Works well providimg a dummy load of 150 watts to test battery capacity. Menus are on screen. User interface mot the best, but not hard to figure out

Very capable and flexible device, but instructions are next to none...

I have MakeHawks other load tester and it has been working good, however it doesn't have low voltage cutoff like this one does. This tester allows you to set the low voltage cutoff so it can be used with lead acid and other batteries that do not have a built in BMS. This tester also has separate leads for the amp draw and the voltage reading. This should make this unit more accurate, in fact the voltage reading at the tester was very close to the reading I took at the battery with my Fluke meter even under load. I have seen some reviews saying this unit wasn't accurate so I will be doing some more testing and will update if I find this to be true. The cooler on this unit is also nicer being that it has plastic around the edge, as the cooling fins on the older unit is very easy to bend. The plastic, which also looks neat with the LED's helps protect the cooling fins.

I've only used it a few days, but it works great compared to the 4 resistor purple board version.That one lost the capacity when turned off and back on. This one remembers settings, capacities, also has several modes to discharge batteries. The early version had 2 dials and you had to adjust it often to pull 150 ish watts. This one has a constant power setting. Set it at 145 or so and it will pull that no matter what the voltage as the batteries drop.Wiring on the purple board units is a little strange. Look at the diagrams. All 4 terminals have to be attached. I do like the full color hi-res display.The 4 resistor purple board "said" color display. But it is definitely monochrome. It was returned if you can't tell.The full color unit actually had some instructions, which were a little criptic... But it was relatively easy to figure out. I do like the on off switch they added as well...
