Battery Gauge Inspiration(Help), What values do you use for SOC, Voltage, Temp

Looking for some inspiration(help) on battery gauges for a 12V 100AH Lifepo4 battery. I’ve seen examples such as the attached and looking for what values are used for each segment? Is there a “best practice” value?

This is what I use for my 12V battery voltage in ApexCharts:

    color_threshold:
      - color: "#e45e65" # red
        value: 15
      - color: "#e0b400" # yellow
        value: 14
      - color: "#0da035" # green
        value: 12
      - color: "#039BE5" # blue
        value: 11.5

For the SOC of a float battery I’d recommend:

100 → 80 green
79-50 → yellow
49-0 red or blue

For a deep cycle battery:

100 → 50 green
49-20 → yellow
19-0 red or blue

For temperature look up the datasheet of your battery.

As for battery level color:
note that an icon color is defined in HA as:

  if (value >= 70) {
    return "--state-sensor-battery-high-color";
  }
  if (value >= 30) {
    return "--state-sensor-battery-medium-color";
  }
  return "--state-sensor-battery-low-color";

So it probably makes sense to use same thresholds (although I would choose values like 34, 67).
