Daier XH-M609 Battery Low Voltage Disconnect Protection Module with DC Output - 12V-36V DC Review

This is great for turning off the voltage while the battery is in use. It stops outputting but you can't leave the battery connected. This power outage (this product) persists and continues to drain the battery. I just have to remember to take out the batteries when not in use. It would be better if it went out completely and you had to turn off the power to get it back. I use this to prevent my batteries from draining when riding with kids.

I don't know why Revane wanted me to appreciate the warmth, transparency and thickness of it. In any case, this low voltage protection circuit protects you from running out of batteries. But it opens the contacts of the load control relay only when the voltage threshold is reached, and the protection circuit itself continues to drain the battery. I didn't notice it in time and it cost me two fake M18 batteries. I assume this works as intended. I just wasn't smart enough to fully understand the…

I use it for a 6V forest camera from a 12V lawnmower battery. With transformer to step down the voltage from 12V to 6V between the camera and the shutdown protection module. He switches off. It drains the battery after turning off. Not much, but there is. A big problem is inaccuracy. It measures and displays a battery voltage that is 0.4V lower than the two voltmeters I used to check accuracy. Even my automatic loader is more accurate. So you need to monitor the battery for the recommended…
