Spektrum Smart Battery 

You'll never have to set charge preferences for a Spektrum™ Smart battery until you want to. When a Spektrum Smart LiPo battery is connected to a Spektrum Smart charger, unique parameters and health of that Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can view and set preferences, such as charge rates, so that all you have to do to charge the pack every time is press the charger "Start" button. Smart technology takes care of the rest. Our Spektrum Smart 50C LiPos are ready to drop into your RC car or boat for better performance, power, and reliability. These battery packs are a great upgrade for those looking to get more punch and off the line power on nearly any setup.
