Overview
Drivers and pilots enjoy even more Smart advantages when using Spektrum™ Smart G2 30C LiPo batteries. New "Generation 2" features make these powerful LiPo packs even simpler and safer to use together with your Smart charger.
For example, Spektrum™ Smart G2 technology makes it much easier to balance charge your LiPo batteries. Balancing information travels through the unique data wire of each Smart G2 battery's innovative IC3® or IC5® connector. As a result, only a single connection is needed — no separate balance lead is required.
Smart G2 batteries come from the factory programmed to discharge automatically to a safe storage voltage of 3.90V after 72 hours of inactivity. The benefits include longer battery life, better performance over the life of the pack, and the peace of mind that comes from knowing your Smart battery is maintenance-free. You can change the battery's Auto Storage settings based on your own preferences. G2 batteries also offer a storage discharge rate that's three times faster than the previous G1 Smart batteries.
Smart G2 30C soft-case LiPo packs also include thicker internal metal side plates. These plates improve heat dissipation and provide more protection for the cells against punctures during rough landings or in similar impact-prone situations.
As with other Smart batteries, you'll never have to set your own charging preferences for a Spektrum™ Smart G2 battery until you want to. When a Smart G2 LiPo battery is connected to a Spektrum™ Smart charger, its unique charging parameters and health information upload to the charger from the battery's integrated memory microchip. Through the charger you can view and set preferences such as charge rates, so all that's required to charge the pack is connecting it to your Smart charger. Smart technology takes care of the rest.
Spektrum™ Smart G2 30C LiPo batteries store a wide variety of essential information, including:
- Battery Brand
- Battery Type
- Battery Capacity
- Battery C Rating
- Individual Cell Voltage
- Battery Temperature
- Charge/Discharge Cycles
Spektrum™ Smart G2 LiPo 30C batteries also maintain an error log including the number of over-heat, over-discharge and over-charge incidents. This data can be helpful in assuring that the battery you've chosen is right for the application. Innovative Spektrum™ Smart G2 LiPo 30C batteries are so easy to use, they nearly take care of themselves. It's easy to achieve peak battery performance, reliability and longevity with Smart G2 technology!

Frequently Asked Questions
- Do I need a special charger for Spektrum Smart G2 batteries? — Yes, Spektrum Smart G2 batteries require a Spektrum Smart charger. Whilst you can technically charge them with standard LiPo chargers if you have a 3S balance connector adapter, you will lose all the intelligent features including automatic parameter upload, health monitoring, and the data logging benefits that make Smart batteries superior to conventional LiPo packs. A Spektrum Smart charger is essential to experience the full advantages of the Smart G2 system.
- What makes Smart G2 batteries better than regular LiPo batteries? — Smart G2 batteries eliminate the need for separate balance leads, automatically manage storage discharge, remember your charging preferences, and continuously log health data. Regular LiPo batteries require manual configuration of charge parameters and separate balance connectors. The Smart system essentially takes care of battery maintenance automatically, extending lifespan and improving reliability.
- How long will the 1300mAh capacity provide flight time or run time? — Flight or run time depends on your specific RC application's power draw. A lighter RC aircraft or small drone might achieve 15-25 minutes of flight time, whilst a lightweight RC car might run for 20-45 minutes depending on throttle usage. The 1300mAh capacity makes this battery ideal for smaller scale RC models rather than high-performance racing applications requiring larger capacity packs.
- Is the Smart G2 suitable for beginners? — Absolutely. In fact, Smart G2 batteries are particularly beginner-friendly because they eliminate confusing manual charging setup. You simply connect the battery to your Spektrum Smart charger, and the battery tells the charger exactly how to charge itself safely. The automatic storage discharge means you don't need to remember to store your battery at the correct voltage. For new RC pilots and drivers, the Smart system removes a major source of confusion and reduces the risk of over-charging or storage damage.
- Can I use this battery with my existing non-Smart charger? — Technically yes with an adapter, but you'll lose all Smart features. The battery won't communicate with the charger, you won't get health data uploads, and you'll need to manually configure charging parameters. It's like using a smartphone with a feature phone charger—technically possible but missing all the intelligent benefits.
- What is the 30C rating and what does it mean for my RC? — The 30C rating indicates the continuous discharge rate. Multiplying the 1300mAh capacity by 30 gives 39 amps maximum continuous discharge. This is substantial current suitable for brushless RC motors in vehicles and aircraft. If your application draws more than 39 amps continuously, you'd need a battery with a higher C rating. For most recreational RC flying and driving, 30C is more than adequate.
- How does the auto storage discharge work? — After 72 hours without any charging or discharging, the Smart G2 battery automatically discharges itself to a safe storage voltage of 3.90V per cell (11.7V total for this 3S pack). This is three times faster than previous Smart G1 batteries, taking roughly 2-3 weeks to complete. This automatic function prevents the battery damage that occurs when LiPo cells remain at full charge for extended periods, dramatically extending overall battery lifespan.
- What is the difference between Smart G2 and the older Smart G1 batteries? — Smart G2 represents the second generation of Spektrum's Smart technology. Key improvements include three times faster storage discharge rates (completing full discharge in weeks rather than months), thicker internal metal side plates for better protection and heat dissipation, and enhanced overall durability. Both generations work with Spektrum Smart chargers, but G2 offers superior convenience and battery longevity.
- Can I use the IC3 connector with EC3 connectors? — Yes, IC3 connectors are backwards compatible with EC3 style connectors, meaning you can connect this battery to RC devices designed for EC3 connectors. However, the Smart data communication only works with chargers that support IC3 or IC5 connectors.
