2021 Ford Bronco Dual Battery Kit - Gen 3

This Dual Battery DIY Kit by Genesis Offroad is a direct drop-in replacement for the stock battery tray in Ford Bronco (2021-2025) models. It's designed for efficient charging of both cranking and accessory batteries, compatible with modern high-output alternators. The kit includes a heavy-duty 300-amp continuous battery combiner (500 amps for 5 mins, 2,000 amps for 5 seconds, min. 8 volts to operate), positive and negative bus bars with 3/8", 5/16", and 1/4" studs, and #10 screws. It features a green halo light for connection status, a boost button (Auto, On, Off), and uses 2ga heavy-duty, high strand count, pure copper welding cables with tin-plated pure copper lugs and adhesive-lined heat shrink. No vehicle modifications are required for installation. Recommended battery type: Group 25 (Odyssey ODP-AGM25).
