Deluxe Side Post Battery 1/0 Charging System Upgrade Kits


1/0 AWG Charging System Upgrade Kits are ideal for alternators making up to 300 Amps of Output.

Options to Fuse the Charge Lead and / or Upgrade the Battery Clamps are offered below.




Option 1: Fuse the Charge Lead

Most OEM charge leads have a fusible link on them. Its purpose is to protect on-board electronics in the event that the regulator fails and causes “voltage run-away.” Although this is quite uncommon, fusing the charge lead included in any of our kits provides the same protection for your larger than stock alternator.

When choosing this option, we’ll include a Rockford Fosgate ANL Fuse Holder, a 100A, 150A, 175A, 200A, 225A, 250A, or 300A fuse (your choice), and mounting hardware. In addition, we increase the length of the charge lead by one foot to allow you to choose a good mounting location for the fuse holder and still have a nice smooth run from the alternator to the battery.

Option 2: Upgrade the Battery Clamps

What if you need to connect more than two really large-gauge cables to the battery? No problem. Our XB-BTU clamps have three cable locations, each accommodating 1/0 AWG, 2 AWG, 4 AWG, or 8 AWG. You can also fit multiple 4 AWG or multiple 8 AWG cables in a single location.
