Description of ๐Ÿ”’ Enhanced Safety with Onyehn Protection Protector Disconnect Discharge

Board Size: 57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H), Input Voltage Range: DC12-36V, Control Accuracy: 0.1V, Power Consumption: <1.5W, Maximum Amperage before Breaker Trips: 20A.Package Included:2x Protection Module. Programmable battery low voltage disconnect switch for DC12-36V lead acid battery and lithium ion battery. It's a protection switch module, not included batteries itself.Compatible Battery: lead acid, lithium ion battery, solar panel battery. On-board momentary push button to set the low voltage disconnect parameter and 3 digit red LED display the parameter easy to operation.When the battery voltage reach the setting values, the module will disconnect load automatically to aviod the battery from over discharging to prolong the battery lifetime. Reference formula: charging voltage = rated voltage x 1.2; charging current = rated current x 0.2. Reset:When the power is off, press and hold the two buttons at the same time, and then power on. At this time, the screen displays "888", indicating that the factory settings are restored.The factory-set protection value: 12V, difference value: 2V. Difference Value"is the value between the battery voltage to disconnect and the battery voltage to reconnect. Display is accurate, the switch module is quickly to open and close when near minimum voltage; Settings is stored non-volatile, it can keep set when power off.

Ideal for protecting lead-acid batteries in children's ride-on toys.

It seems that Peg Perego doesn't use any kind of battery protection in their kid's ride-on toys. My guess is to sell more of my very expensive batteries. The lack of protection circuitry will result in frustrated kids draining the battery to a dead end and constantly stepping on the accelerator to kill them some more. Once lead-acid batteries drop below 11 volts, they become irreversibly damaged, and the damage only lasts once. When the circuit is installed, the toy will automaticallyโ€ฆ

Pros
  • Reset: With the device off, press and hold the two buttons at the same time, then turn on the device. At this point, "888" will appear on the screen, indicating that the factory settings have been restored. Factory set protection value: 12 V, difference value: 2 V. "Differential value" is the value between the battery voltage for disconnecting and the battery voltage for reconnecting.
Cons
  • There are other interesting options.

Works great with IOT relays

This is a very basic but ideal battery pack. I set one up with a charger connected to the IOT relay to turn on the charger when the battery is 25% empty and then turn off the charger when the battery is fully charged. Another voltage protection module that I will use to shut down the battery when the voltage gets too low. A little fun problem I set (left knob 11.5v) then set a different voltage (right knob to 0.5) it's connected. until you understand, if the total voltage is 12V and theโ€ฆ

Pros
  • Low Voltage Programmable Switch for 12-36V DC Lead Acid and Lithium Ion Batteries This is a safety switch module, batteries are not included. Compatible Battery: Lead Acid, Lithium Ion, Solar Panel Battery
Cons
  • Available in white only

Insufficiently accurate use on a 12V lead-acid battery.

Voltage readings vary 0.5V peak to peak at steady state. No downloading. I'm measuring the battery right now. I would think I have a bad module, but both do. the same amount. 0.5V point. Of course, the absolute voltage measurement between them differs by about 0.4 volts. connected to the same battery. To expect any benefit at all, the circuit has to filter this display instead of using it directly. it's not like this. the brain seems to use each measurement to decide whether to turn off theโ€ฆ

Pros
  • display is accurate, switch module opens and closes quickly when voltage is close to minimum; Settings are stored in non-volatile memory and may be retained when power is removed
Cons
  • Wrinkled
