Description

The Genesis Offroad 221-JTDG3-UNDERSEAT mounts an auxiliary battery under the rear driver's side seat of 2021+ Jeep Gladiator diesel and gas models. It includes a Gen 3 Power Hub, pre-wired heavy-duty battery combiner, hardware, adjustable battery brackets, and a GUS Storage Box. The Power Hub automatically connects/disconnects batteries, charging the cranking battery first, then both in parallel, and isolates the cranking battery from aftermarket accessories. Battery cables are 2ga heavy-duty, high strand count, pure copper welding cable with tin-plated copper lugs.
