Build item #4 : Northstar Group 31 Battery I had contemplated a Dual Battery setup so I could run all the accessories I ever wanted without ever worrying about the truck not starting. Instead I opted to put a massive @northstarbattery Group 31 AGM battery in place of the House battery. This gives me about 100AH of reserve and 1150 CCA. I also have a Noco Boost to jump the battery if it dies on me. The battery was a tight fit but it works with the factory tie downs and battery tray. I made a new Negative-Fender jumper and had to get a little creative with the battery terminals. Currently I have my Switchpro wired up, HID headlights, a Bluetooth Battery Monitor and a 4awg line run to a BlueSea fuse box in the cargo area. I have a HKB Adjustable Voltage Booster in the mail so I can provide the AGM with the ideal charging voltage.
