Hi guys , this is a bit strange to me so any helpful advice is welcome . I have a front hub 1000w direct drive motor . My controller is a 36/ 48v and I have a 48v main battery and a 36v backup . This morning when I went to start my bike up , the lcd came on but showing flat battery . Both my batteries are fully charged with the lights coming on , so I presume its not a fuse issue . I have swapped both batteries and two controllers ,still the same . Why is the lcd coming on if the batteries are flat anyway ?
