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 30C LiPos are ready to fit into your RC Aircraft for better performance, power, and reliability.
