Good to know: with 18 additional amp hours, long rides feel different for lights and sound. More capacity means longer accessory runtime while safeguarding the starter.
A purpose-built 80A isolator links both batteries Key ON and isolates the starter Key OFF so accessories pull from the second battery. Its heavy-duty mount resists vibration/impacts for real off-road use.
Comes as a sealed AGM, shipped fully charged with hardware sized for your specific vehicle. The back seat for 4 wheeler system is maintenance-free in daily use, though a charger or maintainer is recommended to prevent sulfation and extend life.
Shop online for clear fitment and fast delivery so a customer can move from order to install with minimal downtime. You keep stock starting capacity and gain usable amp-hours for winch, lights, and audio everywhere you ride.
Top Reasons to Run a Can-Am Dual Battery Kit on Your Next Trip
When your rig needs long nights of lights and music, a dedicated secondary power source keeps the starter ready for the moment that matters. With an 80A isolator, Key ON combines sources; Key OFF isolates the starter so accessories draw from the auxiliary battery.
Use accessories freely and preserve your stock battery
Drive light bars, audio, GPS, and heaters without draining the starter. Accessory power remains steady for sensitive gear, cutting dimming and dips during spikes.
Confident starts thanks to preserved stock starting power
An isolator-managed system preserves the stock battery so cranking stays strong after long accessory use.
- Reserve capacity: A second battery gives extra amp hours for high-draw gear at camp or on long rides.
- Less wear: Offloading accessories reduces stress on the starting circuit and components.
- Automatic management: Automatic behavior via key position; no manual switch needed.
Can Am dual battery kit Features and Benefits
Practical advantages for real trails and day-to-day reliability. Automatic control plus a rugged mount and sealed cells keep electronics powered while protecting the starter.
With an 80 amp isolator, sources link Key ON and the starter is isolated Key OFF. Automation prevents accessory drain on the starting battery.
Rugged mounting bracket for vibration and hits
A reinforced bracket anchors components through washboard trails and hard landings. It resists loosening/fatigue so your install stays neat and serviceable.
UTV Stereo Platinum AGM: sealed, low-maintenance, long-life

- Steadier loaded voltage preserves audio clarity and lamp brightness at idle.
- The complete battery kit integrates with the factory system for a neat, durable install.
Model Fitment and Options for Can-Am Owners
Select the kit that matches factory mounts and wiring for your model.
Maverick X3 owners get a full 2nd battery kit that includes all wiring and hardware for a turnkey upgrade. If you’ve got an AGM already, the mount-only bracket from UTV Stereo makes for a tidy install.
Maverick X3 Options: complete kit or bracket-only
Pick a complete kit for fast setup or the bracket-only path when reusing an existing cell. Both choices target a factory look and secure fit.
Defender Fit: second-battery kit sized for the stock compartment
The Defender kit is built to fit the stock space and preserve service access. Factory clearances remain intact while adding reliable auxiliary capacity.
Already have an AGM? Choose bracket-only or wiring-only kits
Save by using a wire-and-mount package if you already have a battery. It delivers pro routing and solid mounting without unnecessary parts.
Alternative Packages: DS18 bracket/wire-only and AKJ Offroad full kits
- AKJ Offroad offers another full kit option.
- DS18 lists bracket/wire-only packages with free U.S. shipping advertised.
- All are engineered to model geometry for factory-look installs that hold up off-road.
Pick what fits your build—complete kit for convenience or modular parts to reuse gear. Clear fitment notes reduce wrong orders and help each customer get the right parts the first time.
Kit Contents
A clear parts list explains what’s included and how each piece protects the starter while feeding accessories.
Pick a full package including the auxiliary AGM, or choose bracket-only if you already own a compatible cell. Either way preserves the starter and adds usable capacity for lights, audio, and recovery tools.
Main components
- Battery isolator relay (80A) for charge management between sources.
- Model-specific harness that reduces splices and speeds installation.
- Power distribution hardware with fused connection points for clean accessory feeds.
- Bracket, reinforced, to resist shock and vibration.
- Clear documentation for routing/termination of harness and distribution.
| Component | Role | Why it matters |
|---|---|---|
| Secondary AGM cell | Provides extra amp hours | Keeps starter ready while running accessories |
| 80A isolator relay | Controls charge/isolation | Prevents accessory draw from draining starter |
| Model harness | Wiring link | Easier installs and service access |
| Distribution block & hardware | Clean accessory feeds | Neat fused circuits for lights and audio |
All parts are selected for off-road use and sealed where needed to resist dust and moisture. Integration with existing charge/accessory circuits keeps routing tidy and reliable.
Easy, Straightforward Install
Simple installation keeps you trail-ready without losing hours in the garage.
Prep a clear workspace and lay out the labeled parts. Install the bracket, seat the second battery, then connect the labeled harness leads.
Simple Key ON/Key OFF behavior
The 80 amp isolator links both sources when the key is on and lets the starting cell remain battery isolated when the key is off. The design routes accessory load to the aux battery, preserving the starter after extended stops.
Secure bracket placement and clean harness routing
Route the harness along factory paths, secure it with clips, and add abrasion protection at pinch points. Use supplied hardware for clean grounds and fused distribution rather than daisy-chaining.
| Stage | Action | Reason |
|---|---|---|
| Mount bracket | Secure to reinforced points | Maintains clamp load under vibration |
| Place 2nd cell | Seat battery and clamp firmly | Keeps terminals safe and serviceable |
| Connect harness | Follow labeled leads and fuse points | Makes upgrades and diagnostics easier |
Basic tools are enough for most mechanically inclined owners. The amp-rated isolator and proper cables keep power delivery steady and protect starting batteries during long rides.
Performance, Charging & Long-Term Care
Steady power keeps aftermarket UTV electronics performing under heavy loads. With proper charging and routine care, reliability repeats season after season.
Expect steadier voltage with better performance for amps, winches, and high-output lights. A dedicated auxiliary AGM reduces spike-related dips, keeping audio clean and lights bright.
Prevent sulfation with a charger/maintainer
Regular charging with a quality maintainer prevents sulfation, which is the leading cause of capacity loss in agm battery designs. UTV Stereo recommends topping cells between trips to preserve capacity and extend lifespan.
- Stock battery health is preserved by isolating starter power Key OFF.
- While running, the alternator replenishes reserves so long rides restore charge efficiently.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Area | Benefit | Action |
|---|---|---|
| Performance | Steadier voltage under load | Use a new secondary agm to support high-draw accessories |
| Charging | Less capacity loss over time | Employ a quality charger/maintainer between outings |
| Long-term care | Extended service life | Do routine maintenance charging on sealed cells |
Pro tip: Keep a suitable maintainer handy to stay topped up. That reduces surprises and helps preserve next-morning starts on every trip.
