RZR® Pro Series 2nd Battery Kit – 4-Seat Models

Boost your UTV’s electrical power and eliminate voltage drop with the UTV Stereo Pro Series 2nd Battery Kit.
This system is designed specifically for 4-seat Polaris RZR Pro models, adding a second 30Ah Platinum Series AGM battery to dramatically increase reserve capacity and voltage stability.

With this kit installed, your stereo plays longer, lights shine brighter, and aftermarket accessories perform at peak output—even during long rides or low RPM operation.

⚡ Why Add a Second Battery?

Modern UTVs demand more power than a single factory battery can reliably provide. Adding a second battery:

• Maintains higher voltage under load
• Prevents system shutdowns and dimming lights
• Protects your starting battery
• Supports high-draw accessories like audio systems, light bars, winches, and communication gear

🔌 Battery Maintenance Recommendation

To preserve performance and maximize battery lifespan, AGM batteries must remain properly charged during storage.

We strongly recommend pairing this kit with:

• UTV Stereo 12V Automatic Battery Charger / Maintainer, or
• UTV Stereo 55 Amp Power Pack System

This prevents sulfation, preserves capacity, and ensures your UTV is always ready to ride.

✅ The Ultimate Power Upgrade for 4-Seat RZR Pros

If you’re running a stereo, lighting, or multiple accessories, this Pro Series 2nd Battery Kit is not optional—it’s essential. Add power, protect your electrical system, and ride longer with confidence.
