I confirmed just a minute ago. The LVC value does not change anything once you set the Nominal Voltage. Even though the value remains the same when 'read'... you will get an E-08 (low energy alarm) error message on the display if you try to use a 36v (even fully charged to 42v) or lower when programmed to 52v...
48v LVC switches to show the E-08 at around 40v...
So unless you do many other changes, the min voltage has no change.
Just to be clear, I believe what you are stating here is that is possible to setup the motor to use just about any battery voltage however you cannot change the range between the high and low voltage cutoffs. Thus you can use any battery you like, but you would have to reprogram the controller before switching batteries of different voltages (unless they are close, like a 52v battery and a 48v battery and you are ok without being able to use 100% of the 2nd battery's charge).
Since the controller allows some headroom (my 48v controller now allows up to 56.7v +/-), perhaps there is a way to program the controller for a "non existent" battery that lies between 2 voltages. Like instead of programming it for a 52v battery it can be programmed for a 50v battery. That would likely allow (using my experience as an example) a battery up to 58.8v which would just squeak by for a full charged 52v 14s battery, yet the low cutoff would probably still be great for a 48v 13s battery.
It is not perfect but perhaps it would be a little more helpful if we can choose a setting that falls between 2 battery voltages that will allow both those batteries to be utilized to their full capacity.
