How to achieve automatically open battery monitor at boot-up？

Step1: Modify code in batteryStatus.py

Comment out the following code by adding #

QIcon("battery_0.png"),
QIcon("battery_1.png"),
QIcon("battery_2.png"),
QIcon("battery_3.png"),
QIcon("battery_4.png"),
QIcon("battery_5.png"),
QIcon("battery_6.png"),
QIcon("battery_7.png"),
QIcon("battery_charging.png"), # 8

QIcon("battery_unknown.png"), # 10

Then add the following code to change the icon image from a relative path to an absolute path: (Notice: Please change 'elecrow' to your user name)

QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_0.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_1.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_2.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_3.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_4.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_5.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_6.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_7.png"),
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_charging.png"), # 8
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_alert.png"), # 9
QIcon("/home/elecrow/crowPi-L_BatteryStatus/battery_unknown.png"), # 10
