SBM-01 high precision battery monitor

The super-lock must not be confused with the setup-lock (Function F20).
The big difference between the two is that anybody can disable the
setup-lock, even without communication between SBM-01 and PC. The
setup-lock is used to avoid accidental altering of the Function values.
While the super-lock can only be (de-)activated via the PC-link using a
unique password. The super-lock feature is primarily meant for warranty
purposes.
