.5m and similar trainer-class aircraft.
  • What makes Spektrum Smart G2 batteries different from standard LiPo batteries? — Smart G2 batteries contain an integrated microchip that stores detailed information about the battery including voltage, capacity, cell count, and health parameters. When connected to a Smart charger, this data automatically uploads, eliminating the need to manually input settings. Additionally, Smart G2 batteries feature automatic storage discharge, which discharges to a safe 3.90V per cell after 72 hours of inactivity, significantly extending battery lifespan compared to standard LiPo batteries that can suffer from storage-induced damage. This makes Smart batteries virtually maintenance-free compared to traditional alternatives.
  • Does the S120 charger work with other batteries besides this Smart G2 pack? — The S120 charger is specifically designed to work seamlessly with Spektrum Smart batteries, which automatically configure all parameters through their integrated microchips. For maximum compatibility and safety, it is recommended to use this charger exclusively with Spektrum Smart batteries. Using non-Smart batteries with Smart chargers may require manual configuration and may not provide the same level of automatic safety optimisation.
  • How does the automatic storage discharge feature work and why is it important? — After the battery sits unused for 72 hours, it automatically discharges itself to exactly 3.90V per cell, which is the ideal storage voltage for LiPo battery longevity. Storing fully charged LiPo batteries can cause permanent damage to the cells, reducing performance and lifespan. By automatically maintaining the correct storage voltage, this feature means you can store your battery for weeks or months without worrying about degradation, and it will be ready to fly whenever you want to head to the field.
  • What is the warranty and support available for this bundle? — Spektrum products are backed by comprehensive manufacturer support including access to the My Spektrum website for product registration, firmware updates, and downloads. The bundle includes detailed instruction manuals in English, German, French, and Italian, plus access to the Spektrum Smart Batteries and Charger FAQ documentation. Refer to manufacturer documentation for specific warranty terms and conditions.
  • Can I use this battery with multiple aircraft? — Yes, the IC3 connector is the standard for RTF Basic aircraft, so this 4000mAh 3S battery can be used with any compatible aircraft that accepts 3S batteries with IC3 connectors. This makes it an excellent purchase if you plan to expand your RC fleet or own multiple trainer-class aircraft. The battery's 4000mAh capacity suits the majority of Ready-to-Fly Basic aircraft from 1.5m trainers to larger models.
