i3blocks Dual Battery Status

A simple script to display the battery percentage and status (charging, discharging, or low battery) in your i3blocks status bar. Supports systems with one or two batteries.

🔋 Features

• Interactive button allowing user to check the remaining battery time by left-clicking.
• Displays the combined battery percentage for systems with multiple batteries.
• Shows charging status with an icon (⚡).
• Alerts for low battery levels with an icon (🔋).
• Works seamlessly with i3blocks on Arch Linux or any Linux distribution using i3wm.

📋 Prerequisites

• Linux system with i3wm and i3blocks installed.
• Battery information available under /sys/class/power_supply/BAT0 and /sys/class/power_supply/BAT1 (or only BAT0 for single-battery systems).

🛠️ Installation

1. Clone the Repository

git clone https://github.com/dawidadamowicz/i3blocks-dual-battery-status.git
cd i3blocks-dual-battery-status

2. Install the Script

Copy the battery_status.sh script to your i3blocks configuration directory:

mkdir -p ~/.config/i3blocks
cp battery_status.sh ~/.config/i3blocks/
chmod +x ~/.config/i3blocks/battery_status.sh

3. Update i3blocks Configuration

Add the following block to your i3blocks configuration file (usually located at ~/.config/i3blocks/config):

[battery]
command=~/.config/i3blocks/battery_status.sh
interval=30

4. Reload i3blocks

Reload i3blocks to apply the changes:

pkill -SIGRTMIN+10 i3blocks

🖱️ How It Works

• The script checks the battery status and capacity for /sys/class/power_supply/BAT0 and /sys/class/power_supply/BAT1.
• If multiple batteries are present, it calculates the average percentage.
• Icons are displayed based on the status:
  • ⚡ for charging.
  • 🔋 for low battery (≤20%).
• Outputs the battery percentage and icon in the i3blocks bar.

Example Output

Status	Output
Charging	⚡ 65%
Low Battery	🔋 18%
Discharging	54%
No Battery Found	No battery
