Bosch Powertube 500 allmost impossible rebuild

[@ElectronicMechanicFinland]

new. Battery is now coming and More bms investigstigation videos coming up. i gave gained in my hands two more Power tubes and trying to figure out are they fixable. stories in internet tells that if bms is separated from Battery pack it will lock and erase itself but lets try figure out what really happens

[@lukasschmidt4902]

did you find out if thats the case? did it lock itself?

[@ElectronicMechanicFinland]

They are really bad. Voltage regulator fails and sends full bat voltage on canbus controller and main microcontroller. But cells are re-usable

Butcher or not but still most off time things gets fixed. I have no tools or knowlage to perform well with batteryes and bosch are making any refurb nearly impossible because software bricking and handshake protocol. If you have solution to re program bosch bms please share it. There is thousands off people who are seeking solution to unbrick batteryes . And thanks for your feedback it helps me to create content what might be helpful or intersing for internet
