Description of ⚡️ Optimal Battery Protection: 12V Low Voltage Cut-Off Switch for Under-Voltage Control, Safeguarding Against Over-Discharging

This is a under-voltage switch controller used to turn off the power of load in the event of the voltage dropping below a set value. This controller will help you to protect battery from over-discharging and prolong battery life. When the battery voltage increases to a set value, the module will automatically turn on load again. Designed with a LED indicator to show if battery is under-voltage. Both turn-off and turn-on voltage value can be adjusted by simply pressing buttons.

Do not buy. I had to buy another device.

Acquired to control a 4-pin automatic relay. Everything was working fine until I connected the relay and tried to control it. The screen became unreadable, made all sorts of noises. This device works perfectly, buy it instead. https://www.amazon.com/dp/B08GQSDQCC?psc=1&ref=ppx_yo2_dt_b_product_details

Pros
  • Terrace, lawn and garden
Cons
  • There are nuances

Wrong choice of solar and wind power

I bought two of these to be on the safe side. The first broke down when connecting. The screws broke under the screwdriver. Installed the second with no problems. Unfortunately it only worked for half an hour. The LEDs were still on, but went out in the range between 12V and 13V. bad buy.

Pros
  • Solar and wind power
Cons
  • No power

Good device but not for 20 amp load

easy to program following additional instructions works well as described. I would give it 5 stars but the terminals are too small to accommodate wire large enough to handle 20 amps and even with 20 amps the load on the relay gets very hot so I would put its load on a lot limit lower rating, say 5 amps or less.

Pros
  • energy regulator
Cons
  • safety
