Quick fact: an extra 18 amp hours on a UTV can transform long-ride lighting and audio use. That extra capacity lets accessories run longer while your starter stays protected.
Engineered with an 80 amp isolator, it combines sources when the key is on and protects the starter when the key is off, feeding accessories from the auxiliary cell. A heavy-duty mount resists vibration and impacts for true off-road service.
Expect a fresh, sealed AGM that ships fully charged with hardware sized for your specific vehicle. The 2018 Can Am commander doors kit runs maintenance-free day to day, but using a charger/maintainer helps prevent sulfation and lengthen life.
Shop online to confirm fitment and get fast shipping, minimizing downtime from order to install. It preserves stock starting power yet adds usable amp-hours for winches, lights, and stereo on any trail.
Why a Can-Am Dual Battery Kit Makes Sense for Your Next Ride
When your rig needs long nights of lights and music, a dedicated secondary power source keeps the starter ready for the moment that matters. 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
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
The isolator-driven system automatically prioritizes preserving stock battery so your machine cranks strong after a long night with electronics running.
- Extra reserve: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
- Reduced strain: Accessory offload eases stress on starter circuits and components.
- Automatic management: No manual switches—key position controls behavior automatically.
Key Features & Benefits of the Can-Am Dual Battery Kit
This section highlights the practical advantages of the upgrade for trail use and everyday reliability. Automatic control plus a rugged mount and sealed cells keep electronics powered while protecting the starter.
An 80A isolator ties sources Key ON and isolates the starter cell Key OFF. This automation prevents accessory draw from draining your starting source.
Heavy-duty bracket engineered for shock and vibration
The reinforced mount holds steady across washboard and big landings. It resists loosening/fatigue so your install stays neat and serviceable.
UTV Stereo Platinum AGM: sealed, low-maintenance, long-life
The UTV Stereo Platinum Series AGM arrives fresh and fully charged. Sealed AGM construction resists spill/vibration and needs no routine maintenance.
Adds extra amp hours vs stock for lights, audio, and accessories
- About +18 amp-hours vs stock for longer light/audio runtime.
- Cleaner under-load voltage preserves sound quality and lamp brightness at idle.
- The complete battery kit integrates with the factory system 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 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 approaches aim for a factory look and secure fit.
Defender: model-fit second battery kit for stock bay
Defender kits fit stock space and preserve access for service. Factory clearances remain intact while adding reliable auxiliary capacity.
Bracket-only and wire kit options if you already own an AGM battery
Save money with a wire-and-mount package when you have a spare battery. You get clean routing and solid mounting without buying extras.
Alternatives: DS18 wire/bracket-only and AKJ Offroad solutions
- Explore AKJ Offroad for another full package option.
- DS18 offers a wire/bracket-only package and advertises free shipping on U.S. orders.
- 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.
In the Box: What You Get
A clear parts list explains what’s included and how each piece protects the starter while feeding accessories.
Opt for a complete package with the secondary AGM or go bracket-only when you already have a compatible cell. Both options protect starting power and add capacity for lights/audio/recovery.
Primary components
- Battery isolator relay (80A) for charge management between sources.
- Model-specific harness to limit splices and speed installs.
- Power distribution hardware with fused taps to keep accessory feeds tidy.
- Reinforced bracket to secure components against vibration/impacts.
- Clear documentation for routing/termination of harness and distribution.
| Item | Function | Benefit |
|---|---|---|
| Secondary AGM cell | Adds capacity | Keeps starter ready while running accessories |
| 80A isolator relay | Manages charge and isolation | Stops accessory drain on starter |
| Model harness | Wiring link | Simplifies install and service access |
| Distribution block & hardware | Clean accessory feeds | Tidy fused circuits for lights/audio |
All parts are selected for off-road use and sealed where needed to resist dust and moisture. The complete package integrates with existing charge and accessory circuits so routing stays organized and reliable.
Installation Made Straightforward
Simple installation keeps you trail-ready without losing 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.
Simple Key ON/Key OFF behavior
With the key ON, the 80A isolator links sources; key OFF keeps the starter isolated. This design ensures accessories pull from the auxiliary so the starter remains reserved after long stops.
Secure mounting + 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 | Bolt into reinforced points | Handles vibration and maintains clamp load |
| Place 2nd cell | Seat and fasten with clamp | Protects terminals and service access |
| Connect harness | Follow labeled leads and fuse points | Simplifies future upgrades and diagnostics |
Most DIYers can complete the install with basic tools. The amp-rated isolator and proper cables keep power delivery steady and protect starting batteries during long rides.
Charging, Performance, and Long-Term Maintenance
Steady power keeps aftermarket UTV electronics performing under heavy loads. Routine care and proper charging make performance repeatable each 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.
Charger/Maintainer: your sulfation prevention
Use a good maintainer to prevent sulfation, the primary cause of capacity loss in AGM batteries. UTV Stereo recommends topping between trips to preserve capacity and extend life.
- The system preserves stock battery health by isolating starting power when the key is off.
- When running, the alternator replenishes reserves for efficient recovery on long rides.
- Sealed, vibration-resistant AGM design curbs damage over rough terrain.
| Aspect | Benefit | Action |
|---|---|---|
| Performance | Steadier voltage under load | Add a secondary AGM to support high-draw gear |
| Charging | Less capacity loss over time | Employ a quality charger/maintainer between outings |
| Long-term care | Longer service life | Do routine maintenance charging on sealed cells |
Pro tip: Have a compatible maintainer ready to keep batteries topped. This reduces surprises and preserves morning starts trip after trip.
