Battery Optimisation
Your battery management system (BMS) expects the battery to be compensated immediately for any drainage. If it cannot be (such as when engine is not running) it will turn off whatever is using it. Yes your battery could be at fault but I personally think the messages are just too much unnecessary information, which leads to confusion more than solution.
