Bought trance e 2 a month ago. I have done about 250 miles on it and mainly using eco plus mode on fairly flat paved/gravel trails as of now. I noticed my battery health now is 97% with 4 cycles of charge. If battery health continue in this pace it will reach 80% in less then a year. I do follow instructions on how to care, store and charge battery. Is it normal? What is your experience?
