You have to reduce total voltage to 32-36v (with 12s under load at full speed). A heavy truck sucks 800-1500 Watts at those speed levels (above 40mph) depending on the surface you run it. Meaning you will need up to 45A. At this amp level voltage of A123 cells drops down to 2.8v per cell.

So 33v will give you a more realistic speed and rpm under load.
