I have this battery () on my Ryobi lawn mower

They offer this BAT-BMS App (https://play.google.com/store/search?q=bat-bms&c=apps)

Everything works as it should, but there is one feature missing from their app and it is to warn or let me know when the battery was very low.

Was mowing the yard the other day and got carried away and for got to check my phone and ran the battery dead. Thank goodness (2 - 50 foot extension cords and the charger) I was able to input enough charge to get it back into the shortage shed to full charge.

ANYONE have an app that could monitor the battery and send me a audio tone (always wearing head phones listing to music)?

Could write it myself if I had any idea where to begin.

nRF didn't see it. It sees other devices (wife's car, my blood pressure device) but not the battery

Before reading the battery data, the app needs to connect directly to the Ryobi lawn mower itself.
Could you share a link to the exact model (Ryobi lawn mower) you're using? (The first post doesn’t show it.)

Also, just to confirm, the nRF app isn’t detecting the mower at all, right?
Is it possible the mower is already connected to another app?

There is not connection to the Ryobi mower. I replaced the Ryobi lead acid batteries with a Lithium that has the build in BMS

Every time I try to post a link to the battery on Amazon it converts it to something media and doesn't work

If you use cut and paste this description you will find it

agree!
if the nRF app can detect the BLE Battery Module, then we can use any B4X example to read the battery data.
To move forward, we’ll need answers to the questions in #6 and #4
