Ac200max firmware update 2

I am having the unreliable SOC issues, could you please send the latest firmware update.

Try updating your app if you are using iOS. I now have the option to ”upgrade” the BMS firmware on mine, sim emyesterdays app update. If you do update it please let me know if it works ok.

That’s helpful, I will check when I am back.

Did update from iPhone and all seems fine. It is on the new BMS version and after the update the battery status dropped from 100% to 89% which suggests an improvement as it is now charging to 100 % capacity. The only thing I was careful off was to have full signal from wi-fi router and also keep iPhone close as Bluetooth does not have a long or reliable range.
