2021 Diesel Jeep Gladiator JT Dual Battery Kit

The Genesis Offroad 221-JTDG3 Gen 3 Dual Battery System is designed for 2021+ Jeep Gladiator (JT) Diesel models, and is also compatible with gas engine JTs. It mounts a GEN3 Power Hub and an auxiliary battery under the rear driver's side seat within an aluminum storage box. The system features a smart battery combiner that prioritizes cranking battery charging, then links both batteries for simultaneous charging. It automatically separates when voltage drops to prevent drain. The Power Hub includes bus bars with 3/8", 5/16", and 1/4" studs, as well as #10 screws for accessory connections. It also incorporates a boost switch for jump-starting and a G Screen Port for optional monitoring. The kit includes a pre-wired combiner, all necessary hardware, adjustable battery brackets that accommodate Group 35 to Group 31 batteries (approximately 6.8" deep), and heavy-duty 2-gauge copper welding cables with tin-plated lugs.
