### 2/5 — Only see one battery at a time.

*2023-10-10*

Bluetooth works good. It’s a bummer the app only allows me to connect and monitor one battery at a time. If I want to check my second battery I have to disconnect and connect to the second battery Bluetooth. Would love to be able to see both batteries at the same time.
