So the nature of electric vehicles is that performance will drop along with the voltage.
But what do you consider a good and bad performance retention rate? Has anybody ever compared and quantified data on this?
For instance, I have a board that tops out at around 25 MPH at 100% charge. When it reaches 50%, the top speed is closer to 22 MPH. At around 20%, I’m down to 18 MPH. Would that be considered ‘healthy’ numbers or would it suggest that the cells I’m using probably aren’t the best?
Is there a theoretical way to predict performance drop-off based on, say, a discharge capacity test as seen here:
