I've found some STI3470 (SY8120) microchip. As I understand it is some kind of similar chip.

Have the same issue with JK-B1A8S20P. It works normal on boot and discharging, but during charging repeatedly shows Protection (CPU AUX Anomaly). All temp sensors shows zero, charging amps drops to zero too. After some time - second or so - error message disappears, all temp sensors show some...

The continuation of the story with "CPU AUX Anomaly" without happy ending. I replaced all three chips with new STI3470. BMS "works" - it shows correct data, I can change settings, etc. But while charging it continues repeatedly reboots (maybe not so frequently as before), but with another error...

Thank you! It will take some time to do it. I'll post the results here as soon as possible.

Hello! I have a small home storage and try to choose a new BMS for it. My previous BMS was JK, and it does not work good. So now I want to try another vendor - JBD. My setup is 24v pack of 8 EVE 280Ah LiFePo4 batteries. Hybrid inverter is 3200W rated and has max 60A charge current and near 130A...
