2020-2023 Diesel Wrangler Dual Battery Kit - Under Hood

The Genesis Offroad 222-JLDG3-UNDERHOOD is a dual battery kit. It features a smart battery combiner (Gen 3 Power Hub) that automatically connects and disconnects batteries, charging the cranking battery first, then linking both. When voltage drops below ~12.7v for a minute, it separates batteries, allowing accessories to run from the auxiliary battery without draining the cranking battery. The Power Hub mounts under the hood over the fuse box. An auxiliary battery (not included) mounts under the back seat using adjustable brackets for Group 35 up to Group 31 batteries. The kit includes heavy-duty 2ga pure copper welding cable with tin-plated copper lugs and adhesive-lined heat shrink. It has positive and negative bus bars with 3/8", 5/16", and 1/4" studs for heavy cables and #10 screws for smaller accessories. An optional G Screen Monitoring System can be plugged in.
