Hey everyone, I wanted to share my recent experience with the BMS Battery Cells Card in Home Assistant. This custom Lovelace card has been a game-changer for monitoring my battery storage system! 
What It Does
The card provides a clear, customizable view of individual cell voltages, which is crucial for maintaining the health of my battery setup. It supports multiple layouts, from bar charts to detailed tables, making it super flexible for different preferences.
My Setup
I use a Victron battery system, and this card has helped me keep an eye on cell balancing and drift. The detailed view even includes live history graphs for total voltage and cell drift, which is fantastic for long-term monitoring.
Features I Love
- Interactive Elements: I can toggle charge, discharge, and balance modes directly from the card. No need to navigate through multiple menus!
- Customization: The UI editor makes it easy to tweak thresholds and layouts without touching any YAML.
- Statistics: Real-time stats like total voltage, current, and power give me instant insights into my system’s performance.
How I Installed It
- HACS Installation: I added the GitHub repository through HACS and installed the card in a few clicks. No manual file editing needed!
- Configuration: I set up the card with my battery entities and adjusted the voltage range to match my system. The card was live in minutes!
Tips for Others
- Entity Setup: Make sure your BMS provides the necessary cell voltage entities in Home Assistant. This card relies on them to work its magic.
- Updates: Keep an eye on the GitHub repo for updates. The developer is actively improving it, and new features are always exciting!
Overall, this card has elevated my battery monitoring game. If you’re into renewable energy or have a battery storage system, I highly recommend checking it out!
