The battery practically takes care of itself, automatically discharging to a safe storage voltage after 72 hours of inactivity. For UK RC enthusiasts looking for a ready to use battery system that eliminates the maintenance headaches traditionally associated with LiPo batteries, the Spektrum Smart G2 delivers genuine peace of mind.
The 650mAh capacity and 30C discharge rating make this 2S pack suitable for a wide range of RC applications, from electric RC planes to lightweight RC cars and drones. The hardcase design provides robust protection during transport and storage, whilst the innovative IC2 connector simplifies your entire charging workflow. When paired with a Spektrum Smart Charger, this battery becomes part of an intelligent ecosystem that monitors every aspect of your pack's health and performance.
Key Features
- Smart G2 Integrated Microchip Technology — The battery contains an embedded microchip that stores essential information including battery brand, chemistry, cell count, capacity, C rating, temperature data, and complete cycle history, meaning your charger always knows exactly how to treat your battery safely and optimally.
- IC2 Connector with Single Connection Charging — Revolutionary IC2 connector technology eliminates the need for a separate balance lead entirely; balancing information travels through the connector's unique data wire, requiring only one simple connection to your Smart Charger for both charging and balancing.
- Automatic Smart Storage Discharge — Factory-programmed to automatically discharge to a safe storage voltage of 3.90V per cell after 72 hours of inactivity, this innovative feature dramatically extends battery life, maintains consistent performance across the lifespan of the pack, and removes the burden of manual storage management from the user.
- Faster Auto Discharge Rate — The G2 generation delivers automatic discharge at up to 1.5A, which is three times faster than the previous G1 Smart batteries, getting your battery to safe storage voltage more quickly whilst you're away from flying or driving.
- Comprehensive Battery Health Monitoring — The integrated error log tracks over-heat, over-discharge, and over-charge incidents, providing detailed insight into whether your battery is being operated correctly and helping you make informed decisions about battery care and application suitability.
- Simple and Quick Charging — Preset charge, discharge, and storage parameters are automatically relayed from the battery to your Smart Charger; simply connect the pack and intelligent charging begins automatically with no manual settings required, though you can customise charge rates if desired.
- Data-Rich Performance Tracking — Each battery saves vital statistics including number of charging cycles, discharge cycles, battery temperature during operation, and internal resistance, helping you understand and optimise your battery usage patterns.
- Durable Hardcase Construction — The protective hardcase shell safeguards the 650mAh cells during transport, storage and everyday use, reducing damage risk from impacts and providing peace of mind when carrying your battery to the flying field or track.
- Programmable Preferences — User-customisable settings allow you to adjust Auto Storage discharge timing based on your personal preferences, giving you flexibility whilst maintaining the safety benefits of automated battery management.
- Included IC2 to EC2 Adapter — The battery comes supplied with an IC2 Device to EC2 Battery Adapter, providing compatibility flexibility and ensuring you can integrate this battery into your existing RC setup even if you have legacy equipment.
Technical Performance
The Spektrum Smart G2 30C LiPo delivers robust technical performance across all the metrics that matter to RC enthusiasts. With a nominal voltage of 7.4V (two 3.7V LiPo cells in series), this 2S configuration provides the ideal balance of power and weight for applications ranging from small-scale RC aircraft to lightweight RC buggies and crawlers. The 650mAh capacity offers practical flight and runtime durations for typical RC use, whilst the 30C continuous discharge rating ensures sufficient current delivery for spirited flying or driving without thermal stress. The battery weighs just 59 grams and measures 58mm in length, 32mm in width, and 20mm in height, making it compact enough for weight-sensitive applications whilst providing robust real-world performance. The integrated balancer and internal adapter architecture eliminate the need for external balancing infrastructure, streamlining your charging setup and reducing clutter in your pit box or charger station. All of this engineering is housed within a protective hardcase construction that guards against physical damage during transport and storage, ensuring your battery arrives at the field ready to perform. The Spektrum Smart technology platform represents a genuine advancement in how modern RC batteries communicate with chargers and manage their own health, setting a new standard for convenience and reliability in the RC hobby across the UK and worldwide.

Frequently Asked Questions
- Do I need a special charger for the Spektrum Smart G2 30C LiPo battery? — Yes, a Spektrum Smart Charger is required to fully utilise this battery's intelligent features including automatic parameter upload, simplified charging workflow, and access to battery health data. Without a Smart Charger, you cannot charge this battery. The investment in a Smart Charger unlocks the complete Smart G2 ecosystem and transforms your charging routine.
- What makes the IC2 connector better than a traditional balance lead? — The IC2 connector integrates balancing information into the main power connector's data wire, eliminating the need for a separate balance lead entirely. This means only one cable connection is required instead of two, simplifying your setup, reducing clutter, and making the charging process faster and more intuitive. The single-connection system is particularly valuable if you charge multiple batteries in rotation.
- How does the automatic storage discharge work and why is it beneficial? — The battery is factory-programmed to automatically discharge itself to a safe storage voltage of 3.90V per cell after 72 hours of inactivity. This prevents the chemical stress that occurs when lithium cells remain at full charge for extended periods, dramatically extending overall battery lifespan and maintaining peak performance characteristics when you return to flying or driving. The automatic nature means you never forget this critical maintenance step.
- What information does the integrated microchip store? — The microchip logs battery brand, battery type, capacity (650mAh), cell count (2S), C rating (30C), individual cell voltages, battery temperature during use, complete charge cycle count, complete discharge cycle count, and importantly, an error log tracking any over-heat, over-discharge, or over-charge incidents. This comprehensive data helps you monitor battery health and make informed decisions about your packs.
- Is this battery suitable for beginners? — Yes, the Spektrum Smart G2 is actually excellent for beginners because it removes much of the complexity traditionally associated with LiPo battery management. The automatic charging parameters, simplified IC2 connector, and self-managing storage discharge eliminate common mistakes that new pilots and drivers make. The only requirement is that you must use a Spektrum Smart Charger, which is a sensible investment for anyone serious about the RC hobby.
- Can I use this battery in my existing RC car or aircraft? — The battery's 7.4V nominal voltage and 2S cell configuration makes it compatible with any RC equipment designed for 2S LiPo batteries. However, you must use a Spektrum Smart Charger to charge it. The included IC2 to EC2 Battery Adapter provides additional compatibility flexibility if you have legacy equipment with EC2 connectors.
- How long does it take to discharge to storage voltage? — The Smart G2 features a discharge rate of up to 1.5A, which is three times faster than earlier G1 Smart batteries. This faster rate means your battery reaches safe storage voltage more quickly, typically within 48-72 hours depending on usage patterns, allowing faster turnaround between flying sessions.
- What is the difference between G2 and G1 Smart batteries? — Generation 2 Smart batteries feature three times faster auto-discharge rates (up to 1.5A versus slower G1 rates), improved IC2 connector technology for simplified single-connection charging, and enhanced microchip capabilities for more comprehensive data logging and health monitoring. Both generations require Spektrum Smart Chargers, but G2 represents a genuine evolution in convenience and performance.
