[Lowfer] MFJ-4035MV power supply as "float battery charger"

[Les Rayburn]

Currently I use a series of 12V deep cycle marine batteries to provide 
emergency power
to my Icom 746 or whenever I need to reduce all noise to the minimum for
weak signal work. I'd like to modify the system to always supply power using my
MFJ-4035MV power supply as the "float charger" to keep the batteries
charged, and when ac fails, I'd have instant change over to DC.

I know that it's necessary to protect the power supply from reverse voltage by
inserting diodes, and have found plans to modify Astron supplies for this
type of work, but nothing specific on the MFJ supply. Just wondering if anyone
knows what kind of protection will be needed?
