Battery Monitor BM2

The 12.34 V is why “Low Power”? It is a 70% range. 11.9 V is the low power

Can’t open app

This device (physical battery monitor)must be used with the bm2 app, this app constantly records my phone location and continually transmits to its servers which breaches privacy laws, this device does not require internet access to work.

Monitor works great it asked me once what the battery type is and since never has I have changed the battery type and can’t for the life of me figure out how to change it to suit what I’m currently using needs to be an option in settings to change it

The advert says Lithium only yet the setting and tests are for an automotive starter battery. A selection tool would be great to choose different battery types .

It works well but I noticed a massive amount of data being transferred by this app turnos supposed to be stand alone. Why?

Does anyone know if the Matson battery monitor works on lithium?

I m monitoring 2nd battery for my fridge , it would be good if they make this app to ran on CarPlay it would be good. Some glitches frizzing , simply restart and work again ,

Horrible, I’m right now about 10kms from the the system and still shows the same voltage and tells me the battery is full. 2 days ago the battery was dead and it was showing full in the app. I unplugged from the charger today and it was still showing charging the whole day. Horrible horrible horrible

Has been working fine for months but history of voltage is longer showing current voltage use.
