70 Amp 2 Alternator Isolator

70 Amp 2 Alternator Isolator Charge multiple batteries or banks of batteries automatically from one or two alternators without overcharging. Battery isolators isolate charge current and stop it from recirculating, thus preventing one battery from discharging into a lesser-charged battery. When properly installed within the boat's DC system, the alternator remains connected to the batteries at all times, eliminating the possibility of damage to the diodes. Charles Battery Isolators are built to be robust, either leg of the isolator handling the entire alternator output amperage rather than a portion of the rated load. Please note that by inserting a battery isolator into the system, a voltage drop of 0.7 to 1.5 DC, depending on the charge current, will occur. 70-250amp, 1-2 alternator, 1-3 bank models available. Mfr?s one year limited warranty, made in the USA. 93BI702/3-ASh. Wt. 6 lbs.70amp2 alternator, 3 bank battery system
