MNJ Motor Digital Voltage Multimeter - DC 6.5-100V 0-100A Volt Watt Power Energy Meter Ammeter Voltmeter - LCD Digital Display with 100A 75mV Shunt

I installed this as soon as I received it and it worked flawlessly for a few months and then the display went out. I contacted the seller and requested a replacement display only with out the shunt. The seller was very responsive and sent a complete unit and I received it 2 days before scheduled delivery. The new one is working fine and I appreciate the prompt customer service. Would buy from this seller again.

Good value, works exactly as advertised. I wired up as per the diagram and it worked with no issue. I use it to monitor battery charge and discharge/ usage stats and it does the job perfectly. I'd say it was about 99% accurate ( fine for monitoring ), easy enough to use and read. Only downfall is the 100A shunt is bigger than the unit.

I used this to keep check on my batteries for my solar system. It has a bright backlit display. It shows you the watt hours used, the voltage of the battery bank, the volts and amps being used currently.

Works great. My only complaint would be the tiny recessed back light button. You can't turn it on or off with your finger. You need a paper clip or the edge of a screw driver or pen, etc.Otherwise, its all good!

Works good wish it could read reverse current flow.If you charge through the shunt the current goes to 0 not a -value like my charge controllers show.Alarm voltages are user adjustable the display flashes on alarm there is no audible alert.

I bought 4 of these one didn't work returned it and got another one.

I followed the instructions and wired it according to the schematic that was enclosed with the device. The meter came on but would not read or indicate the current across the resistor load element that came with the meter. It did not work!Unfortunately, I had just past the window for return when I first tried to use it.

I used this on my boat and truck. Both applications worked great and Light up screen is very useful. I would recommend this product to my friends .
