BATTERY ISOLATOR 2 ALT. x 3 BAT 140A. 12/24V MAX.300A

Automatic battery isolators, allow simultaneous charging of 2 or more batteries with one or two alternators (see technical data). The automatic battery isolating diodes 'Very Low Drop' electrically isolate each battery to prevent the battery with the highest charge from discharging into the one with the lower charge. When charging, the battery isolating diode allows preferential charging of the battery bank that is most needed.
