MORNING GROUP DC Multifunction Battery Monitor Meter,0-200V,0-10A (Widely Applied to 12V/24V/48V RV/Car Battery) LCD Display Digital Current Voltage Solar Power Meter Multimeter Ammeter Voltmeter

Great monitor that can be customized with whatever battery you're using so the state of charge shows correctly. I was doubtful that the 300A shunt would be accurate at reading very low draws but I was amazed to find it was accurate down to the mA level on a small load. It was within 0.02mA of my actual multi-meter at measuring a 750mA load. Outstanding! Make sure you read the instructions and set the correct shunt value on the controller or your readings will be off.

Seams like a good product. Have installed and working well. Display is bright.

cannot write tech review it's not setup yet

screen is not so much dim but needs to be viewed straight on, but its very accurate and minimal standby power draw

This meter gives me an accurate real-time measurement of my RV house battery. I basically like the meter. It is easy to read and attractive.As others have mentioned, the spring-loaded wire connectors are unreliable and unsafe. I replaced the connectors with screw-type 3.5mm PCB connectors also from Amazon.As other reviewers have said the Amp-hour reading usefulness is doubtful. The meter doesn’t or can’t differentiate between discharging and charging. So the Amp-hour read just accumulates all current flow. One would need to reset the reading every time the charging cycle stops to get an accurate measurement of the battery‘s performance.I give it 5 stars because it works for my application and the hassle of replacing the connectors was not difficult for me. YMMV
