I dont have enough time with the batteries under load to see the drop.
After a 14 mile ride with 4 miles of that being WFO, the pack had lost 1 volt.
According to my calculations, my pack fully charged (4.05 per cell @ 56.7v) if 60% is used would bring the cell voltage to 1.62 v per cell or 22.68v for the entire pack. I am not sure where the low voltage cut off would be on the Navitas 600amp controller. It is rated for 36-60vdc operation.
Should be good for any driving I am doing.
I have never had a cruise end due to battery charge, lead acid or other.
That does not include when I bought the cart with spent batteries

You need to read more on lithium battery math, 60% DOD is not the same as 60% Voltage.
A 60AH Nissan Leaf cell with a 90%DOD (10%SOC remaining) would have a cell voltage of
3.5v.
