Hey Aqua, my Ghost gets voltage sag as well. It doesn’t seem to affect anything that I notice or effects overall performance. Just really weird the way the voltage sag happens on my Ghost compared to my old ebikes. I still need to do some real world range and speed test one day. Riding to work would be perfect (14 miles each way) but I don’t think my knees would like that very much! Heck, borrow the Ghost if you want. See how it voltage drops compared to your escoot.
