I picked this up as part of my plans to redesign my layout in my camper shell. I have a dual battery system with a read out in the cab, but as most of the time in camp is spent at the back of the truck I wanted a way to monitor the batteries. The Mictuning double voltmeter is perfect for what I need. As you can see in the pictures I plugged it into a power supply at work that we use for testing and the read out is bright and easy to read. The set up is also simple. There are 3 terminals on the back, 2 silver 1 gold. Unlike most applications, the Gold terminal is the ground, and that is shared between your two batteries or power sources. The 2 silver terminals are for the positive lead from each battery or power source. I tested plugging in both positive terminals together, and separately and compared them to my Fluke 400a meter and found the mictuning to be very accurate. This appears to be fully sealed except for a small opening on the back so it should do great in the bed of the truck where there is a possibility of being exposed to the elements.

The media could not be loaded.

Should have a separate ground for each meter. I can see how the device has no space for a 4th terminal. When connected to the same power the MAIN and AUX meters read different voltages. Difference is AUX is 0.2V lower than MAIN. Not too bad for monitoring just vehicle batteries. Also, MAIN must be connected to see reading on AUX. This indicates that main voltage is powering the display. I have three of these monitoring two devices on three circuits. These are Okay for now. If I find a dual meter with same form factor (round) with separate grounds, I will change these out in a minute.

Works perfect and looks nice on my boat display panel

Worked Very well for my needs. I have a 2 battery set up in my truck with a ‘Smart Charger’ and a DC to AC Converter on one which I use for electric power tools. This was exactly what I needed to monitor battery AND system charging/re-charging. Installation for me was probably more challenging due to fact I replaced 1 of 2 cigarette lighters my truck had with this gauge. Increased hole size about 1/8” in circumference. Wanted it to look Good in my Chevy High Country Truck. Worked out well.

Bought two for my boat (with an aggressive, salty environment). One to install and a second as a replacement, should the first fail. After three years, have still never needed the back up.

Works good for my dual battery setup to ensure both batteries are at charging voltage. Lasted about 2 years before the led displays started glitching, took it apart and there was lots of corrosion on contacts on led board which could have been the culprit but I already ordered another one (different brand name, but same exact clone, just labeled with different name).. Low quality but great for the price and I couldn't find anything else in this form factor.

I'm seeing two common themes in the negative reviews1) Main worked Aux didn'tThe main has to be hooked up for the Aux to work.Run the main battery wire to the main batteryRun the Aux wire to the Aux batteryRun the - to a common ground.It's easy to tell which terminal applies to the Main, it's the one on top, just lik the Main read out.Aux is middle Ground is marked -.The other is that the meter lights saty on all the timeRun your Main wire through an ignition on wire at the fuse box using an Add A Circuit. Or run an On/Off switch through the Main wire.I haven't decided yet which way I want to go

Used for a modified Power Wheels project. Had a 12v circuit and a 20v circuit to be monitored and works like a charm. Flush mounted easily with step drill bit through plastic.

Mich haben zunächst die schlechten Bewertungen fast abgeschreckt. Primär wird ja immer die Messabweichung von bis zu 0,3V angesprochen. Auch bei Amazon.com.Ich hatte aber an meinem Verwendungsort nur minimal Platz und habe im Netz keine Alternative gefunden. Also hab ich das hier bestellt.Es ist absolut wertig und ist optisch ansprechend. Einbau und Inbetriebnahme ohne Probleme. Nun zur Abweichung. Bei der Main-Anzeige habe ich keine Abweichung zu meinem Multimeter. Bei der Aux-Anzeige habe ich -0,1V. Das ist aber für mich absolut im Rahmen der Messtoleranz. Sprich, mein Exemplar ist top für meine Anwendung.Ich könnte meckern, dass mich die Prime-Lieferung 7€ mehr gekostet hat, als die Lieferung aus China. Aber gut, war meine Entscheidung, nicht zu warten.Hinweis: Aus der Spannung des Main-Eingangs zieht sich das Teil seine Betriebsspannung. Sprich, nur die Aux zu messen, ohne Main, ist nicht möglich. Main ohne Aux schon.

Estoy contento, se ve muy bien, y funciona correctamente.Espero que dure...PD: durante el dia se ve muy bien, por la noche ilumina demasiado, puede llegar a ser molesto. Mejor ponerlo en un lugar que no te de a la cara directamente. Estaria muy bien poder regular la intensidad de la luz.

J'ai acheté cet engin pour effectuer un couplage de batteries en semi-automatique: je décide de monter ou non un relais de puissance suivant la tension de la batterie principale à l'aide d'un bouton poussoir et d'un relais auxiliaire en auto-maintien sur le + après contact.Branchement facile sur 3 broches: 0V, 12V batterie principale et 12V batterie auxiliaire.Encombrement correct: dimension identique à une prise allume cigares.La mesure tension est fidèle pour les 2 entrées MAIN et AUX.Le gros défaut pour mon utilisation c'est qu'il est alimenté aussi bien par l'entrée MAIN que par l'entrée AUX, donc pour l'éteindre il faut couper les 2 sources. Je comptais l'éteindre en mettant le 12V après contact sur le MAIN, et bien c'est raté, je vais devoir ajouter un relais supplémentaire pour couper le 12V de la broche AUX. cela va donc surcharger le montage prévu à l'origine de mon projet.pour le relais de couplage j'ai opté pour celui-ci:]

日本語コメントが無くて不安でしたが購入して良かったです。私の使い方は24vバッテリーのディーゼルの釣り船への装着です。ソーラー充電を繋げたバッテリーは「セル用」と「その他アクセサリー用」の２つがあり今まではアナログ電圧計で計ってましたが小数点第一位目盛りまでは把握出来ません。そこでこの商品を見つけて専用スイッチも装着しました。デジタル表示は最高です。ソーラー充電でどれくらい増えていくかも日々のチェックが楽しみです。
