Hi! I just purchased a used eBike, an American Flyer that's a few years old. It's a 48v system with a 750kW direct-drive hub motor. The bike runs at about 23mph at full charge, but speed drops to 20mph at three out of four bars on the battery meter and then down to about 15mph after that. It has a 48v 11.6ah rack-mount battery. I tested voltage at full charge: 54.6v. Haven't tested at lower charge levels yet and I'm not sure when it hits 48v or lower.
Question: Is this normal? Could the battery be worn and need to be replaced? From what I've read, the battery should drop to 48v at about 50% charge. If it drops to 48v before that, does that indicate a worn battery?
Thanks!
