Curious as to just how long a battery should last before it is expected to reach its end of life span (years)? My bike its almost 3 years old now and the battery seams good as new. Just anticipating how old they get before everyone is facing buying a replacement?
it all depends on the number charging cycles and how much throttle you use.
I got 7000 out of a battery before I started having problems. I burned the wiring because of too much current flowing. After repaired it was almost as good as new. But range for me is much lower because of have several hills I tackle.
I have two 2016 Radrovers with around 8000 miles between them. I have three batteries I rotate between the two rovers. Looks like my max range of 30-32 miles at PAS 2/3 is down to around 25-27 miles at PAS 2/3. Still works out because my max mileage on a ride is always under 20-22 miles. Only when I can't complete a norm ride is when I will consider replacement of the battery pack or the entire ebike.
The wife has an 2018 Radcity with only 1000 miles. I don't know if her battery pack has issues because she doesn't ride as far or as much.
Too cold and too hot can reduce battery performance
