About this app

Battery Monitor BLE is an application for car battery monitoring, which can monitor the real-time voltage of the car battery; count the historical voltage of the battery; it can automatically test the battery startup voltage, and support idle and high-speed charging tests. All data is synced to the mobile app via Bluetooth.

Ratings and reviews

I tell you what for $20 you sure get alot of very useful features/information about your batteries, i own 2 of these 1 for each vehicle & i know my voltage is a bit low to hit the remote start & let it charge up also i compete in car audio so it helps to know the current voltage accurately & these are very close... Wish I was able to display both batts at once not have to go back & forth between them if I could suggest any additional features that'd be the only thing I'd improve... A+++

This needs a function to export data, which is very helpful when getting warranty replacement on a weak battery. Also, if you have multiple sensors, the app keeps changing to the sensor with the strongest bluetooth signal. It needs to stay on the chosen device until the user changes it. It would also be handy to have a quick device selection on the main screen, rather than having to go into settings to switch devices every time.

You're missing out if you don't have this device and app for car audio enthusiasts! It would be nice to be able to switch batteries in the app instead of doing into settings to switch. I run 2 AGM batteries and I would like to be able to see both. I do have a device on each battery. They are labeled front and back, but I can't switch easily. They should both be displayed if you have more than 1 device. Awesome work!

What's new
