Good to know: 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.

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.

Comes as a sealed AGM, shipped fully charged plus vehicle-matched hardware. The Blackwater tires setup needs no daily maintenance, 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

Run light bars, audio, GPS, and cabin heat while keeping the starter untouched. The accessory supply supplies steady voltage for sensitive electronics, reducing dimming and voltage dips when loads spike.

Confident cranks with stock starting kept intact

Because the isolator protects the stock cell, your engine still cranks strong after a full night of electronics.

• Reserve capacity: Gain additional amp-hours for big-draw accessories during long rides.
• Reduced strain: Offloading accessories reduces stress on the starting circuit and components.
• Smart energy management: Automatic behavior via key position; no manual switch needed.

Can-Am Dual Battery Kit: Features & Benefits

This section highlights the practical advantages of the upgrade for trail use and everyday reliability. It combines automatic management, rugged mounting, and sealed cells so electronics run without risking 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

A reinforced bracket anchors components through washboard trails and hard landings. Resistance to loosening and fatigue keeps installs tidy and easy to service.

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.

Extra capacity over stock for lighting, audio, and gear

• Approximately 18 extra amp-hours compared to stock for longer accessory use.
• Steadier loaded voltage preserves audio clarity and lamp brightness at idle.
• Factory-friendly integration keeps installs neat and durable.

Fitment & Options for Can-Am Models

Choose the right fit for your UTV with model-specific packages that match factory mounting points and wiring paths.

Can-Am Maverick X3 owners get a full 2nd battery kit that includes all wiring and hardware for a turnkey upgrade. If you already own an AGM, the mount-only option from UTV Stereo provides a neat bracket for a tidy install.

Maverick X3: full second-battery kit or dual-mount bracket

Choose the full kit for speed or go bracket-only if you’re reusing a battery. Both approaches aim for 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. That keeps factory clearances intact while adding reliable second battery capacity.

Bracket-only and wiring kits for owners with an AGM

Save money with a wire-and-mount package when you have a spare battery. 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.

What’s Included in the Kit

A clear parts list explains what’s included and how each piece protects the starter while feeding accessories.

Choose a full package with a secondary agm battery or select the bracket-only route if you already own a compatible cell. Both options protect starting power and add capacity for lights/audio/recovery.

Main components

• Battery isolator relay (80A) for charge management between sources.
• Model-specific harness to limit splices and speed installs.
• Power distribution hardware with fused connection points for clean accessory feeds.
• Reinforced bracket to secure components against vibration/impacts.
• Documentation that guides harness routing and proper distribution termination.

Item	Role	Benefit
Secondary AGM cell	Provides extra amp hours	Starter remains ready during accessory use
80A isolator relay	Manages charge and isolation	Prevents accessory draw from draining starter
Model harness	Wiring link	Easier installs and service access
Distribution block & hardware	Fused accessory feeds	Neat fused circuits for lights and audio

All parts suit off-road duty, with sealing where needed against dust/moisture. Integration with existing charge/accessory circuits keeps routing tidy and reliable.

Straightforward Installation

Install is straightforward so your rig stays trail-ready with minimal downtime.

Prep a clear workspace and lay out the labeled parts. Mount the reinforced bracket, set the 2nd cell in place, and follow the harness leads to each terminal.

Key Position Behavior Made Simple

Key ON links sources via 80A isolator; key OFF isolates the starter. This isolator design allows isolate new accessory loads so your starter stays reserved after long 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.

Step	Action	Why it matters
Mount bracket	Bolt into 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. The amp-rated isolator and proper cables keep power delivery steady and protect starting batteries during long rides.

Charging, Performance, and Long-Term Maintenance

Robust, steady power sustains aftermarket electronics under load. 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. The auxiliary AGM trims voltage dips on spikes, keeping sound clean and lights bright.

Use a charger/maintainer to prevent sulfation

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.

• Stock battery health is preserved by isolating starter power Key OFF.
• Running engine alternator replenishes reserves for efficient recharge on long rides.
• Vibration-resistant sealed AGM construction reduces rough-terrain damage.

Aspect	Gain	What to do
Performance	Steadier voltage under load	Use a new secondary agm to support high-draw accessories
Charging	Lower long-term capacity loss	Employ a quality charger/maintainer between outings
Long-term care	Longer service life	Pair sealed cells with routine maintenance charging

Tip: Have a compatible maintainer ready to keep batteries topped. It cuts surprises and preserves next-morning starts on every trip.
