Don't buy any other monitor but this one!
I seldom write reviews on here but this product so impressed me that I need to say something.First off, it was by far the easiest app aided device ever to connect to, update, and use. Once I installed it and the app it literally did everything else on its own. It connected to the app on its own, it downloaded the latest version of the firmware unaided, and started working in almost seconds all on its own.In addition to providing basic trip logs, it has a means for battery testing, it has a low battery alarm and the device has a memory which downloads onto your phone the data accumulated while your phone was away from the vehicle.Here's how to install it: https://youtu.be/WsOHdKPKeU4

i bought it for my RV, after mounting it in the battery compartment the bluetooth signal will not reach my Samsung S6 from the drivers seat of a 32 foot BUS. I may drill a hole through and have the transmitter on the inside of the RV instead of inside the battery compartment. It will transmit through the battery compartment about 20 feet.

Compact size/ Quality vs. Cost
BM2 Bluetooth Car Battery Tester/Monitor (07/09/2018) : Works perfectly as I needed, Compact and good quality product. I use it on my solar bank. Having all data from previous days to minutes is awesome feature but somehow I feel it's overpriced.

It works fine, but the app could use more features.
I wanted an easy way to check the RV battery right at the source. The application works, but wish it had a way to customize it. Right now, for example, it is reading 12.33V, 51%, showing red and "Charge Soon". Since this is a deep cycle battery, running at 12.3V is fine. I would like to be able to change the voltages levels where it changes from green to red, and when it says to charge the battery. I also don't understand what the 51% is suppose to mean; there doesn't seem to be a relationship between the percent and the voltage level. None the less, the hardware seems fine.

Works well, not a great representation of battery charge
This works really well - the issue I have is its just giving me a surface charge (so it goes down even though the battery has plenty of charge in it). It can literally report 0 volts at the terminal and car starts with no problem.

App crashes every time, unable to use EDIT: App updated, works fine
This worked but the most recent app update causes it to crash every time I open the app, making this product unusable. I will revise rating if they update again and make this usable againEdit:They revised the app awhile back and I forgot to update my review. I think there have been a few updates since then. The app is stable and I have never had another issue.
