* '''LBO''': not a leveraged buy out! this is the '''Low Battery Output'''. By default it is pulled high to '''BAT''' but when the charger detects a low voltage (under 3.2V) the pin will drop down to 0V. You can use this to signal when its time to shut down or alert the user that the battery is low. There is also a red LED connected to this pin. | * '''LBO''': not a leveraged buy out! this is the '''Low Battery Output'''.
