Hi, I have problem. Few days ago I replace my old battery with new one (ofcourse I swapped BMS to new battery). It didn’t show me this message for like 1-2 days and now my phone freaks and display it all the time. Is there any chance fix it? I tried all. Reinstalling software on new and old battery etc. Sorry for my bad english I hope you understand.
@maryjusz, You say you replaced the BMS board from the old battery over to the new one; Did you spot weld the connections or just straight solder them? Did you also cover everything up with good tape or what did you use to encapsulate the BMS board to the battery? Sometimes, even a very good soldering job isn’t enough :/
