JK-BMS V14, V15 and V19 in parallel and first full charge. Why no 100% reset of the BMS?

This is a bit of an experiment, I wanted to do since the new JK-BMS V19 came out: paralleling all three BMS and see how they work together. I check for all parameters and settings in Venus OS first to ensure they are all correct. Secondly, I fully charge the battery to check on the 100% reset of all BMS... and found a problem when there is no communication to the inverter. As expected, the voltages are slightly different and some of the BMS do not reset. With inverter communication, however, the voltage will be shared across the system and the BMS reset perfectly. This is not particular related to JK but is valid for any other BMS as well which does not communicate with the inverter. So, here again, it shows that a data transfer between the battery and the inverter has a lot of benefits...
