hi guys, today i wanted to upgrade from 16s to 20s, i managed to make it work the bms was showing 20s with all the setting, then i disconnected it to finish the welding on positive, and when i turn it back on, it show me 2 alarme and everything is gone 😨. I tried to disconnect and reconnect the equalizer cable feom the bms and still the same.

I hope someone know, thanks to you all guys !

1- cells not equals to setting
2- Protection CPUAUX anomaly (i'm scared of that one)

Now https://ibb.co/wYx0RR7

I'm even willing to pay anyone that can help me to solve this matter 🙂
 
You have to set the right cell-count.
If not you get errors.
But mine was showing all the single cell values with the wrong cell count.
 
hi dominik,
the setting is correc, its already on 20s count and the other setting too are correctly showing, the problem doesnt come from that :(
 
The same here, I bougth a BMS at HankzorBMS Store in Nov 2022 (and two in summer) and 6 weeks later the App shows two Errors: 


1) Protection (Cpuaux Anomaly)
2) The Temperature Sensor is Abnormal



All trys to reboot, make power less (10min/2days), use other versions of the App, gewire the batteries, check voltages, ... doesn't help.


In parallel I contact the seller - the communication was worse. Morste time not one word, only links, pictures to QR codes, numbers and textblocks. Not only one time I get a feedback about the errors. (Not sure what i should do the the IOS APP or the protocoll description) - see below


I also ask for 'repair, replacement, 1 year warrantie, 90 days money back - nothing.


!!! DON'T BUY FROM HankzorBMS Store !!!
