Description of ⚡ DC 12V-36V Voltage Protection Module Digital Low Voltage Protector Disconnect Switch Over Discharge Protection Module Output 6-60V, Low Power Disconnection (2-Pack)

Specific information: the supply voltage is DC 12V-36V, the output voltage is equal to the supply voltage, this voltage protection module could control the voltage within 0.1V. Main functions: this digital low voltage protector is functional and practical, contains various functions, over charge protection, over discharge protection function, short circuit protection function, over current protection function. Diverse usages: these disconnect over discharge protection modules are suitable for a variety of batteries and lithium batteries, a wide range of applications, when the battery is under voltage loss or low battery, it will be automatically disconnected. LED screen display: designed with led screen display in digital way, which can allow you easily read the output voltage and stetting parameters, the voltage can be set within 12-36V as you like. Discharge protection for batteries: when the voltage of battery has reached the setting voltages, this over discharge protection module will disconnect the load automatically to avoid the battery from over discharging to prolong the its service life.

No instructions, no circuit diagram.

I don't know what to do with this, no wires, no schematics, no programming guide. I suppose you can try to figure it out, but nothing saved by trial and error when they fry.

Pros
  • A sea of positive emotions
Cons
  • Quality

Worked as stated.

I used this to fit a USB charge connector to my e-bike. It works as expected when I lowered the output voltage to 5V. Digital will help if you don't have a voltmeter. I checked it with my voltmeter and it matched.

Pros
  • Absolutely amazing!
Cons
  • Not all will fit

Capacity 20A 14VDC - NOT suitable for 18V PowerWheels retrofit

Purchased for Milwaukee Power Wheels 18V battery upgrade. Works great until it burns out. I've burned three so far and they only seem to last about two weeks each. The black part above indicates that it is rated for 20A 14V DC. It's just not designed for 18V applications. Will replace it with something else.

Pros
  • Ideal for outdoor activities
Cons
  • Not sure

Good price and consistency

I have seen them switch about 50mV apart which is probably enough for almost any amateur application. I use them to balance two 12v batteries (for a large UPS). They are connected in series and one is slightly weaker than the other, causing an increase in voltage in one of them. One of these modules is connected to each battery and configured to close a relay if the voltage gets too high. The small resistance is the burden. The batteries are now almost perfectly balanced.

Pros
  • Dope 🔥
Cons
  • Expensive

Okay, but be sure to turn it off afterwards.

Ideal for disconnecting the battery. I used these for my fake Milwaukee 18v batteries to power my 3 kids bikes (upgraded from 12v for faster speed). I've set the cutoff to stop when it drops (from a fully charged 20V) to 16.5V. It does a great job of cutting off power when the cut off voltage is reached *** but *** I have to remember to disconnect the battery from this voltage disconnect device or this device will slowly discharge the lithium battery even after a few days of use 17V to 0V…

Pros
  • Decent performance
Cons
  • Miscellaneous Miscellaneous

Old lure and switch

I bought 2 of these 4 months ago and they were perfect. Exactly as pictured and works exactly as described. I just bought 4 more and now it's a completely different product that just doesn't work. The picture shows that this is a completely different board, some SMDs have been moved and some are even missing (look at your R2 and R3). None of the pass-through components are the same, and most of them now look like cheap white-label knockoffs. Given the price, all of this would be forgivable IF…

Pros
  • Pleasing
Cons
  • Old model
