Based on your comment, can we make the assumption that 40C (40A) batteries delivers well above average 22A. That's all you need? Anything above would be a waste since Motor + ESC can not draw that much power?!

Is my assumption flawed? Just trying to understand the physics behind this.

From the examples listed above, if your motor maxed out at 130A current draw, it might only draw 15A going down the straight.

As an example, a 6 minute run for me in 17.5 TC at the Carpet Nats used about 2200mAh (or 2.2Ah). Since it was a 6 minute run (1/10 of an hour), the average discharge rate was approximately 22A (2.2Ah / 0.1h) = 22A
