The application is used to match a HA11 or HA12 battery equalizer. After the application is opened, it autmatically display the surrounding equalizer through Bluetooth scanning. After connecting with the equalizer, it reads the voltage and historical data of each battery of the equalizer. The read data is displayed in graphic form, which is convenient to check the battery status.

Ratings and reviews

The app worked fine for a over a year. Now there is a white screen thats blank like others are experiencing here. I tried deleting the app and reinstalling but that didn't work. I even tried installing the app on another phone because my phone is older and even that didn't work. I'm gonna try to disconnect the box from the battery for a few hours then reconnect it and see if that works but I'm don't think it will because others have tried it here already.

Installed it worked at night for a few hours, but in the morning, it didn't connect anymore, I cleared cache, date, installed app on 2 cell phones, it didn't connect more bluetooth. I don't know if Black Box is working because it lost bluetooth connection even trying to connect 5cm away.

Heyy... I would say very good... but having a 4x12V battery pack when i try to wahtch the realtime graph resized to see how balancing works, it is impossible, as after the resize at the next refresh, the graph is normalized to have 0 in middle. Anyway, would be nice to have some drscription of the protocoll used, so i could build an addon for Home Assistant..
