Happy birthday to everyone and many achievements in life !
For more than a month I have a problem with my e-scooter, it cuts off the current when the e-scooter reaches 48.6v 4/5 lines (60%), I checked the battery and each series, I found some mismatched voltages, much too low. Some was 4v and some was 3.46v. I tried to balance them up to 3.7 - 3.8v and I have the same problem.
My question is, could be there a blown fuse somewhere in the display or other components? The controller has been changed and I also change the BMS but the new BMS does not charge the battery, probably because of the voltage differences. What do you guys think ?
