Cheap PWM as LVD/HVD

Yesterday I was thinking about needing a High Voltage Disconnect.  These are much harder to find than Low Voltage Disconnects, where are everywhere on amazon and eBay.

Then I remembered the $8 cheapie controller from the shallow cycling experiment.  The LOAD output has a LVD and HVD setting.  Hmmmm…..

It’d be cheaper (and easier) to use one of these as a HVD.  It’s got a display for the config instead of arcane jumpers.
