App insstalls with its Bluetooth turned off!

This app installs with bluetooth turned off, so it looks like the battery module is dead. Go to settings on your phone, select Apps, then Ancel Battery Monitor. Turn Bluetooth on.
I didn't install it yet. I just tested it in my office by connecting it to an adjustable power supply and it works fine, soI expect it will work fine in the car.

Car battery monitoring

Use this on my wife’s 2021 Jeep Rubicon because it is not drivin’ on a constantly daily during the winter. Works awesome only issue is small but disconnects all the time. So have to link , but does what it says it will do. Helps a lot

Excellent but…

I have been using this battery monitor and app to monitor my RV battery for about a year now. The monitor works great. The app installed easily and connected to the monitor device easily and the entire system works well. So well that I’d like to monitor my utility tractor’s battery too but I see no way of setting up a second monitor (or third, forth, etc.) without corrupting the RV battery data.

Please update!

It would be amazing if we could calibrate voltage for devices out of normal range. Mine is .4 of a volt off . Simple update with the option for calibration would make the purchase that much better! Please consider!

Works Ok

I have the BM300 battery monitor. I mostly use it to monitor battery voltage. APP is very easy to use with all the functions.
Sometimes syncing data takes a bit long, but the biggest complaint I would have lately is at least once a day it will not let me use it until I upgrade the firmware. I upgrade to V8, successfully it says. Then the next day I need to upgrade to V8 again? Done this 6-8 times now! Every time it says “Success”!!!!
