Frequently Asked Questions

• Is the Spektrum Smart G2 Powerstage Air Bundle suitable for beginners? — Absolutely. This bundle is specifically designed for first-time pilots and complete beginners. The Smart Technology platform eliminates the confusing decisions and technical knowledge that traditionally intimidated new RC enthusiasts. Simply connect your battery to the charger and everything else happens automatically. There are no complex menus to navigate, no balance connectors to worry about misaligning, and no risk of incorrect charging settings. The system even manages itself between flights with automatic storage discharge, meaning you do not need to remember special pre-flight or post-flight procedures. This makes it ideal for family RC experiences where multiple skill levels might be using the same equipment.
• What is Smart Auto Storage Discharge and why does it matter? — Smart Auto Storage Discharge is a factory-programmed intelligent feature in Spektrum G2 batteries that automatically reduces battery voltage to a safe storage level of 3.90V per cell if the battery remains unused for 72 hours. Traditional lithium polymer batteries suffer from degradation if left at full charge, which is why RC pilots have historically needed to remember to discharge their batteries before storing them. The Smart G2 battery eliminates this chore entirely—the battery manages itself. You charge it, fly it, and if you do not use it for three days, it automatically adjusts itself to the optimal storage voltage. This results in longer overall battery lifespan, more consistent performance throughout the battery's service life, and complete peace of mind knowing your investment is being protected even when you are not thinking about it.
• What aircraft can use this Spektrum Smart G2 Powerstage Air Bundle? — This bundle is specifically designed as the perfect complement to RTF Basic aircraft including Blade, HobbyZone, and E-flite Ready-to-Fly Basic models. It is particularly effective with aircraft featuring Avian ESCs or other telemetry-capable electronic speed controllers with one-wire telemetry capability. The 11.1V 3S configuration and 850mAh capacity are optimised for the lightweight motors and efficient designs found in these platforms. The included IC3-to-IC2 adapter ensures compatibility across different Spektrum connector standards, allowing this bundle to work with a wide range of current and recent Spektrum aircraft models. If you are unsure whether this bundle is compatible with your specific aircraft model, consult your aircraft's documentation or contact RC Model Shop's knowledgeable team.
• How long does the S120 charger take to fully charge the 850mAh battery? — The S120 charger is rated at 20W maximum power output in its 1x20W configuration. With an 850mAh 3S battery, this typically translates to charge times of approximately 25-30 minutes from a completely empty battery. However, because Spektrum Smart batteries feature automatic storage discharge to 3.90V per cell, they rarely remain completely depleted before your next flight session. In typical usage, where you charge after each flying session and fly again within a few days, you will be topping up from a safe storage voltage rather than charging from completely empty, which can take even less time. The actual charge time depends on your USB-C power source quality and the battery's current state of charge, but the S120 is engineered for convenient, quick turnaround times between flights.
• What makes Smart Technology safer than traditional battery chargers? — Smart Technology builds safety into the system architecture rather than relying on user knowledge or correct button pressing. The battery's embedded microchip communicates with the charger, telling it exactly what charging current, voltage limits, and balancing requirements that specific pack needs. There is no opportunity to accidentally overcharge a cell or apply the wrong charge profile. The automatic cell balancing is monitored electronically throughout the charging process. Storage discharge is programmed at the factory and requires no user intervention. Balance connectors—a common source of reversed-polarity accidents in traditional LiPo charging—are completely eliminated in the Smart ecosystem. Additionally, by communicating with your aircraft's ESC through one-wire telemetry, the system can monitor battery health throughout your flight and alert you to any potential issues. This layered approach to safety is why Spektrum recognises Smart Technology as the easiest-to-use and safest battery charging technology available in RC.
• Can I use this charger with non-Smart batteries? — No, the S120 Smart Charger is specifically designed to work with Spektrum Smart batteries featuring the intelligent memory microchip. It is not compatible with traditional lithium polymer batteries. However, if you eventually expand your RC fleet to include multiple aircraft or additional batteries, you can use the same S120 charger with any other Spektrum Smart battery packs, creating a unified charging infrastructure. The Smart ecosystem approach means you can grow your RC involvement without needing to maintain separate chargers for different battery technologies.
• Is the included IC3-to-IC2 adapter necessary for my aircraft? — It depends on your specific aircraft model. Some Spektrum RTF Basic aircraft feature ESCs with IC2 connectors, whilst others use IC3. The adapter bridges this gap, ensuring compatibility even if your aircraft uses a different connector standard than the battery. If your aircraft features an IC3 connector, you can connect the battery directly without the adapter. If it features an IC2 connector on the ESC or receiver, you will need the included adapter. The bundle includes the adapter for maximum flexibility across Spektrum's aircraft range.
• What is included in the box and what else will I need? — The bundle includes the S120 USB-C charger, the 850mAh 3S Smart G2 battery, and the IC3-to-IC2 adapter. To get flying, you simply need a compatible RTF Basic aircraft (such as a Blade, HobbyZone, or E-flite model) and a USB-C power source to plug the charger into. The bundle is genuinely complete—there are no hidden purchases or additional items required. USB-C power adapters are widely available and many households already have them from phones or other devices, or you can charge via any USB-C power source including computers or dedicated USB chargers.
