Saw the other reviews and had to post that this works as advertised. Just installed it on battery. Buying another one for DC to DC charger. I had no problem finding and downloading the app to Apple phone. Had no problem reading my lithium battery bank via the app. It was all super easy to install, so it is bewildering the other reviews posted to the contrary.
Plugged it into my DCDC/MPPT charger/controller, connected via BT, and, bingo, everything was there. So easy to use and all the data is right there on my phone.
Needs improvement, doesn't stay connected with app. The App also doesn't remember the device. Have to hit add device every time i open the app. Then it says it already exists. User error? Not sure. Do like that is does give me the information on what's being produced.
Extreme range and connection improvement over BT-1

Using the BT-2 with the Rover Elite 20A. I previously had the BT-1 with the Renogy Wanderer Li 30A. You had to be close to the BT-1 to maintain a communication stream. But with the BT-2, I was able to be on the other side of my house and on a different floor and still was able to link the Renogy app with the BT-2. Very satisfying not having to walk back to make a connection like the BT-1.
