Question about the order of battery charging/discharging as per their LEDs?
Hello All, I have a question regarding how batteries are charged and discharged when looking at the LEDs in the front. For example, let's consider two wall-mounted Sunsynk 5.12kWA BYD batteries. They have 6 LEDs in the front that indicate the SOC of the battery. They are connected in parallel in a Master / Slave configuration with the Master's P+ terminal connected to the inverter and the Slave's P- terminal connected to the inverter. When looking at the LEDs would you expect the two batteries to charge and discharge together indicating the same SOC percentages or would you expect the Master to charge/discharge first and when it is full/empty then the Slave to start charging/discharging?
Or perhaps any other behaviour indicated by the batteries LEDs?
I've got pylontech batteries, so different LEDs, but i have my own software talking to both batteries pulling out all possible data from them.

You can see charge/discharge currents/power/voltages/everything else there (and my setup is actually not ideal, because i have both inverter leads connected to master battery (first battery) which should in theory make it charge and discharge slightly faster, but different between batteries is actually causingmore difference and 2nd battery (slave, further away from the inverter) is the one that charges/discharges faster)
