Kt controller Low voltage cutoff

[Bitson555]

Is it possible to change the Low voltage cutoff point on a Kunteng "KT" controller?
Controller is 56 - 90 volt 50 amp model number KT56-90ZWSRKD-ff01.
I have a 52 volt battery pack so the controller will shut off power to motor under heavy load as volts dip to below 56.
I read somewhere that´s it´s possible to solder in new resistors on the PCB to alter the lvc circuit.
Is this possible? has anyone done this before and can you tell me how to do it ?!

If you are running a KT display, C12 will allow you to reduce the stock LVC by 2V. Otherwise you probably need to break out the soldering iron. There's a few discussions on the forum, including the KT OSF thread:

KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW)

Quick question... :) I am trying to test the 72v controller (56-90VDC) flashed with the open firmware with a 48v battery, but nothing happens. Still, in the parameter configurator, I put 0 and 255 for low and high voltage cutoffs, so I should not be bothered by any LVC... Is there a hard LVC...
