Surprising fact: adding 18 amp hours to your UTV changes how you use lights and audio on long rides. More capacity means longer accessory runtime while safeguarding the starter.
This purpose-built upgrade uses an 80 amp isolator so, with the key on, both sources share power, and with the key off, the starting unit is safe while accessories draw from the second battery. The rugged mount fights vibration and shock for authentic off-road duty.
Expect a fresh, sealed AGM that ships fully charged plus vehicle-matched hardware. The Polaris UTV snow plow 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. It preserves stock starting power yet adds usable amp-hours for winches, lights, and stereo on any trail.
Top Reasons to Run a Can-Am Dual Battery Kit on Your Next Trip
For long nights of lights and music, a dedicated auxiliary source keeps the starter ready when you need it. An 80A isolator ties both batteries Key ON and isolates the starter Key OFF so accessories pull from the aux cell, not the stock one.
Power accessories while protecting your stock battery
Power more accessories like light bars, sound systems, GPS, and in-cab heaters without depleting your starting source. The accessory supply supplies steady voltage for sensitive electronics, reducing dimming and voltage dips when loads spike.
Confident starts with stock battery starting preserved
Because the isolator protects the stock cell, your engine still cranks strong after a full night of electronics.
- Reserve capacity: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
- Reduced strain: Offloading accessories reduces stress on the starting circuit and components.
- Smart energy management: No manual switches—key position controls behavior automatically.
Can-Am Dual Battery Kit: Features & Benefits
Practical advantages for real trails and day-to-day reliability. It combines automatic management, rugged mounting, and sealed cells so electronics run without risking the starter.
With an 80 amp isolator, sources link Key ON and the starter is isolated Key OFF. This automation prevents accessory draw from draining your starting source.
Rugged mounting bracket for vibration and hits
The reinforced mount holds steady across washboard and big landings. It resists loosening and fatigue so the install stays tidy and serviceable.
UTV Stereo Platinum Series AGM: sealed, maintenance-free, long-lasting
Platinum Series AGM comes fresh and pre-charged. As a sealed agm battery, it resists spills and vibration and needs no routine maintenance.
Extra capacity over stock for lighting, audio, and gear
- Gain about 18 amp hours versus stock for longer runtime with lights and audio.
- Steadier loaded voltage preserves audio clarity and lamp brightness at idle.
- Complete kit integrates with factory wiring for a neat, durable install.
Fitment & Options for Can-Am Models
Pick model-specific packages that match factory mounts and wiring paths.
Maverick X3 owners can choose a full second-battery kit with all wiring/hardware for turnkey install. If you’ve got an AGM already, the mount-only bracket from UTV Stereo makes for a tidy install.
Maverick X3: complete 2nd battery kit and dual battery mount
Go complete for quick setup, or bracket-only to reuse an existing cell. Both approaches aim for a factory look and secure fit.
Defender: model-fit second battery kit for stock bay
The Defender kit is built to fit the stock space and preserve service access. That keeps factory clearances intact while adding reliable second battery capacity.
Bracket-only and wire kit options if you already own an AGM battery
Cut costs with mount + wiring when you own a spare AGM. You get clean routing and solid mounting without buying extras.
Other Options: DS18 bracket/wire packages and AKJ Offroad kits
- Check AKJ Offroad for a complete package alternative.
- DS18 has wire/bracket-only options and promotes free shipping in the U.S..
- Each product is engineered around model geometry so the install looks factory and stays secure on rough trails.
Pick what fits your build—complete kit for convenience or modular parts to reuse gear. Fitment notes minimize mistakes and help you order correctly the first time.
In the Box: What You Get
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. Both paths keep the starter reserved and give you usable extra capacity for lights, audio, and recovery gear.
Primary components
- 80 amp battery isolator relay to manage charging/isolation.
- Harness, model-specific, to simplify wiring and speed install.
- Power distribution hardware with fused taps to keep accessory feeds tidy.
- A reinforced bracket that secures the assembly against vibration and impacts.
- Clear documentation for routing/termination of harness and distribution.
| Component | Function | Why it matters |
|---|---|---|
| Secondary AGM cell | Adds capacity | Starter remains ready during accessory use |
| 80A isolator relay | Controls charge/isolation | Prevents accessory draw from draining starter |
| Model harness | Connects components | Easier installs and service access |
| Distribution block & hardware | Fused accessory feeds | Tidy fused circuits for lights/audio |
Parts are off-road ready and sealed as needed for dust/moisture resistance. The complete package integrates with existing charge and accessory circuits so routing stays organized and reliable.
Straightforward Installation
A straightforward install keeps your rig trail-ready without hours in the garage.
Start with a clear workspace and the labeled parts laid out before you. Mount the bracket, place the second cell, and route the harness to labeled terminals.
Key Position Behavior Made Simple
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. This isolator design allows isolate new accessory loads so your starter stays reserved after long stops.
Secure bracket placement and clean harness routing
Use factory routing, secure with clips, and sleeve abrasion 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 and fasten with clamp | Keeps terminals safe and serviceable |
| Connect harness | Connect labeled leads/fuse points | Simplifies future upgrades and diagnostics |
Most DIYers can complete the install with basic tools. Amp-rated isolator plus proper cabling stabilize power and protect the starter on long rides.
Charging, Performance, and Long-Term Maintenance
Steady power keeps aftermarket UTV electronics performing under heavy loads. Proper charging and routine care make that reliability repeatable season after season.
Expect steadier voltage and improved performance for audio amps, winches, and high-output lights. A dedicated secondary agm reduces dips during spikes so sound stays clean and lamps stay bright.
Charger/Maintainer: your sulfation prevention
Regular top-offs with a quality maintainer help prevent sulfation—the main cause of capacity loss in AGM designs. UTV Stereo recommends topping between trips to preserve capacity and extend life.
- Key OFF isolation preserves stock battery health.
- While running, the alternator replenishes reserves so long rides restore charge efficiently.
- Sealed, vibration-resistant agm battery construction reduces damage from rough terrain.
| Aspect | Gain | Action |
|---|---|---|
| Performance | Stable voltage under load | Add a secondary AGM to support high-draw gear |
| Charging | Lower long-term capacity loss | Employ a quality charger/maintainer between outings |
| Long-term care | Longer service life | Do routine maintenance charging on sealed cells |
Tip: Keep a compatible maintainer on hand so your batteries stay topped off. It cuts surprises and preserves next-morning starts on every trip.
