The voltage of the battery drops during discharge. As a result, you need to multiply the Ah capacity by the *average* discharge voltage in order to get at kWh. I think the average discharge voltage is around 375V, so that gives about 24.8kWh.BiggieJohn said:Notice the Ahr is 66.14. at full charge, 395V * 66.14Ahr = 26kw

Battery capacity is measured in kWh, not "Kw".BiggieJohn said:alozzy said:Maybe because not all the kWh are useable because the BMS prevents the cells from dropping below a certain voltage.
The old 24Kw battery had 22.5Kw usable.
I guess I need to do a full range test one of these days and make sure I have LeafSpy running the whole time to see how much gets used.
