The top cover plate has several innovative features in a simple package. All of the wiring has already been done for you, and the smart isolator comes pre-installed. The welded gussets on top have holes with grommets to route the wires directly to the correct battery post, so there's no guess work involved to make the connections. High quality battery terminal connectors are crimped to the flexible 2 gauge wire connecting the batteries together. With all the wiring integrated into the top plate, servicing your batteries has never been easier. Simply pull the terminals off the battery posts, remove the 4 bolts securing the lid, and all the wiring can be lifted up and out of the way to service your batteries when necessary.
The included smart isolator gives you automatic control of all the charging functions with no interaction required
Here's how it works:
- When both your batteries are fully charged at 13.2 volts, they are automatically connected and are charged at the same time
- When you park and turn off the engine, but continue to use accessories such as lights or the stereo or a CB, both batteries begin to drain down
- When your main cranking battery reaches 12.7 volts, the smart isolator separates the batteries, so that your cranking battery will have enough power to start the engine. The second battery continues to power your accessories for as long as it will last
- After you crank the vehicle, your main cranking battery will be charged up to 13.2 volts first, and then the isolator will all charging of your accessory battery
What if your cranking battery is somehow drained down too low to be able to start the vehicle? We have a solution for that
- Press the Start Boost button and the isolator will connect both batteries together for 1 minute, acting like built-in jumper cables to jump start your engine off your accessory battery
- As long as the accessory battery has enough power, you'll be able to start your vehicle instead of being stranded with a dead battery! By only charging one battery at a time, your alternator is protected from excessive strain
Also includes high amp power and ground bus bars. The bus bars are already prewired to the accessory battery. Now you can quickly and easily connect your winch, lights, amplifiers, and lots more while keeping the wiring neat and orderly. Your winch or other high-amp cable lugs go onto the large center post on the bus bars, and all your other accessories go directly to the smaller screw terminals on the bus bars.
- The 4Runner dual battery kit comes with a smart isolator and solenoid rated to handle a continuous 200 amps of current. It will handle spikes of up to 750 amps for up to 30 seconds
