Battery status not working when more than 1 laptop battery exists

[spez1998]

PROBLEM:
On laptops with more than 1 battery (e.g. Thinkpad T480), get_battery() function inside tools.py will not populate battery info as battery_count = len(glob.glob("/sys/class/power_supply/BAT*")) will always evaluate as >1 and if battery_count <= 1: branch is never entered.

Potential solutions:

1. Provide users with the option to select which battery to display capacity of. Perhaps functionality can exist to show the next battery's capacity when the default battery runs to 0%.
2. Automatically display the currently discharging battery's power. This information is available via /sys/class/power_supply/BAT*/status.

It seems that psutil.sensors_battery() always defaults to showing the stats of the internal battery. So as an initial fix, the check for battery_count >= 1 could be removed. However, I could envision something like this so that get_battery() always gets the currently discharging battery info:

def get_battery():
...
    batteries = glob.glob("/sys/class/power_supply/BAT*")
    for battery in batteries:
        status = sp.run(["cat", f"{battery}/status"], capture_output= True).stdout.decode("utf-8") # Or something more efficient
        if status == "Discharging":
            # Run rest of get_battery() logic
