### ⭐⭐⭐⭐⭐ Worth the money

Great bms I've got several of these and they're easy to install and setup

### ⭐ Works fine at first
*by K***N on December 21, 2025*

At first, the bms seemed good and the features all worked, but over a couple months they stopped working. The app won’t connect anymore and the over discharge doesn’t protect. I was able to get my 12v battery down to 6v before the discharge device cut off.
