I just fixed this on one of my scooters. While using Ninebot-Flasher I noticed the BMS was version 1.2.5. I updated internal and external BMS to 1.4.1 and the error is now gone. If the error returns I’ll let y’all know but it seems error 49 is a BMS error. FYI here is a link where you can find the BMS file:
