Gents, you just do not understand the tool you are using. Pack has the capacity you were promised, calculate it yourself. Set the % display, open the consumption tab. Now: (avg consumption * range remaining) / soc % in the form 0.5 for example (meaning 50% soc). The result is Watt hours in your pack.
The ‘used kWh’ display is just wrong. Forget it when it comes to these calculations.
On Batterygated cars this is not true. Tesla lowered volts which has a measurable kWh capacity decrease that limits you far below what was promised or ever tested by the EPA.
