Speed decrease to 10mph at 75%

I noticed that there is a very large decrease in speed as i ride my board. My top speed is around 21-23 mph and like a 15-16 mile range, however after I ride maybe 2 miles (87%), it slows down to 16-17 mph. And after 4 miles (80%) down to 13 mph. And after 5 mies (78%) it’s down to <11 mph. AndI’m not sure whats causing this. Could be a setting in the VESC? Or maybe the batteries are shot? And it can’t be the BMS because its only wired for charging. Well thanks in advance for reading!
