I am thinking of installing a MEGAPULSE battery pulser to take care of my 4 x 110Ah house battery bank:

The question I have is do I need one, two or four units of this battery pulser? I have been receiving conflicting answers from two different suppliers.

Has anyone personal experience with such a battery pulser?
