Hey jr dr,
Be careful. 450 A is over 11C rate on a 40 Ah cell. Some types of cells will support that high rate, others will not. I've not used GBS, but do not think they would be a good choice for high rate discharge.
I'm not sure where the number 3.1 kw comes from. Are you mixing power and energy? But from your post #1, you should be looking for 30 kW.
