BI-1202 Battery Isolator - 120A - 1 Alternator, 2 Battery
The Arco Marine BI-1202 is an inboard/outboard battery isolator that can handle 1 alternator, 2 batteries, and 120A maxrated for use with 10 to 350-amp alternators on 12, 24, or 32-volt negative ground systems.
Features:
- 1 alternator, 2 batteries, 120A 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.

The ARCO Marine BI-1202 Battery Isolator is an essential component for any marine setup requiring efficient battery management. This solid-state device is designed to handle one alternator and two batteries, with a maximum rating of 120A, making it suitable for systems with 10 to 350-amp alternators on 12, 24, or 32-volt negative ground systems. With the BI-1202, you can rest assured that both batteries are charged proportionally to their needs while the engine is running, providing reliable power for all your boating adventures.
One of the standout features of the BI-1202 is its ability to allow electrical current to flow in only one direction. This means that you can connect your alternator directly to two batteries without worrying about the risk of a higher-charged battery discharging into a lower-charged one. Additionally, when used with selector switches, you won't need to change positions to ensure both batteries are being charged effectively. The ARCO Marine BI-1202 ensures that your batteries are always ready for action, so you can focus on enjoying your time on the water.
