If you clicked the wrong error code, go back to the Error Code Index.
Error 46 on a Ninebot ESX scooter is related to issues with the external battery being "overly discharged". This is similar to Error 19, but Error 45 and Error 46 are solvable.
Error 46 occurs when the external batteries are left for too long or somehow end up discharging lower than the BMS should normally allow for.
Attempt to charge the scooter, you may need to leave it on for some time before the BMS is able to reboot.
