Overview

Drivers and pilots enjoy even more Smart advantages when using Spektrum Smart G2 50C 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 IC2® 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.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!

Note: G2 batteries require the use of a Spektrum Smart Charger. Update your Spektrum Smart Charger for all the latest advancements in Smart Technology.

Frequently Asked Questions

  • What is the difference between Smart G2 and regular LiPo batteries? — Smart G2 batteries feature integrated microchip technology that stores comprehensive battery data, automatic storage voltage discharge, and one-connection IC2 charging without balance leads. Regular LiPo batteries lack these intelligent features and require manual charging parameter setup and separate balance lead connections. Smart G2 batteries effectively manage themselves, making them far superior for long-term reliability and ease of use.
  • Do I need a special charger for this Spektrum Smart G2 battery? — Yes, a Spektrum Smart Charger is required to fully utilise this battery's capabilities. When you connect the battery to a Smart Charger, it automatically uploads its unique parameters and health data, eliminating manual setup. The charger then applies optimal charging algorithms specific to this battery's condition and history.
  • What does the 50C discharge rating mean? — The 50C rating indicates the battery can safely deliver a continuous current of 50 times its capacity (810mAh). This equals approximately 40.5 amps of continuous current, providing the high power output needed for racing, aggressive flying, and demanding performance applications. Higher C ratings deliver more consistent voltage under heavy current draw.
  • Is this battery suitable for beginners in RC racing or flying? — Absolutely. The Smart G2 technology actually makes this battery ideal for beginners because it removes the complexity of manual charging setup. The automatic features, built-in safety protections, and comprehensive data logging make it more forgiving and easier to maintain than standard LiPo batteries. Beginners benefit from the peace of mind that comes with intelligent battery management.
  • How long does the battery take to charge? — Charge time depends on your charger's output capacity and the charge rate you select. The battery's integrated memory remembers your preferred charge rate, so it automatically applies the same setting every time you connect it. Spektrum Smart Chargers optimise charge time based on battery health and temperature.
  • What is the 3.90V storage voltage? — After 72 hours of inactivity, the Smart G2 automatically discharges to 3.90V per cell (7.80V for the 2S pack), which is the optimal voltage for LiPo storage. This safe voltage level minimises cell stress during storage and maximises the battery's lifespan. You can customise this auto-discharge setting if needed.
  • Can I use this battery with other RC brands' chargers? — This battery is specifically engineered for Spektrum Smart Chargers to enable its intelligent features. Whilst it may be manually charged with other compatible LiPo chargers, you would forfeit all Smart G2 automatic functions, data upload capabilities, and optimised charging algorithms. For best results and safety, use with a Spektrum Smart Charger.
  • What does the error log feature do? — The integrated microchip logs any over-charge, over-discharge, or over-temperature incidents. This diagnostic history helps you understand the battery's treatment and condition, allowing you to assess whether it remains suitable for your specific RC application or if it needs retirement.
  • Is the IC2 Device to EC2 Battery Adapter included? — Yes, the package includes an adapter allowing the IC2 connector to work with EC2-compatible equipment, expanding compatibility across your RC collection and enabling use with different platforms.
  • How much runtime should I expect from 810mAh capacity? — Runtime varies based on your RC vehicle's current draw, which depends on motor, ESC settings, and driving style. Generally, 810mAh provides 15-30 minutes of active flight or driving time, making it ideal for small-scale RC vehicles and aircraft. Multiple batteries allow extended session duration.
