ARCO Marine BI-1602 Battery Isolator - 160A - 1 Alternator, 2 Battery [BI-1602]

The Arco Marine BI-1602 is an inboard/outboard battery isolator that can handle 1 alternator, 2 batteries, and 160A max. Rated for use with 10 to 350-amp alternators on 12, 24, or 32-volt negative ground systems.

Features:

  • 1 alternator, 2 batteries, 160A max
  • Inboard and outboard battery isolators are solid-state devices that allow electrical current to flow in one direction ONLY, thus permitting the alternator to be connected directly to two batteries without fear of one higher-charged battery discharging into the lower-charged battery.
  • Both batteries are always being charged automatically, in proportion, to their needs whenever the engine is running.
  • When battery isolators are used in conjunction with selector switches, it is not necessary to change the switch position to provide for charging of both batteries.
  • Isolators provide proportioning of the output or charging current on the alternator to the batteries as required, regardless of switch position.

NOTE: Battery Isolators cannot be used on 12 volt charging systems with 24 volt trolling motors or newer outboard engines with rectifier-regulator charging systems.

This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
