Hi All ! I was wondering if anyone can refer me to a site or help me with my velomini 3. I just got a used velomini 3 the powers up, throttle works, pedal assist works, but cuts off after 10 minutes of riding and won't power back up. after an all night charge, I get 28.4 volts at the battery. After about 10 minutes I could get it to power back up, but all the power lights go low, and dim on a slight hill. Thanks in advance !!
