BI-1602 Battery Isolator for 10-350A Alternators on 12, 24 or 32V Negative Ground Systems

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.

Great oil for BMWs
Size: 1 Quart Pack of 6
Not much too say, it's the classic oil, only thing I can note is that it came with the old packaging and all that, but it works great for my car and runs smooth and without noises or temps, good value, and fairly fast shipping, good thing I can find it on here because none of my local auto stores had it on stock.

It works.
Size: 5 Quarts, Pack of 3
Ran this for 5k and did oil analysis. It performed identically to Mobil 1 ESP 5w30. No issues, stayed in grade, nothing negative. That said, it was no better than ESP and wear metals were functionally the same as multiple other similar rated oils. It’s perfectly fine, but not better. It’s a great value. I wouldn’t use it for extended oil change intervals. No oil consumption noted.
