I just quoted a large pack made from our team supplier's lowest cost "energy" Pouch cells rated at 30C continuous.
30C Line Up
10kWH would be $9,000 (450BHP) 3 boxes
20kWh would be $18,000 (900BHP) 6 boxes
30kWh would be $27,000 (1350BHP) 9 boxes
or about $900/kWH and $20/BHP
100C
Just for comparison a drag racing pack of my 6S 4.5Ahr 100C cells
$150 each 6PX15modules = $13,500
Boxes $2,250
Total $16,000
90X6X3.7X4.5=8.9kWh
250VX100*6*4.5=675kW or 905BHP
or about $1800/kWH but only $17/BHP
but, these obviously weigh half as much and are half the volume.
Fill in your pack requirements, multiply it out and see if that's in your budget.....
