Hi, I have been commuting 22 miles each way to my work every day. I average about 22 mph pedaling along with assist. But the last 2 days my batteries are cutting out. I haven't had any problems for over a month but now its cutting out. I am using 3 12v 12 amp hour batteries how do I check to see if one is bad?
Ive been having a great time commuting this way and feeling good at work all day but now that it is cutting out its a bit harder.. Can someone help me check to see which battery is bad?
