Only way I fix it, it vas remove the battery and charge the cell’s separately. You got to remove the sticker hiding the battery board, and charge the cell, by cell with 5v from any usb charger. The problem was; battery drained too much and motherboard was unable to detect any battery hooked to the system

Mine also stops working but it’s a firmware issue. Recently I found out, when I cut out the power by disconnecting the battery from a 2015 controller and plugged back in everything works like a charm until I reboot or shut down the console. So I made a workaround. I drill a hole on a controller and connect a switch to the battery. It was annoying the old way now I just hit the diy switch off and on and everything works fine  Regards
