I can see how that might put unnecessary wear and tear on the BMS. If it were to fail to open the HVD, then I can see how the older weaker battery could get over charged.
I agree with your premise that it is not a good idea to put batteries of different vintages in parallel. I am just wondering if these batteries might be a little more tolerant than Lead acid?
