The Yamaha Wolverine X4 is a four-seat side-by-side utility terrain vehicle (UTV) built for off-road adventures, blending rugged performance with passenger comfort. It’s part of Yamaha’s Wolverine lineup, which includes various models tailored for different terrains and riding styles.
Key Features
- 847cc Twin-Cylinder Engine: Offers strong torque and smooth acceleration, ideal for steep trails and heavy load.
- Ultramatic® CVT Transmission: Delivers seamless power and includes engine braking for downhill control.
- On-Command® 4WD System: Lets you switch between 2WD, 4WD, and 4WD with full differential lock for maximum traction.
- Self-Leveling Rear Suspension: Automatically adjusts to maintain ride height, even with passengers or cargo.
- Quiet Ride Design: Engine mounts and intake/exhaust systems reduce noise and vibration for a more relaxing experience.
Comfort & Versatility
- Seating for Four: Full-size high-back seats with premium cushioning for all passengers.
- Adjustable Driver Ergonomics: Steering wheel tilt and seat adjustability for personalized comfort.
- Foldable Rear Seats: Expand cargo space when not carrying passengers.
Built for Adventure
- XT-R Edition: Includes a WARN® winch, 27-inch radial tires, and special graphics for extreme terrain.
- Speed Management System: Limits top speed for worksite safety or beginner riders.
Whether you’re trail riding, hauling gear, or exploring remote areas, the Wolverine X4 is designed to handle it all with confidence and style.
A dual battery setup for the Yamaha Wolverine X4 isn’t strictly required—but it’s highly recommended if you’re running multiple electrical accessories like winches, sound systems, light bars, or GPS units.
Why Add a Second Battery?
- Protects the Starter Battery: Keeps your main battery reserved for starting the engine.
- Powers Accessories Separately: The second battery handles all add-ons, reducing strain.
- Improves Reliability: Prevents unexpected power loss during long rides or heavy use.
Yamaha’s Official 2nd Battery Kit
- Mounts under the driver seat—no cargo space lost
- Includes cut-to-length wiring and brackets for easy installation
- Compatible with Wolverine X4 models from 2018 to 2024
- Works well with other upgrades like cab heaters and subwoofers
Real-World Use
Owners who’ve installed the kit report smoother winch operation, uninterrupted audio systems, and peace of mind during multi-day expeditions.
If you’re customizing your Wolverine X4 for serious off-road or utility use, a dual battery setup is a smart investment.
Does YXZ 2nd Battery Kit use battery isolator
Yes, the Yamaha YXZ second battery kit typically includes a battery isolator as a core component. This isolator plays a crucial role in managing power between the primary and auxiliary batteries.
🔋 The TRUE® UTV Smart Battery Isolator (SBI) stands out over the standard YXZ 2nd Battery Kit for several reasons—especially when it comes to UTV-specific performance, reliability, and smart power management.
Purpose-Built for UTVs
TRUE SBI UTV battery isolator is engineered specifically for stator-based charging systems, which are common in UTVs like the Yamaha YXZ.- Many generic kits (including some YXZ kits) are designed for alternator systems, which can lead to inefficient charging or battery drain in UTVs.
- TRUE SBI engages only when the starter battery reaches 13.4V, ensuring it’s fully charged before sharing power.
- It disconnects below 12.9V, protecting the starter battery from accessory drain.
- This automated logic prevents manual errors and keeps both batteries healthy
- TRUE kits include fully adhesive-sealed cables and waterproof isolators, ideal for muddy, wet, or humid environments.
- YXZ Dual Battery kits may not offer the same level of environmental protection or cable sealing.
- TRUE SBI isolates accessories to the second battery, preventing power loss during winch use, audio playback, or lighting.
- Some YXZ dual battery kits wire accessories to the main battery, risking starter failure if the second battery drains
- TRUE® kits come with cut-to-length cables, voltmeters, and multiple mounting options (screws, 3M fasteners, or floating install).
XZ 2nd Battery Kit support lithium battery?
The YXZ uses a stator-based charging system, which may not fully charge lithium batteries without a DC-to-DC charger or alternator upgrade. charging behavior differs between lead-acid and lithium batteries. Lithium batteries require precise voltage regulation to avoid overcharging or damage.
Consider upgrading to a True® smart lithium battery isolator like the TRUE® SBI-19L, which is better suited for lithium setups. Monitor voltage levels with a dual voltmeter to avoid deep discharge or overcharge.
