2020-2023 Diesel Wrangler Dual Battery Kit - Under Hood
Description
Gen 3 Dual Battery Kit for 2020–2023 Diesel Wrangler JL
This dual battery system delivers reliable power management for Diesel Wrangler builds running winches, compressors, lighting, and other electrical accessories. The Gen 3 Power Hub provides automatic smart battery control, dedicated bus bars for accessory wiring, and an easy under-hood installation designed specifically for JL Diesel models.
Smart Power Management
The integrated battery combiner charges your cranking battery first, then links both batteries to be charged together. When voltage drops, the system separates automatically, ensuring accessories run from the auxiliary battery without draining your starting battery.

Integrated Power Hub
The Power Hub includes positive and negative bus bars with multiple stud sizes for heavy cables and screw terminals for low-amp accessories. A Boost Switch offers Auto, On, and Off modes for full control, and a dedicated port allows simple plug-in compatibility with the optional G Screen monitoring system.
Complete Installation Kit
This package includes the Gen 3 Power Hub, adjustable battery brackets for multiple Group sizes, all required mounting hardware, and high-quality 2ga copper welding cables for durability, conductivity, and long service life.
Designed for Diesel JL Models
This kit mounts the Power Hub on a custom bracket above the factory fuse box. It fits Diesel Wrangler JL (2020–2023) only and will not fit the 392 due to fuse-box height. Auxiliary battery options mount under the rear seat using the included adjustable brackets.
