Dual Battery Isolator Kit 12V Fits Car Watercraft Marine ATV UTV 4WD Rzr RV 140A



warranty:One year warranty

high quality!

How it works: The smart battery isolator allows two batteries to be charged at the same time. When the engine is started and the start battery reaches 13.4 volts, the relay engages, allowing two battery banks (start and accessory) to be charged simultaneously.

Perfect for RV, Marine, Automotive, Diesel applications

Kits comes with:

1-Smart Battery Isolator with mounting screws

1-6 meter (over 18 feet) length of 10mm red battery cable with eyelets on both ends

1-2 foot length of black battery cable

2-Positive Marine Battery terminals

1-Negative Marine Battery terminal

1-10 gauge Copper crimp lug

2-16-8 Copper crimp lugs

2-Red heat shrink

1-Insulated blue ring terminal

6-8 inch black cable ties

12V 140A isolator with Cut-In:13.3V, Cut-Out:12.8V

Easy 3 wire connection at the battery. No need to bypass existing alternator wiring.

The smart isolator has no voltage drop. Conventional diode isolators incur a minimum of 0.6 volt drop. Compact size - No large heat sink

Operation Temperature Range: -30 to 105°C (-22°F to 221°F)

Size: 2.5” x 2.5” x 2”

A smart battery isolator is the ultra-simple and most technologically advanced method of automatic battery isolation. These units can be installed between batteries with a common ground to automatically control the charging process to the batteries but continue to provide isolation when a charging source is unavailable. The small size and rugged construction of these units allow for quick simple installation for even the most novice DIYer. The smart isolator is also “Dual Sensing” which senses the charge of both batteries. If either battery is receiving a charge, e.g. a battery charger is connected to the auxiliary battery; the relay will engage and charge both batteries. The advanced technology always ensures that the first battery is fully charged (13.4v) before the connection is made to the second battery. This prevents problems that may result from your charging source being too low in amps to charge all batteries at once. If placed in linear sequence between each battery the isolator units can provide proper charging for several batteries in multiple battery setups such as in larger boats that may have 2 or more house batteries.

Professional installation is recommended.
