Thanks for making this app available with all the features and more. Your work has been great for the DIY community!

### 5/5 — Very nice

*2024-08-27*

I originally used the XiaoXiangElectric app for batteries, but it ran into a bug where it would display a ridiculous wattage that I knew wasn’t true.  I tried this app and it displays the proper values.

### 5/5 — OMG YES

*2024-03-11*

Hi I have an Onyx Rcr and the app that came with it XiaoXiangElectric was trippin on me and wouldn’t allow me to go into the controls section of the app. So I downloaded this one after so many other copy cats and I finally can charge my battery now!

### 5/5 — Great App For Your BMS
