The top cover plate has several innovative features in a simple package. All of the wirings have already been done for you, and the smart isolator comes pre-installed. The wires are routed directly to the correct battery post, so there's no guesswork involved to make the connections. Use the extra grommets for routing your own accessory wires cleanly and neatly to the power and ground bus bars. High-quality battery terminal connectors are crimped to the flexible 2 gauge wire connecting the batteries together.

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 allow the 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!
• The alternator will charge both batteries for 1 minute, then switch back to automatic mode to reduce the strain on your alternator

Also includes high amp power and ground bus bars. The bus bars are already pre-wired 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.
