Besides cutting off loads, should a master battery switch also cut off power to say a BMV 712? I've seen claims that the Victron BMVs will loose their settings without parasitic power from the batteries.
While here, will various Victron charge controllers also loose their settings without parasitic power from the batteries?
I like the idea of everything being off-off for winter storage and maintenance, including storing LiFePO4s at 40%.
Thanks,
