Hi, I've done a search and found numerous battery problems but none relating to my problem. I have a 2019 kenevo comp and my battery will not switch on. No lights, nothing. I rode it with 100% charge and used about 30%. As I was riding the next day I left the battery in the bike (usually remove it) and now it will not switch on. I've tried charging it but the green light remains on the charger indicating it's full. Has anyone had this happen before? Do I need a new battery?
