Name: ARCO Battery Isolator BI-0703
Brand: Arco Marine Parts

ARCO BI-0703 solid-state marine battery isolator for 1 alternator, 3 batteries, 70 A max; rated for 10–350 A alternators on 12, 24 or 32 V negative ground systems.

Description

The ARCO Battery Isolator BI-0703 is a solid-state battery isolator for inboard and outboard boats, configured for 1 alternator, 3 batteries, 70 A max.

How it works

The isolator is a solid-state device that lets current flow in one direction only, so a single alternator can be connected directly to multiple batteries without the higher-charged battery discharging into the lower one. All batteries are charged automatically, in proportion to their needs, whenever the engine runs. When used with selector switches, the switch position does not need to be changed to charge both batteries.
