Review on 🔋 QWORK Battery Monitor Voltmeter Ammeter: Accurate Voltage & Current Range 8V-80V, 0-100A Meter for Auto Car Motor Boat Caravan RV by Chuck Derrick

I upgraded my 48v lead-acid system in my Taylor Dunn electric car to lithium. The battery gauge on board was no longer accurate as it was made for lead-acid batteries. But with this meter I can program exactly when it is at full voltage and fully discharged. You must do this once. And after that, the counter is very accurate. I also like that it shows the amp power while driving. With this system, I've found that my car actually charges when I'm idling. Because it not only shows you the consumption of the amplifier, but also shows you the charge of the amplifier. It is very convenient when charging. I can see if the charger is really putting out the right amount of amps. I recommend it. Very easy to install
