The Titan is equipped with a 20A step down converter to convert the 24V battery to a regulated 13.8V (typical fully charged car battery voltage). If you need more than 20A, we suggest that you purchase a larger step down converter. You can typically find a 100A 24V to 13.8V step down converter for around $100-$150 on Ebay, Amazon, or other online stores. You can use our external battery connection wire to connect the step down to the AC charging port (for the 24V input to the step down). You simply connect the input of the step down converter to the Anderson plug and plug it into one of the AC charging ports. The output of the step down converter should be wired into a fuse, fuse block, or breaker, and then to your application.
