for now, it's range is 1/3 of when i first got it. so instead of 12 miles range, i get about 4 miles.
i also noticed it charges up to "full" in 1 hour instead of about the original 3hours. what does that mean? maybe 2/3 of the cells are damaged and the BMS is smart to skip those damaged cells?
Could be just one bad cell. Bad cells have lower capacity, so they fill up and reach HVC faster, leaving the good cells way under charged.
Only way to know for sure is break the pack down and cycle test each cell.
