User Notes
This version has several issues.
Primarily it will go into charging mode when using regen braking which will shut off the headlight or change the mode.
This version was pulled almost immediately after being published and BMS 1.5.5 was released to fix it, though it would not.
This behavior can be dangerous so this version is not recommended to run.
