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.

total garbage

The most incapable app - just one simple thing is all we ask done correctly: Show CORRECT charge %

Can it do this? absolutely not. had 80 amp hours left, four hours later at 4 amps I have 0 amp hours, that is 80 amp hours gone in 4 hours. Every time I check my battery level it seems incorrect so I found that if I go to settings choose BMS > BMS Read > then change any setting and I mean any setting just a little, like turn off or on the Balancer or change the delta by 1 mv up or down does not matter this is all just to be able to "Write" the new settings > Return to main screen and *poof* the battery % and amp hours magically changes instantly. This is a constant failure to report actual capacity and lets face it this is one of the main reasons for the app and is why % of charge is shown first at the top all big like it is important, yet in reality this app is garbage and shows an Untrue % all the time.

Developer Response ,

This is not a bug of the app. The app displays SOC as reported by BMS. If you get unexpected values - talk to your BMS reseller, could be HW or Firmware problem.

Please fix the rating. The problem you are complaining is not related to the App.

Almost perfect

The battery capacity is displayed according to voltage. With LiFePo4 this doesn’t work as the voltage curve is mostly flat. You have a coloumb counter why not use the amps in and out to calculate a realistic capacity monitor?

Developer Response ,

Hi Ericbj1
The App is just an UI for the Hardware. You have to ask manufacturer of this BMS to implement better capacity measurement.
