2 PCS Low Voltage Cutoff, Icstation DC 12V-36V 20A Over Discharge Protection Low Voltage Protector Disconnect Switch Module for Lead Acid Lithium Battery Solar Panel Light

Exactly what i needed.Good quality.

They work and are pretty easy to figure out. However, the terminals don’t hold wires that well. They keep falling out no matter how I clamp them down. Have to bring screwdriver with me or we might get stranded while riding power wheels around the neighborhood.Using it to cut the power from power tool batteries to power wheels cars/truck so they don’t get overdrained and ruined.It gets pretty hot, but keeps working pretty constantly when used for half an hour to an hour. Might want to run it with a relay instead of running power right through it?

Product works well for the price with relatively accurate output and control. My issue is that the circuit boards are just packaged and shipped in plastic pouches with no dunnage whatsoever so surface mounted components are bent from typical shipping handling. Fortunately my products work but I would not be surprised to find shipments arrive broken.

Great

There are two types of these and both look similar: ones to prevent overcharge and ones to prevent over-discharge. This is the latter--it disconnects the load when the battery voltage gets to low. I have one connected to my car's starter battery so that I can leave radios etc on all the time and not worry about draining the battery so much it won't start the car. I have another one connected to the auxiliary battery in my car. That battery doesn't have to start the car but I stl don't want to discharge it too much which shortens the life of even a deep cycle battery. I like these becuase it's easy to change the settings (the voltage where it disconnects when it gets to low, and the difference between that voltage and where it will reconnect. I set the low voltage at 12 v for the auxilary battery and 12.5 volts for the starter battery. Both are set a 1 volt difference so they reconnect when the engine starts charging the batteries again.) I really like that I can view the battery voltage all the time.

Works great. You hold the left button to set the voltage that the relay will switch off at. Then you hold the right button to indicate the voltage that the relay will switch back on. I had it at 14.4 and 1.5 so the relay turns off at 14.4 and on again at 14.4+1.5.It has some other features to create a slight delay in the switching. Not sure if this is necessary but it works great.I have been running this at 5 amps and 20v continuously without any problems.

These cutoff switches work very well to protect your batteries from being overdrawn and damaged. They are more economical if bought in pairs which is good because you will need a spare if one fails. I had one to fail and amazon replaced it immediately, no problem.

Only the directions on the actual Amazon seller page are correct. The ones that come in the package go to a look-a-like but do not work. Worried about how long this will last but other than that works great so far.

Likes:larger displaysimple to set upworks as advertisedNothing to dislike really unless it breaks and so far it's all good

Worked as well as advertised.

Disconnect function works well but the timer function that is supposed to allow you to stop it from cycling is inoperable which is unfortunate I like that it allows you to calibrate the voltage

Lv works great the only reason I gave it a 2 star is because I paid for two low voltage cutoff but received only one. Don't know if this was an errors in preparing the order. Tried to reach the seller but no response.Has for the LV I recommend it.
