I have seven 6v batteries on my golf cart Will this work with 42v? Most all say meters are divisible by 12.

From the description it should power up and cover anything from 10V to 75 volts at least. Battery Capacity Voltage Meter with Alarm and External Temperature Sensor 0 - 179°F Temperature Monitor 12V 24V 36V 48V 60V 72V Acid Battery Lithium Battery Gauge Meter for Most Cars(Green)

I have a Battleborn LiFePO4 100Ah 12v which uses cylindrical cells, not prismatic cells, so there are 120 cells. What do I set the # of batteries to?

I did not put this into operation yet, but based on experience as I also have the same 80 cells cylindrical, I plan to set it as 1 battery. My max voltage is 13.8 -14.4v but considered a 12v battery.
