[A Must-Have Battery Monitor for RV Cars] RV battery monitors can detect RV’s house battery banks status in real-time, and then prevent the potentially damaging of accidentally overcharging or undercharging, a must-have for optimizing performance and maximizing the lifespan of batteries.
[Measurement Range] Koolertron smart shunt adopts a pure copper shunt, high-precision, and low-consumed, wide measuring range, Voltage range of 10V to 120Vresolution: 0.01V, and amperage up to 400Amps resolution: 0.01Amps.
[Support Mobile APP Control] Download the app and connect Bluetooth, and then you can set/change all settings of the battery shunt and view all relevant data in real-time on mobile phone. And also you can view/export of historical data to better optimize battery system.
[Equlied 2.4-inch LED Display Screen] The bluetooth battery monitor 12v will track information about amperage, voltage, current, consumed power & battery capacity, displaying on the LCD screen where can be seen at a glance, konw the stutas in realtime and take instantly actions when something goes wrong.
[Programmable & Optimizing] This smart shunt battery monitor supports secondary development with some built-in communication protocols, meanwhile, Bluetooth battery monitor will collect some data when the battery banks working, which helps a lot in optimizing battery use and performance.
[Great Protection] If configurated with a relay Not included, the 12 volt battery monitor can offer under-voltage protection, over-voltage protection, positive over-current protection, negative over-current protection, over-power protection, and over-temperature protection.
[Widely Applied] The shunt supports both self-powered wiring and external power supply wiringcoming with a 5m length cable, so it’s very handy if you need a battery monitoring system in your RV car in the summer, and then repurpose it for something like an ice fishing shanty in the winter.

It monitors my second battery perfectly

I use this to monitor the camping battery. For me, it's the perfect device because of the features, including Bluetooth, it offers although for some, it may be too much information crammed on the tiny screen. I enjoy having all the data up front and not having to scroll through a bunch of menus to see chatge/discharge rate, battery percentage, amperage draw, and usage over time.

Ignore the negative reviews... This monitor is GREAT

After using a cheaper round monitor for two years, this monitor is a Huge upgrade. The review saying that it doesn't adjust to the battery level is just ignorance. If you have a battery you should know how many Amp hours it is and you can program it to that. It has worked great for me for a year now and is very accurate with the battery level. Buy this monitor and you won't regret it.

Screen stays on all the time

Nice color screen, I can't get it to change front Celsius to Fahrenheit but maybe I haven't figured it out.

Nice fully featured battery monitor for the money

Display is sharp and easy to read.
As others have noted, the 15 ft display cable may be too short for some RV applications but it actually worked out perfectly for me. To connect to my Lithium battery and cables, I had to swap out the lugs on the shunt with smaller (5/16") nuts and bolts.
TIP: I couldn't find how to turn off the display in the documentation, but through trial and error, I figured out that pressing the up and down arrows simultaneously, toggles the display on and off (I wonder if this is what's happened to some of the people who report it stopped
