Smart BMS with no BS

The support response is amazing. You don’t always get the feature you want but they explain why. The app itself rocks! I use it for my DIY li-ion battery packs. It tells you the current load real time in use. The gui won’t win any awards but it get er done. 5 stars here...based on sipply and demand. I demanded and he supplied a great product.

Instructions for this powerful app?

I have 5 new LFP batteries, all with this BMS and bluetooth. It was not difficult to set up, but I needed help finding how to set the battery capacities. Simple to find the battery voltage, amps in or out, estimated SOC, temps, and some max and min numbers, and the cell voltages in comparison.
It seems amazingly powerful, with plenty of settings to tweak in the config mode. Do I trust all the default settings? I can find them.

But I can’t find a manual. There must be one, and it hopefully gives suggestions on how to utilize the power of the app.

Great configuration options

This is a great app. I wish I knew how full featured it was before I purchased my bms because I bought the PC adapter at the same time to get to all the configurations. This app has everything I need. Awesome app!
