Grin's Cycle Analyst Grinspector is a battery test station that monitors & controls CC load capacity discharge testing with custom firmware loaded onto a standard CAv2.3 or higher.

I displats available capacity in amp-hours and watt-hours, internal resistance, and a graph of the discharge curve profile
It seems the stock setup from Grin only supports discharging a
36V battery at about 5 amps
48V battery at about 7 amps
over 52V you're on your own
Use a separate dummy load device or DIY resistor bank, space heaters, lightbulbs, hairdryer guts, paralleled nichrome wires, hot water tank elements etc
But even then apparently 35A is the limit at least at 52V
And 72V is the hard limit?
Not sure if that is the case when going this way:
It is also possible to hook up an active electronic load to the discharge port of the Grinspector if you want to test the batteries at programmable constant currents.
