Hi guys!
Recently I bought a used external battery for my Ninebot ES2 and probably it was used on a rental scooter, I´m receiving error 42 and I think its the rental firmware on it´s BMS.
My question is if there is a way to flash this battery directly through uart connection or using a ST-LINK v2.
Ninebot Rental External Battery Issue
Re: Ninebot Rental External Battery Issue
yes, it has an STM8L151 chip on it. This is a different ST cihip than the one on the dash and ESC though, and I have no idea where you would link up to on the PCB. Tried to take some pics of my PCB for you but i have shaky hands and shitty phone, will do better later http://imgur.com/a/LQp50htHi guys!
