Overview
Drivers and pilots enjoy even more Smart advantages when using Spektrum™ Smart G2 50C LiPo batteries to power their vehicles. New "Generation 2" features make these LiPo packs — featuring a 50C continuous discharge rating for high performance and longevity — 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 50C 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 50C 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 50C 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 this Spektrum Smart G2 battery? — Yes, this battery requires a Spektrum Smart charger to function properly. The battery communicates directly with Smart chargers through the integrated microchip in the IC5 connector, automatically uploading its charging parameters and health information. This is not compatible with standard balance chargers or older charger models. The Smart charger requirement ensures your battery receives the optimal charging profile and that all safety features work correctly.
- Can I use this battery with my existing RC car or aircraft? — The IC5 connector is backwards compatible with EC5-style connectors, so if your RC vehicle has an EC5 connection, you can use this battery directly. However, you must have a Spektrum Smart charger to charge it. If your vehicle uses a different connector type (such as XT60, Deans, or other standards), you will need an appropriate adapter connector, though this is not ideal for long-term use due to potential connection resistance.
- What does the 50C rating mean and why is it important? — The C rating (discharge rating) is a measurement of how much current a battery can safely deliver. A 50C rating on a 5000mAh battery means it can safely deliver 250 amps of continuous current (5000mAh × 50C ÷ 1000 = 250A). This high rating makes the battery suitable for high-performance brushless motor systems, competitive racing applications, and demanding aerobatic flying. Lower-rated batteries would create voltage sag under such loads, reducing performance and potentially damaging the battery.
- How long will this battery keep me flying or driving? — Runtime depends on the power consumption of your specific RC vehicle or aircraft. The 5000mAh capacity and 22.2V voltage give you 111 watt-hours of total energy. A typical high-performance RC aircraft drawing 20 amps average current would provide approximately 15 minutes of flight time. RC cars with brushless motors might achieve 20-30 minutes of driving, depending on throttle use and terrain. These are estimates; actual runtime varies significantly based on your specific equipment and driving or flying style.
- Is this battery suitable for beginners? — This is a premium, high-performance battery designed for experienced pilots and drivers who understand LiPo battery safety and proper charging procedures. Beginners should consider whether they already own a Spektrum Smart charger and have experience with high-capacity LiPo batteries.

If you're new to RC, consult with experienced enthusiasts or visit your local RC Model Shop in Walsall for guidance.
- How does the automatic storage discharge work? — After 72 hours of inactivity (measured from the last time the battery was used), the integrated Smart G2 microchip triggers an automatic slow discharge to bring the battery down to 3.90V per cell storage voltage. This process can draw up to 1.5A and is approximately three times faster than previous-generation Smart batteries. This prevents the battery from sitting at full charge for extended periods, which degrades LiPo cell chemistry and reduces overall battery lifespan. You can change this automatic discharge setting through your Spektrum Smart charger based on your preferences.
- What makes this G2 version better than older Smart G1 batteries? — Smart G2 batteries feature several improvements over the original Smart G1 design. The storage discharge rate is three times faster (up to 1.5A versus slower rates on G1), meaning your battery reaches safe storage voltage more quickly. The IC5 connector design provides a more solid connection with higher heat resistance and easier installation. G2 batteries include thicker internal metal side plates for improved heat dissipation and better protection against cell puncture. The data logging is more comprehensive, and the overall charging and balance technology is more refined and reliable.
- Can I charge this battery at home? — Yes, you can charge any Spektrum Smart G2 battery at home using a Spektrum Smart charger connected to standard AC mains power or an appropriate DC power supply. The charger handles all the technical details automatically once you plug in the battery. However, always follow proper LiPo battery safety protocols: charge in a safe location away from flammable materials, never leave a charging battery unattended, and use a LiPo charging bag or safe charging container as an additional safety measure.
- What is the warranty on this battery? — Warranty information should be confirmed with RC Model Shop, but Spektrum Smart batteries typically include a manufacturer's warranty covering defects in materials and workmanship. Damage caused by incorrect charging, over-discharging, physical damage, or improper storage is typically not covered. Keep your receipt and registration documents safe.
- How can I tell if my battery is healthy? — Connect your battery to your Spektrum Smart charger and review the logged data. The charger will display charge cycle count, temperature history, and any recorded error events such as over-temperature, over-discharge, or over-charge incidents. A healthy battery should show low error counts and stable performance across charge cycles. If you see excessive errors or rapidly rising internal resistance readings, the battery may be approaching the end of its useful life.
