Got multiple batteries that refuse to get along? This ProMariner ProIsoCharge 120 plays referee so your starting battery doesn’t get bullied by the house bank.
This smart isolator automatically sends charging power where it’s needed, when it’s needed, and keeps your engine-start battery safe from late-night stereo regret. As all 3 items are stand alone, I am willing to seperate the package. The Blue Sea Systems 5026 ST Blade Fuse Block, 12 Circuits with Negative Bus and Cover is $35, the 50 amp breakers are $10 each, and the ProMariner is $100
