The rest of the parameters are based on the Cell you use.
Let's use Samsung 25r cells for example.
Max. continuous discharge current: 20A
Safe pulse discharge ratings: 95A < 0.5 sec, 65A < 1 sec, 40A < 5 sec, 30A < 6 sec
Nominal capacity: 2500 mAh
Nominal voltage: 3.6 V
Discharge end voltage: 2.5 V
Charging voltage: 4.20 +/- 0.05 V
Standard charging current: 1.25 A
So if you put 11 Cells in Parallel you will get 27.5Ah, and then put 20 rows of cells In Series (72V) for a total of 220 Cells.
And now you can calculate your battery specs simply by multiplying every value by 20 (Cells in series)
Discharge cutoff 50V (I would recommend 60V though)
Nominal Voltage 72V
Charge cutoff 84V
As for the other parameters, those will be multiplied by 11 (Cells in Parallel)
Max Cont. Discharge current 220A
Discharge current 6 sec. 330A
Nominal Capacity 27.5Ah
Standard Charging current 13.75A
