Review on 🔋 bayite DC 6.5-100V 0-20A LCD Display Digital Ammeter Voltmeter Multimeter: Power-Efficient Battery Monitoring Solution by Leroy Jacobs

Handy panel meter! I bought this for the "Power Usage" feature so I can track battery power consumption in my project. This seems very accurate; My charger seems to put the same amount of mAh into the battery after I've used it, as indicated by the used counter. I didn't know it also had low and high voltage alarms; You can adjust the minimum and maximum voltage settings. When the voltage exceeds or falls below the set value, the meter backlight will flash. This is very useful in itself as you can instantly check if your battery is dead without actually having to read the voltage on the screen.
