Battery Systems & Accessories

If your rig runs a fridge, lights, comms, or air tools, the real risk isn’t the accessory—it’s the moment your starting battery can’t recover. This collection is built to make power predictable: clean installs, safe wiring, and a setup you can expand as your build grows—whether you’re chasing a Toyota Tacoma dual battery setup, a 4runner dual battery kit, or a jeep dual battery kit.

You’ll find full Gen 3 dual-battery systems for Wrangler JK/JL, Gladiator (gas + diesel, under hood/under seat), Ford Bronco, 4Runner, Tacoma, Tundra, and FJ Cruiser, plus DIY kits for several of those platforms. We also carry dual battery trays for Jeep JK (2007–11 and 2012–18), a JL/JT stock battery replacement kit, and add-ons that make the system feel finished: the Genesis Offroad dual battery kit ecosystem with Genesis power hub, a G Screen display, an engine-on sensor cable, quick-connect cables and jumper cables, marine-style post clamps, ring terminals, and in-cabin power outlets (12V, USB, USB-A/C) with a mounting bezel.

If you’re weighing agm battery vs lead acid, this is where the system approach matters—because cycling accessories on a lead acid battery is where many “mystery electrical issues” start. And if you searched jeep tj parts or dual battery tray for Jeep TJ, note this collection is centered on JK/JL/JT and Toyota/Ford dual-battery solutions—but the wiring principles and power-management add-ons here still help you plan the right direction.
