Review on MakerHawk USB Load Tester - Intelligent Discharge Resistor Module for Battery Capacity Testing, Adjustable Constant Current, 150W 200V 20A by Richard Simmons
Adjustment knobs do not work
I bought this and was unable to use it immediately due to BMS delivery. After setting everything up with the BMS I tried to check the capacity of my 24V 120Ah Lifepo4 battery. The display shows the current voltage but when I try to start the test I cannot increase the draw. Everything stays at 0. Since the return time has expired I'm stuck trying to figure out what's wrong. I would recommend gathering everything before purchasing this product if it doesn't work like mine.
