The water tank level indicator display has broken in my van. There are four resistor-based sensors in the tank and I'd like to replace the display with an lcd or led type designed for batteries. Powering from the 12V nominal lead-acid or LiFePo4 battery (it needs to work for either) in the van I could replace the resistors on the tank as required for the display.
Assumed circuit is: Battery > Regulator > Tank Sensors > Level Indicator > Ground
The voltage of the battery will vary. How is:
Would a lead-acid level indicator with a more even voltage versus capacity curve or a Lithium one?

The voltage of the battery will vary. How is:
- power level regulated so the indicator measures tank resistors rather than battery voltage
- required tank resistors calculated
