Price was the best, just have to watch mounting board is open on back can and will short out.

Doesn't come with instructions so took a bit of fiddling to figure out how to use this - double press + allows you to set the cutoff voltage (default 12.0V), long press + sets calibration of voltage reading (one was spot on, other was off by 0.2V but was able to be calibrated easily). Double press - allows you to set return voltage/hysteresis to re-enable relay (default 2.0V). Long press - does something but haven't figure that one out yet.FYI both about 11mA with relay off, one unit was 47mA and the other 70mA with the relay on.

Have used these for a few power wheels conversions to power drill batteries, keeps the kids from killing a $70 battery. Also used one for a battery powered fan.

Very useful device for small project, It would be nice to come with housing or protective case.

Observe cut off setpoint:Press + button once to see turn off setpoint voltage.If left alone for a 2 seconds resorts to displaying the battery voltage.Set cut off setpoint:Press + button once to see turn off setpoint voltage.Press + button twice (or a bunch of times) until decimal point will flashes.Press + or - to adjust.Leave alone for a few seconds to go back to displaying the battery voltageObserve Hysteresis (voltage increase needed to turn on above cutoff setpoint:Press - button once to see turn off hysteresis voltage.Leave alone for a few seconds to go back to displaying the battery voltageSet HysteresisPress - button once to see turn off hysteresis voltage.Press - button twice (or a bunch of times) until decimal point will flashes.Press + or - to adjust.Leave alone for a few seconds to go back to displaying the battery voltageCalibrate:Measure voltage with a meter.Press and hold + button until voltage flashes.Press + or -to adjust value to match meterLeave alone for a few seconds to go back to displaying the battery voltage. I noted sometimes it shows 0.1V off.

I've used these for years to modify power wheels to run off of DeWalt and Milwaukee batteries. The quality of these devices has plummeted and they fail frequently.
