Hi all, I have adapted the battery script to Libra Colour :
- found correct path
- commented out empty lines (they generate error messages on Libra Colour, weird ?)
The result is attached.
Here is the script :

# Battery Statistics Calculator 1.1 (2024-05-25) by Aleron Ives
#
# This script calculates battery statistics for the Kobo Libra 2.
# (adapted for Libra Colour : see v_pct")
# (adapted for Libra Colour : "bd71827_bat" instead of "battery" in path)
# Check the contents of /sys/class/power_supply/ if you use a different
# model to ensure that the statistics you want to track are available.
#
# You can use NickelMenu to invoke this script like so:
# menu_item :main :Battery :cmd_output :500 :/mnt/onboard/.adds/battcalc.sh
#
# Gather the necessary statistics
#
meter=$(cat /sys/class/power_supply/bd71827_bat/capacity)
v_now=$(cat /sys/class/power_supply/bd71827_bat/voltage_now)
v_min=$(cat /sys/class/power_supply/bd71827_bat/voltage_min)
v_max=$(cat /sys/class/power_supply/bd71827_bat/voltage_max)
c_now=$(cat /sys/class/power_supply/bd71827_bat/charge_now)
c_full=$(cat /sys/class/power_supply/bd71827_bat/charge_full)
c_dfull=$(cat /sys/class/power_supply/bd71827_bat/charge_full_design)

# Format the statistics
