Polaris RZR 2014+ 2nd Battery Upgrade Kit – Dual Battery System with 80A Isolator, Wiring & Mounting Bracket

DS18 RZR-DBATT
Polaris RZR 2nd Battery Kit

The RZR-DBATT automatically isolates your factory battery when the ignition is off. That means you can power your lights, sound system, and other accessories without draining the battery that starts your vehicle.

Dual Battery Performance
When the ignition is on, both batteries work together to handle the power load. They also charge simultaneously, giving you more juice without overworking your stator. The built-in 80-amp isolator keeps everything balanced so your system runs strong without blowing anything out.

Built to Work with DS18’s INF-28
This kit is designed specifically to support DS18’s INF-28 AGM battery. It fits securely in the front battery pocket without modifying your RZR, and it’s wired to keep all your accessories running from this second battery by default.

Everything You Need
The RZR-DBATT includes all the wiring and hardware required for a complete install. The cables are pre-sized, OFC-tinned, and built for clean power delivery. The included battery bracket is metal-coated and made to withstand mud, water, heat, and abuse.

Disclaimer: This system fits Polaris RZR 2-seat and 4-seat models from 2014 and up. It’s not compatible with the Pro Series.
