Pros & Cons
Pros
The car has a built-in app to monitor its battery life. The app is free and easy to install using the car's qr code. It uploads a 24-hour datum to the phone when the car is connected. There are multiple apps that work with this device.
E-450 battery/alternator to provide charge whenever its voltage is at least. High accuracy on voltage readings. Allows for hands off static voltage and cranking voltage evaluation.
Cons
Battery charge level scale is inaccurate and not even close to industry standards. It tends to underestimate the charge on the battery, complaining that it is almost out of charge when it still has plenty of cranking power. Works only within 10' of th... Read More
Disconnecting and re-connecting the device sometimes resets it so it starts to work again. Won't connect even after uninstall and reinstall on my phone and tablet (and loosing all my data) it sometimes says the battery is still being charged after i'v... Read More
The only way to stop the app and regain use of your phone is to reboot it. The app builders know how the app functions and the company selling the sensor also knows many of them are going to be returned.
Highlights
Quality
It’s especially great to keep from depleting the battery to unhealthy levels
Very easy install and it hooked right up to the app no problem
This beats opening the hood every few days to check the voltage or avoiding an unwelcome surprise due to parasitic draw
This device works great for monitoring the battery but many of its features are worthless for electric cars the cranking test c... Read More
Price
For the price this is an amazing tool
I was looking at very expensive sophisticated systems when i stumbled across this little lowcost device which turned out to work great
This cheap device will pay for itself many times over
2 this thing is what i needed so that i dont have to be in two places at once to troubleshoot this i dont have two of them wond... Read More
Competitiveness
Better than a auto parts store test because it tracks the voltage during an actual start
I won’t know for sure if it stays within that range but i plan on comparing it to other devices mostly multimeters and seeing j... Read More

Otherwise it does what is says and now i can easily tell if my van has juice to start
Posted by a reviewer on Amazon
My van lowers the static voltage significantly when unlocked making it difficult to get an accurate manual reading even with a cabin voltmeter
Posted by a reviewer on Amazon
If the static voltage seems low with this device running the remote start in cranking mode gives another piece of data with which to evaluate battery health

I have a victron energy controller and a connected the bluetooth to it once and it never connected again this thing is 10 times cheaper and reconnects every single time shows me a cool graph not sure if its really recording history but it shows me my current voltage when i check on it one of my inverters is going bad and every time i pull a load through it says that im at like 10

Got this because my siennas battery would just go dead for no reason
Posted by a reviewer on Amazon
Dead battery is no fun when you need to be somewhere
Posted by a reviewer on Amazon
I did not mount the negative cable to the negative battery post just used a nearby ground screw that i found near the battery
