Trying to determine battery halfway point

[lenberman]

I recently bought a Veego Semi-Fat and after 200 miles I am thoroughly satisfied. I am trying to determine the point where my battery is halfway depleted. I have a 36V motor and a 13AH battery that charges to 42V which provides voltage to the cutoff on the BMS which is 29V (according to mfg). Since my LED readout indicates voltage would I be correct in figuring that when I reach 36.5 (42-6.5=36.5) I am halfway depleted? My confusion has to do with all the WH left in the battery below the 29V cutoff. Thank you, Len

I'd not let the battery go down to 29V. That's 2.9V per cell. That will be hard on the battery.
