Good to know: an extra 18 amp hours on a UTV can transform long-ride lighting and audio use. This added capacity powers accessories longer and keeps the starter 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. Its heavy-duty mount resists vibration/impacts for real off-road use.

Arrives fresh, sealed AGM and fully charged with hardware sized for your specific vehicle. The Can Am defender dog box setup needs no daily maintenance, and a quality maintainer is advised to limit sulfation and extend service life.

Order online for clear fitment data and quick delivery, reducing time from purchase to install. This smart upgrade preserves stock starting capacity while adding usable amp-hours for winches, lighting, and stereo power on every trail.

Why a Can-Am Dual Battery Kit Makes Sense for Your Next Ride

If you run lights and audio late, a second power source keeps the starter prepared. 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. Accessory power remains steady for sensitive gear, cutting dimming and dips during spikes.

Confident starts with stock battery starting preserved

The isolator-driven system automatically prioritizes preserving stock battery so your machine cranks strong after a long night with electronics running.

• Reserve capacity: The auxiliary cell adds amp-hour reserve for high-draw gear on trail or at camp.
• Less wear: Accessory offload eases stress on starter circuits and components.
• Automatic management: No manual switching required—system behavior is automatic based on key position.

Can-Am Dual Battery Kit: Features & 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.

An 80A isolator ties sources Key ON and isolates the starter cell 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/fatigue so your install stays neat and serviceable.

UTV Stereo Platinum AGM: sealed, low-maintenance, long-life

Platinum Series AGM comes fresh and pre-charged. Sealed AGM construction resists spill/vibration and needs no routine maintenance.

Adds extra amp hours vs stock for lights, audio, and accessories

• Approximately 18 extra amp-hours compared to stock for longer accessory use.
• 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.

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

Choose the full kit for speed or go bracket-only if you’re reusing a battery. Both choices target 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.

Already have an AGM? Choose bracket-only or wiring-only kits

Cut costs with mount + wiring when you own a spare AGM. It delivers pro routing and solid mounting without unnecessary parts.

Alternative Packages: DS18 bracket/wire-only and AKJ Offroad full kits

• Check AKJ Offroad for a complete package alternative.
• 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.

Select a complete kit for convenience or modular parts to integrate existing gear. Clear fitment guidance cuts wrong orders and gets you the right parts first try.

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’ve already got a compatible battery. Both paths keep the starter reserved and give you usable extra capacity for lights, audio, and recovery gear.

Main components

• 80 amp battery isolator relay to manage charging/isolation.
• Model-specific harness that reduces splices and speeds installation.
• Distribution hardware with fused taps to keep accessory feeds tidy.
• Reinforced bracket to secure components against vibration/impacts.
• Clear documentation to route the harness and terminate distribution points correctly.

Item	Role	Why it matters
Secondary AGM cell	Provides extra amp hours	Keeps starter ready while running accessories
80A isolator relay	Manages charge and isolation	Stops accessory drain on starter
Model harness	Connects components	Easier installs and service access
Distribution block & hardware	Fused accessory feeds	Tidy fused circuits for lights/audio

All parts suit off-road duty, with sealing where needed against dust/moisture. 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 reinforced bracket, set the 2nd cell in place, and follow the harness leads to each terminal.

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. 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 the supplied hardware to make clean grounds and fused distribution points instead of daisy-chaining accessory feeds.

Stage	Action	Why it matters
Mount bracket	Bolt into reinforced points	Maintains clamp load under vibration
Place 2nd cell	Seat and fasten with clamp	Protects terminals and service access
Connect harness	Connect labeled leads/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.

Performance, Charging & Long-Term Care

Robust, steady power sustains aftermarket electronics under load. With proper charging and routine care, reliability repeats season after season.

Look for steadier voltage and better results with amps, winches, and powerful lights. A dedicated auxiliary AGM reduces spike-related dips, keeping audio clean and lights 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 advises between-trip top-offs to preserve capacity and extend life.

• Key OFF isolation preserves stock battery health.
• Running engine alternator replenishes reserves for efficient recharge on long rides.
• Sealed, vibration-resistant AGM design curbs damage over rough terrain.

Aspect	Gain	What to do
Performance	Steadier voltage under load	Add a secondary AGM to support high-draw gear
Charging	Less capacity loss over time	Use a quality charger/maintainer between rides
Long-term care	Extended service life	Do routine maintenance charging on sealed cells

Pro tip: Have a compatible maintainer ready to keep batteries topped. That reduces surprises and helps preserve next-morning starts on every trip.
