Spektrum Smart G2 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 are 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. The updated G2 performance batteries feature an all in one connector that eliminates the need for a balance connector, as the balance process is done through the charger and the battery connector. The smart batteries also come programmed from the factory to self discharge to a safe 3.90V per cell after 72hrs of inactivity. All of the functions and features placed in this battery are intended to supply the user with a powerful and safe lithium battery.
