Review on 🔒 Enhanced Safety with Onyehn Protection Protector Disconnect Discharge by James Pfettscher

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 the charging voltage is 11V, the different voltage is 0.5V. Yes, I know, a bit wired, once you understand it, it will be easy to work with it. One of my devices is 0.1v no problem, if you want real 12v you set it to 11.6v. These are very cheap devices that do exactly what I need, even the more expensive protection module voltages can't do that, what these little guys can do.
