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