The only thing that comes to mind are rectifiers used in the telecom industry used for floating charges across the batteries for -48 VDC systems, as well as energizing those systems when operating normally. And some of those have some pretty hefty wet cell batteries. Could work if setup correctly, but often are 220 VAC input.

Sorry. Mark.
