Victron Cerbo GX update and Pylontech batteries keep losing maximum SOC (1% daily approx) until each bank is individually charged with no charge going into the bank.
Each day total SoC drops by 1%, and the batteries are in fact fully charged. When you charge each battery individually they go to 99% without any charge going into the device. This used to work before one of the updates, so the probability it is the Pylontech's BMS fault seems very low.
Using the Keep Charged, or Optimised with ot without battery life does not matter.
Asked the question during a recent demo and was told to add @Daniël Boekel (Victron Energy Staff) to the original questions and yet there is no reply or movement almost a month later, so adding an additional question on this topic.
