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!

Smart G2 batteries are designed exclusively for use with Spektrum Smart chargers, and attempting to charge them with standard LiPo chargers will not access the advanced features such as automatic parameter detection and data logging. If you don't already own a Spektrum Smart Charger, you'll need to purchase one separately to use this battery.
- What does the 50C rating mean and why does it matter? — The 50C rating refers to the continuous discharge rate of the battery, meaning it can safely deliver current equal to 50 times its capacity continuously. With a 5000mAh (5Ah) capacity, this battery can deliver 250 amps continuously (5Ah × 50C = 250A). This high discharge rating ensures your RC vehicle receives consistent, unrestricted power during aggressive driving, rapid acceleration and demanding use, making it suitable for both racing applications and high-performance bashing without voltage sag limiting your vehicle's performance.
- How long will this battery last on a single charge? — Runtime depends entirely on your RC model's power draw, driving style and throttle usage. The 5000mAh capacity provides substantial energy for extended use, but a high-performance brushless motor system will drain the battery faster than a lower-powered setup. Typical runtime ranges from 15 to 25 minutes during aggressive driving, and potentially 30+ minutes during lighter use. Check your specific RC model's specifications and motor current draw for more precise runtime estimates.
- What is the auto-discharge feature and why is it useful? — Smart G2 batteries are factory-programmed to automatically discharge to a safe storage voltage of 3.90V per cell (11.7V total for a 3S battery) after 72 hours of inactivity. This automatic maintenance prevents the battery from being stored at full charge, which significantly extends overall battery lifespan and preserves performance over time. The feature can be customised based on your preferences, and it works entirely automatically — you don't need to do anything after your last use. This is especially valuable for UK RC enthusiasts who may not use their batteries frequently.
- Is this battery suitable for beginners? — The Spektrum Smart G2 is actually ideal for beginners because it simplifies battery management considerably. The automatic charging parameter upload and one-connection charging system eliminate common beginner mistakes like setting incorrect charge rates or damaging the battery through improper storage. However, beginners will need to invest in a Spektrum Smart Charger to use this battery, which is an additional cost compared to standard LiPo batteries. If you're new to RC and already have a different charger system, you might want to start with batteries compatible with your existing charger before upgrading to Smart G2 technology.
- What is IC3 and why does it matter? — IC3 is Spektrum's intelligent connector system that incorporates a data wire alongside the standard power connections. This data wire carries battery health information and charging parameters from the battery's integrated microchip to your Spektrum Smart Charger. The IC3 connector design provides a solid connection with high heat resistance and effortless installation. It's also backwards compatible with EC3 connectors, so if you have older RC equipment, you can use an adapter without compatibility issues. The IC3 connector is specifically designed for Smart technology and enables the single-connection charging that eliminates the need for separate balance leads.
- How does the integrated memory microchip work? — Each Spektrum Smart G2 battery contains an integrated memory microchip that stores detailed information about the battery including its brand, chemistry type (LiPo), capacity (5000mAh), C-rating, cell count, individual cell voltages, temperature data, total charge cycles, total discharge cycles, internal resistance and a comprehensive error log. This data is automatically uploaded to your Spektrum Smart Charger whenever you connect the battery, allowing the charger to automatically set optimal charging parameters. The error log also tracks over-charge, over-discharge and over-temperature events, helping you understand the battery's history and make informed decisions about its continued suitability for your application.
- What is the difference between G2 and G1 Smart batteries? — Spektrum Smart G2 batteries represent the second generation of Smart battery technology with several improvements over G1 models. Most notably, G2 batteries feature a dramatically faster auto-discharge function at up to 1.5A (three times faster than G1), meaning storage discharge to safe voltages happens in significantly less time. G2 batteries also include thicker internal metal side plates for improved heat dissipation and cell protection. Additionally, G2 technology is more user-friendly with simplified charging procedures. For new purchases, G2 batteries are the recommended choice as they represent the current standard in Smart battery technology.
- Can I customise the auto-discharge settings? — Yes, whilst Smart G2 batteries come factory-programmed with standard auto-discharge settings (3.90V storage voltage after 72 hours), you can customise these parameters through your Spektrum Smart Charger. The battery's integrated microchip remembers your custom settings, so once you configure the discharge preferences to suit your usage patterns, they automatically apply to every subsequent charging cycle. This flexibility allows you to optimise battery maintenance based on your specific requirements and how frequently you use your RC vehicle.
- What safety features does this battery include? — The Spektrum SPM 5000mAh 3S Smart G2 includes integrated charge protection circuitry that prevents overcharging, which is a common cause of battery damage and failure. Additionally, the battery's memory microchip continuously monitors temperature and logs any over-temperature, over-charge or over-discharge events. When connected to your Spektrum Smart Charger, the charger can detect these logged incidents and alert you to potential battery issues. The comprehensive data logging allows you to identify batteries that are experiencing problems and remove them from service before they fail catastrophically.
- Is this battery waterproof? — Whilst the battery itself has robust hard-case construction, LiPo batteries are not waterproof components and should not be submerged or exposed to water. The hard case provides good protection against moisture ingress during normal use, but you should avoid dunking the battery in water or exposing it to heavy rain. If your battery gets wet, allow it to dry completely before charging or using it again. For waterproof RC applications, ensure your vehicle's battery compartment seals properly rather than relying on the battery itself to be waterproof.
- How much does this battery cost compared to standard LiPo batteries? — Smart G2 batteries do command a premium over standard, non-Smart LiPo batteries because of their integrated microchip technology, automatic charge parameter detection, advanced data logging and superior build quality including thicker internal metal side plates. However, this premium is justified by the convenience, safety features, extended battery lifespan through automatic storage discharge, and elimination of manual charging setup. For UK RC enthusiasts who value reliability and ease of use, the investment in Smart G2 technology often pays dividends through reduced battery failures and maintenance hassles.
