Feature Overview
You'll never have to set charge preferences for a Spektrum Smart battery until you want to. When a Spektrum Smart LiPo battery is connected to a Spektrum Smart charger, unique parameters and health of that Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can view and set preferences, such as charge rates, so that all you have to do to charge the pack every time is press the charger "Start" button. Smart technology takes care of the rest.
Every Smart LiPo battery is factory assembled with the next-generation IC3T or IC5T output connector that's conveniently compatible with older devices equipped with robust EC3T and EC5T connectors. You can use Smart Batteries with older systems, but only when connected to a Spektrum Smart device will all the benefits of Smart technology become obvious.
Spektrum Smart LiPo Batteries Store Unique Data, such as:
- Battery Brand
- Battery Type
- Battery Capacity
- Battery C Rating
- Individual Cell Voltage
- Battery Temperature
- Charge/Discharge Cycles
Spektrum Smart LiPo batteries also maintain an error log including the number of over-heat, over-discharge and over-charge incidents which can be helpful data in assuring that the battery you've chosen is right for the application. A Smart Battery uploads its charge parameters to a Spektrum Smart Charger automatically making charging as simple as pressing the "Start" button. The charge rate of every Smart Battery is customizable, allowing you to take full advantage of packs with faster charge ratings.
Spektrum Smart Receiver Packs are designed to provide optimal current to the most demanding receiver power systems and provides pilots and drivers all the benefits of Spektrum Smart Technology, all while remaining small and lightweight.

Key Features
- Spektrum Smart Technology — The integrated microchip stores vital battery parameters and communicates with Spektrum Smart chargers, eliminating the need to manually set charge preferences each time you charge. Simply press the start button and the charger automatically loads the correct settings, saving you time and reducing the risk of charging errors that can damage your battery.
- Integrated Memory Microchip — Each battery remembers and stores comprehensive data including battery brand, chemistry type, cell count, capacity, C rating, individual cell voltages, battery temperature, and the total number of charge and discharge cycles. This data-rich approach helps you make informed decisions about battery health and suitability for your specific RC applications.
- Error Logging and Health Monitoring — The battery maintains a detailed error log tracking over-charge, over-discharge, and over-temperature incidents. This valuable diagnostic information helps you understand how your battery has been used and whether it remains suitable for your RC car, aircraft, or boat, ultimately extending the lifespan of your equipment.
- IC3 Connector with EC3 Compatibility — The next-generation IC3 connector features improved design with a more solid connection, higher heat resistance, and effortless installation. Importantly, it remains fully backwards compatible with existing EC3 connectors, allowing you to use this battery with older RC systems without requiring adapter cables or connector modifications.
- Smart Discharge Function — When programmed with a Spektrum Smart charger, the battery automatically discharges itself to a safe storage voltage after a period you select (between 12 and 240 hours). This prevents the battery from sitting fully charged for extended periods, which can degrade lithium cells and reduce overall battery life expectancy.
- Universal Receiver Compatibility — Engineered specifically to provide optimal current delivery to receiver power systems, this battery works with a wide range of receiver configurations and receiver types across different RC platforms, making it a versatile choice for RC car, aircraft, and boat enthusiasts.
- LiFe Chemistry Advantages — LiFe (Lithium Iron Phosphate) batteries offer superior safety characteristics compared to LiPo chemistry, with lower fire risk and more stable discharge curves. This makes them particularly suitable for receiver applications where consistent, reliable voltage is essential.
- Servo Connector Discharge Lead Included — The battery comes with a standard servo connector discharge lead (3.5 inches / 90mm long), providing added convenience for storage discharge and general connectivity without requiring additional purchases or adapters.
- User-Customisable Charge Rates — You can adjust the charge rate of this battery to take full advantage of its 1.5C maximum charge rating, with the charger remembering your preference for next time. This flexibility allows you to balance charging speed with battery care according to your schedule and preferences.
- High Discharge Rating — With a 15C continuous discharge rating, this 2200mAh battery can deliver substantial current to power demanding receiver systems with multiple servos, telemetry modules, and other accessories without voltage sag or performance degradation.

Frequently Asked Questions
- What makes Spektrum Smart Technology better than standard receiver batteries? — Spektrum Smart batteries communicate with Smart chargers through an integrated microchip, automatically uploading battery parameters and charging preferences. This eliminates the need to manually program charger settings each time, saves you time, and reduces charging mistakes. The batteries also monitor their own health status, tracking charge cycles, temperature events, and error conditions, giving you detailed information to optimise maintenance and replacement schedules for your RC car, aircraft, or boat.
- Is this battery compatible with my existing RC equipment? — Yes. The IC3 connector used on this battery is fully backwards compatible with the older EC3 connector standard. This means you can use the battery with RC systems equipped with EC3 connectors without requiring adapters or modifications. For best results and to access all Smart Technology features, connect the battery to a Spektrum Smart charger.
- How long will this battery power my receiver system? — Runtime depends on the specific demands of your receiver, servos, and other installed electronics. The 2200mAh capacity is substantial for receiver applications and will easily provide several hours of operation for typical systems. The battery's 15C discharge rating ensures it can handle the current demands of multiple servos and digital receiver equipment without voltage sag.
- What is Smart Discharge and why do I need it? — Smart Discharge allows the battery to automatically discharge itself to a safe storage voltage (between 1.5V and 3.0V per cell) after a time period you select—from 12 to 240 hours. This feature prevents the battery from sitting fully charged for extended periods, which can damage the chemical structure of lithium cells. Regular use of Smart Discharge significantly extends battery lifespan and maintains better performance over time.
- Can I use this battery with non-Spektrum chargers? — This LiFe battery can be charged with any quality 2S LiPo/LiFe charger, though you will lose the benefits of Spektrum Smart Technology. The battery's integrated microchip will only communicate with Spektrum Smart chargers. For full functionality, we recommend pairing this battery with a Spektrum Smart charger to automatically load all battery parameters and access advanced features like Smart Discharge.
- What is the difference between LiFe and LiPo chemistry? — LiFe (Lithium Iron Phosphate) batteries offer several advantages over LiPo batteries. They are inherently safer with lower fire risk, provide more stable and consistent voltage discharge throughout their runtime, have longer overall lifespan, and are less sensitive to temperature variations. These characteristics make LiFe particularly suitable for receiver applications where reliability and safety are paramount.
- Is this battery suitable for beginner RC enthusiasts? — Yes, absolutely. Spektrum Smart Technology actually makes this battery more beginner-friendly than standard batteries. The automatic charging settings eliminate confusion about proper charge rates, and the battery's comprehensive health monitoring helps beginners understand battery care. The 2200mAh capacity and 15C rating suit most receiver systems, and the included servo discharge lead simplifies storage preparation.
- How do I know when this battery needs replacing? — The battery's integrated microchip tracks numerous health metrics accessible through Spektrum Smart chargers, including over-charge, over-discharge, and over-temperature incidents. When these error counts become excessive, or when performance visibly degrades despite proper charging, it's time for replacement. The Smart Technology makes this assessment straightforward and objective.
