Support multiple batteries

Display status of the batteries per instance.

Out of the box the primary battery status will be displayed in the i3-bar. For some laptops that has multiple batteries e.g. ThinkPad, you want to have both batteries displayed. To do so, follow the steps:

  1. Stage your own i3 config file (tutorial), then open ~/.config/regolith/i3xrocks/config in your editor of choice.
  2. Find the line that pertains to the battery blocklet:
...
# Battery indicator
#
# Displays total percentage charge left of specified battery.
[battery3]
interval=30
# instance=BAT0
  1. List all the battery instances running on your machine by running:
ls /sys/class/power_supply/

# AC BAT0 BAT1
  1. Update the staged config file to have a new blocklet as such:
...
# Battery indicator
#
# Displays total percentage charge left of specified battery.
[battery3]
interval=30
instance=BAT0

[battery3]
interval=30
instance=BAT1
