Review on ⚡️ NOYITO 12V 24V Battery Charging Control Board: Efficient 12-24V MAX30V Switch for Safe, Energy-saving Auto Power Off by Bruce Marable

July 31, 2021: First connection and test - Very pleased that I can use this with a buzzer as a regulated 12V DC voltage. The inverter voltage drops from 13.5 VDC to 13.1 VDC. I connected a switch to mute the buzzer until the battery float voltage recovers to 13.4VDC on a brief power outage or on a longer outage to reset the voltage range from 11V to 12VDC and me about it need to connect my backup battery inverter or generator system to operate my security system and fridge freezers. Very bright voltage LEDs. Time will tell as to durability - reliability is the sole reason for the 4 star rating.
