DROK RV Battery Monitor 12v - LCD Display Golf Cart Battery Meter 10-100v, Car Voltage Meter Temperature Gauge for DIY Project

Works as described

Great little device, I use it to monitor a power wheels I converted to use Dewalt batteries

This one was a little challenging to hook up. Depending on if you are going to run it in "series" or in "parallel". If you run it one way, you only see one battery's voltage. It will still work as intended, but you will only see that battery draining, so you don't really know if it is just that battery draining voltage, or all of them together. Hook it up the other way, which requires more involved wiring (on my cart anyway), and you see all batteries lowering voltage at once. I prefer this. I was going to do a test and hook it up behind the ignition switch to see if that would be easier but have not yet. DROK support did answer questions, so that was good of them.

Exactly what I needed

The meter seems to work, I can't speak for the accuracy of the voltage as it fluctuates a lot. It was reading at 48% and after I drove it around for about 20 minutes it started 52%, but I like the fact that it displays the actual voltage instead of just a battery icon with bars.I couldn't mount it where my old on was mounted, this one is bigger so I need to cut a bigger hole.My biggest complaint is that the wires are super thin! I didn't know they made wires that think. Id say probably 26 or 28 gauge. I was afraid to touch them.The screen is also not very bright. It's hard to read in the sunlight.Pros:-Voltage display along with percentage-temperature display-on/off button-priceCons:- Wire size. Id like to have seen 18 or at least 22 gauge wire. This wire seems very thin- Display is hard to read in the sunlight

Product as described

Won't read the volts of my lifepO4 battery correctly no matter what. Reset it with a 20v source, reads that correctly. I set everything correctly, even tried the auto features. Nothing changes the incorrect reading. I've checked with a multimeter and other components read the battery correctly. This monitor has never read the battery correctly unless I push a button and then the volts jump to almost the correct reading, let go and they drop. Really disappointed. All the wires are connected into it properly, just useless purchase.

Came quickly and just what I ordered ! Very pleased
