Can-Am® X3 2nd Battery Kit – Dual Battery System

Boost electrical power and eliminate voltage drop with the UTV Stereo Can-Am X3 2nd Battery Kit.
This complete auxiliary battery system adds a second Platinum Series AGM battery to your X3, delivering more reserve capacity, stable voltage, and reliable performance for stereos, lighting, and accessories.

The built-in battery isolation system ensures your starting battery is always protected—so your X3 starts every time, even after running accessories with the key off.

⚡ How the Dual Battery System Works

• Key OFF:
  Accessories draw power only from the secondary battery
  ✔ Starting battery is fully isolated and protected
• Key ON / Engine Running:
  ✔ Isolator engages
  ✔ Vehicle charging system charges both batteries simultaneously

This setup allows you to run audio systems, light bars, and accessories without risking a dead starting battery.
