Good afternoon! A little over a month ago I bought the AC300+B300K set, but I’m having a problem with updating the BMS firmware on the B300K. The app constantly shows that a new update is available (currently version 1067.16), but when I press update, it says it’s already updated. This has been happening for several weeks now. I also heard that with the update it’s possible to activate the low current adaptation mode so the station can charge, but this function is not available to me at the moment. I tried disconnecting all connected devices and reinstalling the app, but nothing has helped so far. For now, I connected a voltage relay to the charging socket so it won’t supply current if the voltage is below 200V, but this function would be very useful for me when electricity is available only 2–4 hours a day, and I’m concerned that the firmware is not up to date.
