Review: Prático - Muito útil Review: Excellent , simple , accurate unit - Worked perfectly right out of the box. Nice heavy duty acrylic base and super heavy hardware. Simple operation is refreshing in this overly gimmicky app-inundated world we live in. Some other manufacturers could take notes from this monitor! Others have said there is no way to secure it into your cutout if you can’t access the back. I can confirm that. However , a 2 1/8” hole saw produces a perfect fit in plywood. I didn’t need it but one could add a single layer of electrical tape around the perimeter for a super snug fit. Yes, cord is too short. Ended up being just enough for my application. You can extend it without too much trouble. It’s a standard 5 pin JST-XH. Battery sampling wire I used was 18awg. The screw terminals on top of the unit worked great. Philips, very small. Consider tinning the end of your wire and then smashing it flat and trimming it square for a good connection. 18 gauge is probably about as big as it will accept. Even the backlight is great. When the backlight is turned off the screen still glows ever so slightly so you can read it. Perfect for nighttime in the woods. The screen is quite shiny so consider glare from windows when installing. The accuracy of any monitor depends on your configuration! For my one year old AGMs I used 50% of the rated capacity and charged them up fully with a good 3 stage charger before connecting this monitor. Then set the current SOC to 100 and forgot about it. I set zero % SOC voltage to 10.1. Have a couple weeks camping in the RV so far with good results. ## Features - BATTERY MONITOR WITH SHUNT – Read State of Charge (%), voltage (V), charge/discharge current (A) & remaining capacity (up to 999Ah) in real time — like a fuel gauge for your battery bank.

Provides more useful information than a simple volt meter, allowing you to understand what's actually going on with your battery system.
