## What it is
A custom Lovelace card for Home Assistant that displays battery levels from connected devices and entities. It offers filtering, sorting, and customizable display options for tracking battery states across a smart home.

## Use cases
- show battery levels of all smart home devices on one dashboard card
- monitor low battery sensors in Home Assistant
- group and sort battery entities by charge level
- customize battery card colors and icons based on state
- get alerted visually when device batteries need replacement

## When to choose
- you use Home Assistant with Lovelace dashboards and want a dedicated battery overview
- you need filtering, sorting, and bulk renaming of battery entities
- you want an actively maintained card with HACS support

## When to avoid
- you don't use Home Assistant or Lovelace
- you need battery history graphs rather than current state listing
- you want a generic entity card without battery-specific features
