BI-0702 Battery Isolator - 70A - 1 Alternator, 2 Battery

The Arco Marine BI-0702 is an inboard/outboard battery isolator that can handle 1 alternator, 2 batteries, and 70A max. Rated for use with 10 to 350-amp alternators on 12, 24, or 32-volt negative ground systems.

Features:


  • 1 alternator, 2 batteries, 70A 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.

Engine Air Filter
Size: (Pack of 1)
This engine air filter fit perfectly in my 2018 Honda CR-V. No idea how it will perform but so far the Check Engine Light has not come on since installing the filter. Since there have been no problems I am happy with this filter and will likely buy again in the future. The filter does appear to be made from quality materials.

My mileage on my 2021 Honda CRV dropped 4 miles /gallon with this air filter.
Size: (Pack of 1)
My mileage on my 2021 Honda CRV dropped 4 miles /gallon with this air filter. It did fit well and was easy to install, but then I watched my average around town mileage drop from 29-31mpg to 26-27 mpg thru 2 tank fillups. The Honda repair person said this filter looked like the Honda one and was surprised when we wanted to switch it out. Granted, it looked just like the Honda filter, but the folds on the Honda one are yellowish and I have to think there has to be some difference in the texture. The average mileage went back up within 10 miles of replacing it and 3 fill ups later it has continuously maintained its original average of 29-31 with the Honda filter.

As good as Original Manufacturer Equipment.
Size: (Pack of 1)
Cheaper than having the dealer or oil change store do it. Only takes a minute to replace your existing filter for a lot less than what they want to charge you. High quality too!
