Remove Motor Driver jumper to avoid current flowing from the batteries to the driver and thus corrupting the SD card.
Why does it happen?
After you turn off the controller from the power-bank the batteries will continue powering the system and returning current back to the controller. This current is small - about 700mA-800mA and is not enough to power the controller properly. But it is enough to corrupt the SD card image and you will have to burn it again.
