I have a RR 5 2021 and wanted to test voltage and range since I only have the 5 bars meter, SO, Question is,,,  Fully charged I get 53.7 Volts, After working it in PA 4 and some throttle for 15 miles went down to 48.1 Volts. and bouncing from 3 to 4 bars, And idea on range and voltage?  Common sense tells me  the voltage should be lower than 48.1.
Thanks, Paul

Here ya go - a range of what your voltage to battery drain is .

I ran a test on my 2021 Rover 5, full throttle only on level roads. The graph is the result.  I also mapped voltage to meter readings using a variable power supply in place of the battery.

Capacity is expressed in terms of miles.  I got 20 miles out of a full battery, so each mile is about 5% of capacity. This varies a bit from the posted chart because the chart is likely expressing capacity in terms of coulombs remaining in the battery. Mine is a real-world chart for the Rover.

Your voltage reading is as expected.

Great explanations for a rookie gents! Thanks for the knowledge.
