^^ cell capacity?
Price not specified - need to contact them
based on nominal voltage, need 130/3.2=about 41 cells in series to meet voltage requirement
Configuration: 24P 41S
Total number of cells: 984
Total Weight: 39.36kg
Max Voltage:
Nominal Voltage: 131.2 V
Min Voltage:
Nominal Capacity: 1.5Ah*24= 36 Ah
Minimum Capacity: 1.1Ah*24= 26.4 Ah ??
2000 charge cycles
Total volume [m^3]
height: 65mm
width: 18.2mm
volume of each cell: 16,910.0937 mm^3
Total volume = (volume of each cell)(# of cells) = (16910.0937)(984) = 16,639,532.2 mm^3 = 0.0166395322 m^3
Max volume: lwh = 41(18.2) 24(18.2) (65) = 21,186,110.4 mm^3 = 0.0211861104 m^3
Gravimetric Density [Wh/kg]
Calculating the power capacity (nominal) of the battery:
V * Ah = (3.2 V * 41) * (1.5 Ah * 24) = 4723.3 Wh
Gravimetric:
??
Wh/kg = 4723.3/39.36 = 120 Wh/kg
Volumetric density [Wh/L]
??
Wh/L = 4723.3/0.0211861104/1000 = 222.9 Wh/L
