This 2021 M340i will be stored 4 months out of the year. I cannot seem to get an accurate answer from anyone at BMW as to which battery tender/charger will work properly with BMW's new 48 volt system. I have spoken with 4 different sources and they all simply direct me to BMW accessories and the two chargers they offer do not specify 48 volts. Thanks in advance for any information!
