    The Renogy BT-2 is a great little tool to monitor my two Renogy batteries. Easy to install. Nice & easy app to interact with.

    Bluetooth monitor

    Posted by Gord Joyce on May 24th 2022

    It comes with about 18' of wire which does not make sense to me for a wireless system monitor. So, I cut mine down to about 9" to keep a clean installation. I wonder if the 80' of usage distance includes the 18' of wire? Anyways the app works flawlessly and give the vital info needed. love it.

    BT-2 review

    Posted by david r watson on May 3rd 2022

    Think it's working properly. How does one really know. The instructions were poor as they did not explain how to connect two batteries to the BT. The software connection is poor. Need to pair each time you open app. App also crashes frequently.
