utipower Multifunctional 12V LCD Battery Capacity Monitor Gauge Meter for Vehicle Battery, White

I have not had ample time/opportunity to test the accuracy but looks good so far i'm happy!

Small but easy to see and read. I cut holes in 1/4" thick plywood and pressed them into the opening that I just cut. I then soldered and heat shrunk longer lengths of 16 gauge wire before soldering the other ends to alligator clips so I can attach to their respective battery posts. I have the positive lead on the 1st battery and the negative lead on the last battery. One battery bank has fourteen 12 volt deep cycle batteries and the other has eight 12 volt deep cycle batteries. All are wired in parallel. This gives me an instant readout of the battery capacity and by pressing the button, it shows the battery voltage. Not sure on the accuracy but they are relatively close to what my 12 volt chargers say. Another click and you shut if off. The green screen with the black is easy on my eyes, too.

I see some complaining that its not accurate but its accurate when compared with my multi-meter. The only things I don't like about it is the only mounting option would be to just drill holes in it and screw it into the wall. And I don't like that there is no cover on the back...I'm guessing it is meant to be mounted to a wall but that isn't a good option for me.

I had my doubts with this as I have another battery meter and it would show a higher percent that this one. Well... after testing both I found out that this meter is actually the correct one.Remember folks, different meters calculate "Full" depending on different voltage. I use this to monitor my RV batteries and it does a great job because it doesn't factor in the operating voltage (output from an alternator).I also love the fact that I don't have to reach the back to turn on or off as other models do. It has an on/off button on the front.

Easy to install. It's part of my bike safety checks. Nice readout. Saves me a load of time knowing at a glance the status of my battery. Too bad it doesn't measure battery health.

It works good but I thought I would get 2 of them that’s why I bought this one. There was same one that showed 1 picture and was 10 bucks but I chose this one because picture showed 2 of them for 15 , a little deceiving and description didn’t clarify how many they will send so I paid 5 bucks extra for this :/

Before receiving this product I was not sure where I should install this meter. I found the perfect location is on the battery box (side way) to easily access and prevent it from traveling wind and dust. After peeling the plastic film off the device (not shown in the attached pictures), it really looks nice and professional. I now can check my voltage and % of charge any time I want to use (pull) my RV.

Extremely irritating that the unit does not include the connector and wires so you can connect it to something. Had tp pull the connector off and solder wires directly to the board.I am using this unit for a homemade and 3d printed work light that I use every day at work. I didn't expect very accurate readings as it goes off of battery voltage to determine a percentage. Seems to be accurate enough for the purpose. Backlight is a bit dimmer than I would have hoped for, but it will do. Hopefully is lasts, seems a bit cheap.
