NEW JK Dual Battery System
When both your batteries are fully charged at 13.2 volts, they are automatically connected and are charged at the same time.What if your cranking battery is somehow drained down too low to be able to start the vehicle? We have a solution for that.
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 begin charging your accessory battery. By only charging one battery at a time, your alternator is protected from excessive strain.
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.Also includes high amp power AND ground bus bars with dust covers. 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.
As long as the combined voltage of the 2 batteries is at least 12.7 volts, 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 switches back over to automatic mode to reduce the strain on your alternator.
A remote status indicator light can be added on your dash to show you when the batteries are connected, indicating that they are both fully charged.
